Saving on energy costs by using the right equipment

Australians are likely to experience a 53.8 per cent increase in energy prices in Victoria from the fourth quarter of 2018 to the first quarter of 2019. Other states are expected to see similar increases, according to predictions from the Australian Energy Regulator. For Victoria, this would mean the dollar per megawatt hour could jump from $84 to $129.

Despite a strong surge in prices, the four-year forecast estimates a decline in Victoria to $68.5 per megawatt hour by the fourth quarter of 2019, but it could climb to $80.4 per megawatt hour in the first quarter of 2021. New South Wales is expected to see a lower first quarter in 2019 than Victoria, but prices remain slightly higher throughout the year. In the first quarter of next year, NSW is expected to reach $105 per megawatt hour and it should increase to $71 per megawatt hour in the final quarter of 2019.

With numbers fluctuating in the next five years, saving on energy where possible is becoming increasingly important to companies, including food and beverage manufacturers. MHE-Demag helps businesses reduce their energy consumption and minimise costs by offering specialised equipment and services. The company provides loading bay solutions for food storage and cold chain operators, with products including dock levellers, dock shelters and doors.

MHE-Demag managing director Vince Di Costanzo said the company’s unique, customisable range of products and staff expertise helps create long-term savings. “With energy costs being higher than any other country, it’s a real focal point for business survival,” he said.

In late-2018, the company completed a project with a large food supplier in Melbourne, which stocks a range of fresh and frozen foods as well as drygoods and paper products. “They do everything from jarred and canned food to oils, pastas, rice and an array of seafood. It’s quite a covering,” said Di Costanzo. MHE-Demag installed dock levellers, rapid rail doors, high-speed roller shutters and door seals at the factory.

“We have high-speed, insulated freezer doors that maintain temperatures from sub-zero to five degrees. By maintaining environmental integrity in the cold storage environment, it maximises energy efficiency.” Dock shelters and seals for incoming and outgoing products helped achieve that, he said.

A hands-on role throughout the project was required to ensure the client received the best service and made cost savings where possible. By offering personalised project management, MHE-Demag was able to steer the company away from a more expensive door installation to an option that would lower their energy bill. “Where they were wanting two doors in one location, we were able to create a one door solution, meeting the same requirements.” The change in design means the company only needs to run power to a single door.

“In our product offering, we were able to provide the shelter and seals to the required measurements and we’ve created better insulation for this company. The energy loss has been dramatically reduced,” said Di Costanzo.

Service after Installation
MHE-Demag also believes in preventative maintenance and ongoing support that will ensure the products last. “We make sure there’s an inspection carried out on all of the seals. Where ever there’s a sign of wear and tear we can replace, or repair, or put other protocols in place,” said Di Costanzo.

However, there are already measures in place to minimise products breakage once it is installed. The door curtains on MHE-Demag’s high speed doors, for example, are self-repairing. If the door curtain comes off of the track, for instance in the event of impact with a forklift, the system will guide the curtain back into the tracks on the next cycle. They are made without any rigid pieces, making them safe for use by equipment and staff.

“To minimise energy consumption, a zipper style fixture of the curtain retention within the guides or tracks creates a more reliable seal for minimal temperature or air loses compared to many rapid roller doors with fabric curtains,” said Di Costanzo.

With many of the products, such as the dock leveller, manufactured in Australia, MHE-Demag is also able to provide items quickly. “We have better control of the manufacturing and we tend to have a higher quality, stronger product,” he said.

Energy consumption grows  
As Australian energy consumption continues to grow, MHE-Demag aims to help companies steer clear of unnecessary power usage. An Australian government Department of the Environment and Energy, 2018 Australian Energy Update report shows that the electricity supply, transport and manufacturing sectors accounted for almost three-quarters of Australian energy consumption in 2016–17. The electricity supply sector only accounted for 28 per cent of energy consumption in 2016–17.

Australia’s energy consumption rose by 1.1 per cent in 2016–17 to reach 6,146 petajoules. This compares to an average growth of 0.8 per cent a year over the past 10 years. Growth in 2016–17 was 65 petajoules, the same amount of energy as filling a 55-litre tank of petrol 34 million times, the government report indicates.

SEW-Eurodrive equipment helps Yalumba Winery save on energy costs

At a time when energy costs continue to spiral upwards, saving energy is not just good for the environment, it is important for the commercial bottom line.

According to Jesse Auricht, engineering manager, Yalumba Winery, decisions taken when planning a bottling upgrade at the plant have turned out well in both regards.

He said the choice of energy-efficient SEW-Eurodrive Movigear mechatronic drive units to keep the conveyor lines and bottles moving, contributed to this positive outcome.

The winery is serious about reducing energy costs and monitors energy consumption continuously. Typically, half the cost of energy is based on network charges, so it is important to avoid any spikes in consumption as the wine bottles are filled, capped, labelled and packed in the bottling plant, said Auricht.

“In the energy market, 50 per cent of your cost can be dictated by a half-hour event,” he said. “If you hit that peak once, depending on the time of day, you’ll see an ongoing energy cost increase.”

John Gattellari, national industry specialist – food & beverage, with SEW-Eurodrive, said the Movigear units are designed to minimise the use of electrical power and help manufacturers make savings. Movigear complies with efficiency class IE4 (super premium efficiency) and reduces energy costs by up to 50 per cent, due to the high efficiency of all its components.

Planning pays off
Once it was clear that the plant needed refurbishing, the owners decided not to rush in. Starting with their own design concepts, they issued a tender for detailed design and implementation of the project, and awarded it to Foodmach, a specialist Australian provider of machinery design, manufacturing and control services.

Working closely with Yalumba, Foodmach designed and installed the new conveyor and line control system. The revamped system consisted of the original bottling line with new controls, conveyor and palletisers, and a second line with a new de-palletiser, filler and packer.

SEW-Eurodrive’s engineering and customer service, together with energy efficient Movidrive mechatronic drive system and high precision servo motors and Movidrive controllers, were fundamental in obtaining the desired result.

In addition to saving costs by reducing energy consumption, the upgrade also led to a safer work environment and a reduction in noise.

Noise amplification and reduction
Another key issue was that of noise, especially given the running speeds of the conveyors. Line 2, which is used for wine only, runs at 12,000 bottles per hour. “You get glass bottles banging into each other at that rate and it’s noisy – and potentially dangerous as well,” said Auricht.

Trevor Burgemeister, process control technician at Yalumba, said that to alleviate the noise and danger of uncontrolled collisions, the system had to be designed to detect when bottles were about to collide. When this happened, it set a maximum collision speed.
Auricht said to achieve this, the drives needed to be accurate, reliable, efficient and controllable. As for the noise component, he said that the Movigear is so quiet it’s negligible in comparison to the rest of the system.

These characteristics, along with past performance and a strong relationship, were major factors in the choice of SEW-Eurodrive.

“They have been a solid partner of ours for a long time. It’s a recognised brand and we’ve had a lot of success,” he said.

No pressure
The key to reducing the noise is creating a pressureless line. In this case, pressure refers to the accumulation of bottles at any point on the conveyor system. It occurs when the conveyor is transporting more bottles than the individual machine process rate. If a processing machine for filling, capping or labelling is operating at a slower speed than bottles are being delivered, the bottles bump into each other, and that familiar sound of glass against glass can be heard. On a grand scale though, it’s not a pleasant clinking sound that you might hear in a restaurant. At a rate of thousands of bottles per hour, it’s more of a cacophony.

Auricht said that if the conveyor keeps running when this happens, the pressure continues to build up. This means energy wastage, inefficiency and noise, along with wear and tear on all the conveyors.

On Line 1, which is used for many different bottle types ranging from sparkling wine with a cork, to table wines with screw tops, the flow is between 5,000 and 9,000 bottles per hour. While the aim is zero pressure on the conveyors, the processing machines require a degree of pressure to function correctly.

To achieve this, the conveyors on this line run at set speeds, while the line’s process machines vary their speed as necessary to maintain head pressure of between five and eight bottles.

In the Foodmach, line control system speeds are controlled by software programmed according to a “recipe” that varies for each production variety.

The recipe specifies which processing machines are required for the product and also their operating parameters. Recipe data – speed, diameter of bottle, gap between bottles and the like – is communicated from the programmable logic controller (PLC) to the SEW-Eurodrive gears and units. These are calibrated so that the speed of the conveyor is set correctly. Burgemeister says that connecting the motion-detecting sensors to the motors and gear units, in order to manage the flow of bottles, was a simple operation. “It was just a matter of plugging the photoelectric in,” he said.

Poetry in motion
Correct flow is set up at the start of the operation on the Foodmach de-palletisers, where thousands of bottles per hour are fed into the two bottling conveyor lines. At this point, several mini conveyor lines, running side by side and at different speeds, cause bunched-up groups of bottles to be fed into a single line. Complex programming, communicated to each Movigear drive in the system, makes the operation look easy. For Auricht, this is what good engineering is all about. He describes the process with a single word – poetry.
“This was probably one of our most successful projects undertaken – both in timeframes and outcomes,” said Auricht. “In the scheme of things, the premium for the high-efficiency, low-energy drives was not that much. Looking back on it now, it absolutely was the right decision.”

Meeting the food & beverage industry’s energy needs

With wholesale energy prices in Australia predicted to rise by as much as 200 per cent over the next three years, the need to manage energy costs in business is becoming urgent.

Energy accounts for one of the most significant areas of cost for the majority of industrial businesses – especially those with temperature-intensive processes such as in food and beverage manufacturing.

Australian Food and Grocery Council CEO, Tanya Barden says the food and beverage industry is facing increasing pressure due to high energy costs.

“There is no doubt Australia’s largest manufacturing sector is facing an environment where input costs are rising on everything from commodities to labour to energy, and six years of retail price deflation continues to cut margins, placing the sector under increasing pressure,” she said.

“We are expecting these pressures to only increase as energy, especially gas, has seen a doubling and in some cases a tripling of price that is likely to have dire consequence for Australian jobs and investment, with some companies re-assessing their long-term future in Australia.”

Australian Meat Industry Council CEO, Patrick Hutchinson said high energy prices have already placed meat processing jobs at risk.

“We have one lamb processor in Victoria who is seeing close to $600,000 to $1 million increase in energy prices in a year,” he said.

“We’ve also seen major domestic beef processing go in Ipswich with 500 jobs.” “It’s never been more important to manage energy costs.”

There is also constant pressure on the food and beverage processing industry to reduce emissions with many organisations looking to optimise their energy use.

In its White Paper Industrial Energy Strategic Opportunity, design, build and facilities management specialists Wiley predict the future for industrial energy and explain what businesses need to do to gear up for the opportunities ahead.

In the White Paper, Brett Wiskar, R&D and Innovation Director at Wiley, outlines effective solutions for businesses in the food and drink processing sector to harness new technologies and build long- term resilience in energy efficiency, supply and cost and ultimately remain competitive.

The solutions include increasing efficiency and reducing consumption, introducing solar production either, in isolation or in conjunction with battery storage. CONT

“To reduce consumption and increase efficiency, businesses need to optimise the use of their existing equipment, install effective metering equipment and ensure effective shutdown procedures are in place.” said Wiskar.

“Operating temperatures and the pressure of equipment and processes should also be optimised and heat gain into fridges and boilers should be minimised as much as possible. Maintaining equipment is also important.”

According to Wiskar, installing solar panels and storing the energy for later use can be one of the most effective means in reducing energy bills.

“Australia has ample access to solar with falling install costs starting to drive up larger scale industrial adoption. In addition to generating your own energy with solar panels, energy captured at peak times can also be stored for later use.”

“There’s now a number of technological solutions on the market for effectively storing energy and we continue to monitor and work with the leading developers in the world to ensure the best technology is available to the Australian manufacturing industry,” Wiskar said.

Industry and executive leaders must ensure their operations remain profitable into the future in spite of energy volatility and growing costs.

 

Clean energy target ‘critical’ for Australia’s agricultural future

Australia’s food industry is taking a hit by the ongoing energy crisis, according to the agriculture industry.

A warning has been fired that the country’s ability to deliver affordable food and fibre is at threat, as federal and state energy ministers met to discuss the industry’s future.

The Council of Australian Government’s energy council meeting in Brisbane heard concerns from Labor states, which are calling for policy that aims to encourage investment and the delivery of a clean energy target (CET).

“Importantly, governments will be provided with greater visibility of retail electricity prices, retail margins and factors affecting price, to ensure they are in a stronger position to respond to any inappropriate market practices,’’ said federal Environment Minister Josh Frydenberg .

While the council agreed on 49 recommendations of the Finkel Review, there were fears that rising costs would lead to mothballing of important infrastructure.

Claiming that CET was “critical”, Queensland Energy Minister Mark Bailey said the Finkel Review “clearly showed a CET would deliver lower electricity prices, more investment and lower emissions compared to a business-as-usual approach”.

Gas prices still putting the heat on manufacturers

Chemistry Australia CEO Samantha Read has said that manufacturers in the Australian chemistry industry are not seeing an end to rising east coast gas prices.

“While there has been some important Government action, the crisis is not over,” said Read.

“If anything, there appears to be continued upward pressure both on the cost of gas and its delivery. Members are still reporting increases of between 30 per cent and 60 per cent in negotiating new gas energy contracts.

“Australia will pay a heavy price with job losses across the manufacturing sector. This is a double-whammy hitting everyday Australians who are already struggling at home with rising power and gas bills.”

Gas is particularly essential to the business of chemistry. The Australian chemistry industry uses 10 per cent of Australia’s domestic gas for its molecular properties to create a huge range of products including fertilisers for  crops, smart packaging to keep our food fresher for longer, and more.

The 2014 Deloitte Access Economics Report forecast losses of 14,500 jobs between 2014 and 2021 in net present value terms, due to rising gas costs and constrained supply.

According to Read however, there are real industry concerns that the job losses may be even higher than forecast. This is because the modelling applied was based on gas in the $8 to $10 per gigajoule range, however some manufacturers are being faced with $12 to $16 per gigajoule, or even higher.

“These shifts of a dollar or two per gigajoule don’t illustrate the full impact to businesses, where the actual dollar effect is in the hundreds of thousands, and in some cases millions, added to input costs,” said Read.

“We welcome the Federal Government’s announcement last week that the Australian Domestic Gas Safeguard Mechanism is now active. This provides some short-term supply certainty for gas buyers.

“Short-term measures help give businesses time to assess their position. But it’s the long-term vision that will ultimately decide whether a business continues operations in Australia.

“If a business can make it through this period of crisis, will there be more gas supply, at more competitive prices, into a more transparent market.

The most fundamental part of the mechanism is new gas supply, according to Read. She believes that if all states were to adopt the ACCC’s recommendation for a case-by-case assessment on projects, this would open investment and jobs growth potential.

“There has been a lack of understanding of how critical domestic gas is to job creation,” said Read.

“Australia has an abundance of gas; our ambition should be greater than just meeting current day demand. Gas can create opportunities right through Australia’s value chains, and be a catalyst for investment just as it is in other countries endowed with similar gas reserves.”

Gas is particularly important to the business of chemistry. It is important for process energy, and it is also a non-substitutable ingredient for advanced manufacturing, according to Chemistry Australia.

The Australian chemistry industry uses 10 per cent of Australia’s domestic gas for its molecular properties to create a huge range of products essential to peoples’ everyday lives. These include fertilisers for crops, cleaning products for health and hygiene in homes and hospitals, and smart packaging to keep food fresher for longer.

 

Turnbull promises manufacturers new gas deal

The government has promised to halve the price manufacturers pay for gas to ensure affordable supplies across the industry.

Prime Minister Malcom Turnbull has noted that 65,000 jobs which are reliant on gas are at risk and would remain that way until action was taken.

The government has announced that Resource minister Matt Canavan will have new powers to “block exports” unless there are adequate supplies to meet Australia’s needs.

“It will ensure that the price of gas in Australia is at levels comparable to that in the international market because it is a global commodity,” Mr Turnbull told ABC radio.

“But what we’ve seen is because of these anticipated shortfalls, gas suppliers have been proposing contract prices which are really way too high.

“They are as much as four or five times the price per gigajoule, which is the metric, that are being offered in the United States.

“It’ll be cheaper than the prices that are being offered now, people are being offered prices of $20 a gigajoule, it should be around half that or less.”

While LNG exporters have contractual obligations they must meet, Turnbull also said that Australia’s free-trade agreements gave the government a right to protect local industry from gas shortages.

“They will not be able to export gas if that has the consequence of reducing the availability of gas for the Australian market,” Turnbull continued.

“This is a national interest matter, it is a short-term solution to a longer-term problem. The longer-term challenge that we face is we are not producing enough gas on the east coast — that is because of bans on gas exploration and development in Victoria above all and to a lesser extent in NSW.”

Hiked energy prices will force larger grocery bill, Woolworths warns

Rising energy costs will force the food giant Woolworths to hike its grocery prices, its CEO has warned. 

Speaking at a business forum in Melbourne, Brad Banducci said the company’s $360 million energy bill was increasing as the company placed a higher priority on its health foods. 

“We manage what we can manage with energy efficiency,” Banducci was quoted in an AFR report. “But given the cost increases that are coming through right now, we are trying to outrun a bear, but I am not sure we can.

“We will have to in some way, very cautiously and carefully, pass those through to our customers, unfortunately.”

“We are doing a lot of work on at the moment, and I just don’t know the answer right now. But it is a concern. It’s just a question of timing.”

A price hike due to energy cost would effectively end a long run of falling grocery prices in Australia, the report explained.

While research showed 60 per cent of shoppers want to buy healthier food, it tends to be fresher and requires chilling while organic foods are double the average cost of alternative products.

Banducci claimed that with a greater emphasis on healthier products, increased energy prices would eventually outweigh the company’s savings.

“We do need to make these products affordable,” Banducci continued, although he also added that, despite the high prices, increasing the number of “good for you” products had demonstrated a drive in sales.

“What we’ve been trying to address is that customers need products that are affordable and they need trust on price,” he said. “You are not seeing a profit shift from one side of the supply chain to the other.”

Energy prices, taxes threatening food sector jobs

High energy costs are putting pressure on food manufacturers and threatening jobs in the sector, according to the Australian Food and Grocery Council’s State of the Industry annual report.

The 2016 version of the report, to be released today, notes that employment in the sector has “hit a wall”, standing at 317,000 jobs. This total was 322,000 in the previous year.

Exports were up 14 per cent on the previous year, but operating costs were an issue, particularly with a shortage of gas supply contracts available, supermarket price wars, and in terms of taxation.

“Company tax cuts for all business are more important than ever as a means of sparking investment, and targeted investment allow­ances must also be considered,’’ Gary Dawson, the AFGC’s chief executive told The Australian, urging the opposition to pass a proposed tax cut for companies with revenues over $10 million.

Dawson said that gas price rises of up to 95 per cent were being seen in Victoria and NSW. The states had abundant gas reserves, yet bans on unconventional gas extraction.

“We have the crazy situation where cheap ­energy should be a source of comparative advantage for Australia but instead gas and electricity price increases are putting us at a disadvantage,” said Dawson.

The 2015-2016 report is in contrast with last year’s release, which found over 3,000 jobs created in the period, a “spectacular” surge in trade with exports up 28 per cent, and “double-digit growth across a whole range of categories.”

 

A 4 step guide to smart energy management

Having the right energy strategy can improve reliability and sustainability while reducing energy bills as Nicolas Larue reports.

Energy is typically the fastest growing expense for manufacturers today. It can consume up to 30 per cent of an operating budget. With digitisation and the use of electronic devices on the rise, the reliance on and use of energy will only continue.

As energy prices soar and green tariffs come into force, it comes as no surprise that manufacturers are concerned about how much energy they’re consuming and at what cost.

The benefits of effective energy management are clear: protect the environment, save energy and reduce costs, and ultimately operate a cleaner network free of power quality issues. But realising the full potential of energy savings in your business can be more complex than switching equipment off when it’s not in use.

With this in mind, here are four simple steps you can take to develop an action plan for smarter energy management that could see the energy bills in your facility drop dramatically.

1. Know your energy usage

Knowledge is power, so before diving in and installing technology within your facility, it’s important to get to know your energy usage.

Smart energy management provides visibility of effective and efficiency energy usage. So a good way to start is to conduct an energy and power audit. This is where you analyse energy use and power quality based on measurement and then establish a baseline – based on historical data from the last 12 – 24 months.

There are tools you can use to help measure your energy consumption, such as energy meters and power quality monitors. This review can be complemented by using a software platform that functions as a centralised portal of energy data – helping you to see all your areas of energy consumption and track in real-time.

Once you understand your usage, you can identify areas of significant energy use and those with poor power quality, and prioritise and record opportunities for improving energy performance.

2. Fix the basics

Once you understand where your energy is being used, implementing the right kind of corrective action can create an almost immediate financial benefit – potentially 10 – 15 per cent worth of savings. Here are just some of the opportunities for smarter energy management – where you could uncover efficiency gains:

Building controls: Simple control adjustments can produce rapid energy savings. Are your building controls optimised for performance? Are lights and other systems running at the correct settings?

Mechanical: How do HVAC systems use energy throughout the facility? Can the performance of chill water, distribution, and steam systems be improved? Do air handlers and sequencers need upgrading or adjusting? Are outdated motors wasting energy? Replacing an old motor with a newer, high efficiency motor can improve energy efficiency by 90 per cent.

Electrical: How is electricity used and how efficient is the total system—from lighting and controls to office equipment, refrigeration, and kitchens? Since facilities use electricity in many ways, there are usually opportunities for savings. There could be issues with power quality to address, such as high kVA demand, poor power factor, harmonic distortions and voltage sag/swell.

Envelope: How does your building envelope perform and how does it affect other energy systems? Could simple improvements to insulation yield significant savings?

Water: Water, like energy, is a resource that can be conserved to save money. Are cooling towers losing too much water to evaporation? Are you paying for sewage charges that could be avoided with metering? Can water heating be planned and managed to reduce costs, based on actual usage times and areas?

3. Automate energy solutions

Once you’ve fixed the basics, and implemented energy saving techniques, the next step is to, where possible; introduce automation across your energy efficient solutions.

Automation of your energy related appliances and facilities – whereby energy is only ‘on’ when it’s really needed – can add another 5 per cent of efficiency savings.

For example, you could have introduced energy saving light fittings – but if you further implemented ceiling mounted occupancy sensors and power linked intelligent lighting panels, you could see additional saving.

4. Don’t stop there

Without ongoing monitoring and maintenance you could see energy savings slip back by 2 – 8 per cent.

The final step is to keep regulating your energy usage and illustrate the positive impacts to keep energy management high on the business agenda.

This will also allow you to keep an eye out for new opportunities to make improvements as your facility changes and grows.

Burra Foods’ halves energy costs

Australian dairy ingredient processor Burra Foods recently halved their energy costs by installing a new wastewater treatment system.

According to Burra Foods’ Wastewater Treatment Plant Supervisor Daniel Tsivoulidis, they began to see results at the Korumburra site in the South Gippsland region of Victoria just one week after installing the Hydroflux HyDAF Dissolved Air Flotation unit.

“Within a week we were already removing so many of the solids in primary treatment that our secondary treatment Sequencing Batch Reactors did not need as much oxygen. We immediately saw a drop in electricity costs.

“With some more fine tuning we saw even more improvements.  We reduced our energy costs by almost half and the sequencing batch reactors can now process double the volume of water,” he said.

Burra Foods HyDAF unit now removes 60 to 70 per cent of contaminants in a continuous automated process and it has shown savings through reduced energy and chemical demand, as well as a reduction in operational expenses in downstream treatment.

The DAF unit also enabled improved pH fine-tuning and there is less down time now required for washing the microfiltration and reverse osmosis plants that form part of downstream processes.

The Burra Foods site can use up to a million litres of water a day and final treated water is discharged to the environment. Improved primary treatment reduces water variations going into the secondary and tertiary treatment further guaranteeing the high quality of this discharged water.

 

Tartar products maker turns to bioenergy, saves $2 m in a year on gas

Australian Tartaric Products grape waste-powered biomass
reactor has saved the company over $2 million in power bills so far, according
to the company.

BRW reports that the reactor, which is fueled by winemaking
waste products – including grape marc (skins and pips), which was previously used as
compost – was completed last year at a cost of around $10 million.

ATP chairman Malcolm Taylor said that feasibility studies
began in 2008 as rising gas prices began to bite. Plans were put on hold due to
the Global Financial Crisis, but by 2011 it was important that action be taken.

“As the cost of gas went up and up, the cost of production
was going up and squeezing the margin considerably,” Taylor told BRW.

“All the indications were that it was going to potentially
become uneconomic to produce.”

The investment was assisted by grants worth $1.7 million from the federal government and $1.8 million from the Victorian government.

According to the company, in its first year of operation the
biomass reactor has saved around $2 million in gas costs as well as producing
60 per cent of the ATP’s electricity.

The Colignan (near Mildura) plant in north-west Victoria has
operated since 1991 and makes natural tartaric acid, natural cream of tartar and food grade spirit, supplied to the wine industry.
