§1What this business is

Matured coconut water has about 3 per cent sugar. Sugar is added to raise it to 10 per cent, and yeast ferments it to alcohol in about 4 to 5 days. The clear liquid is siphoned off, mixed with mother vinegar and sprayed over corn cobs packed inside a vinegar generator, where bacteria turn the alcohol into acetic acid. The liquid is recycled until it reaches 4 per cent strength, then aged and bottled. The Coconut Development Board developed the method with CFTRI, Mysore. The vinegar is used as a preservative and flavouring in pickles, salads and sauces.

Capacity: 100 litres a day; 100 litres of coconut water gives 100 litres of vinegar.

§2Is it right for you?

Who it is for

A small processor next to copra, desiccated coconut or coconut oil units who can collect their coconut water daily.

Who it is not for

Someone who expects quick, large profits or has no nearby source of coconut water.

Advantages

  • Raw material is coconut water wasted by copra and desiccated coconut units
  • Natural vinegar is preferred over synthetic vinegar by pickle makers and exporters
  • Small outlay of ₹6.20 lakh besides land
  • Litre for litre yield: 100 litres of water gives 100 litres of vinegar

Drawbacks

  • Net profit of only ₹0.8 lakh a year at this size
  • Synthetic vinegar is much cheaper in the market
  • Fermentation and ageing tie up stock for weeks
  • Coconut water must be collected fresh every day

Skills you need

  • Running yeast and acetic fermentation
  • Testing acidity of each batch
  • Clean bottling and labelling
  • Selling to pickle units and food shops

Why difficulty 2/5: Low cost and simple equipment, but fermentation needs steady attention and margins are thin.

§3Market

Who buys

  • Pickle makers
  • Sauce, salad dressing and condiment makers
  • Households, hotels and restaurants

How it sells

  • Bulk supply to food processing units
  • Bottles through grocery shops and supermarkets
  • Online sale as natural vinegar

Good to know

  • The profile prints plant and machinery as one line of ₹2.5 lakh; item-wise costs are not printed.
  • Product specification in the profile: acidity 5.26–5.76 g per 100 ml as acetic acid, alcohol nil.
  • The profile says natural vinegar now has an export market in place of synthetic vinegar.

§6Schemes & subsidies

At ₹6.20 lakh the unit is well within PMEGP's ₹50 lakh ceiling for manufacturing, and PMFME supports micro food processing units. A MUDRA loan can cover the machinery. Also ask the Coconut Development Board, which holds the technology, about help under its Technology Mission on Coconut.

§7Money

How the investment is worked out: Building (roofed structure of 750 sq ft) ₹3.0 lakh + plant and machinery ₹2.5 lakh + preliminary and pre-operative expenses ₹0.25 lakh + contingencies ₹0.20 lakh + margin money for working capital ₹0.25 lakh = ₹6.20 lakh. The profile prints these lines without a total; they are added here. Land of 25 cents is extra — its cost is not printed.

Working capital: Margin money for working capital ₹0.25 lakh.

§8Export potential

Confirm the HS code in the DGFT ITC(HS) lookup before you export

2209Vinegar and substitutes for vinegar obtained from acetic acid

Export council / board: Coconut Development Board

  • The profile itself prints no HS code; 2209 is the customs heading for vinegar.

§9Risks — where people fail

  • Batches not reaching the required acidity
  • Contamination in the generator or storage drums
  • Irregular supply of coconut water
  • Price pressure from synthetic vinegar
