Planning a craft distillery in India
The still is the photogenic part. The parts that decide whether a craft distillery survives are licensing, effluent, warehousing and the years of cash a whisky ties up before anyone can buy it.
Start with the product, then the cash
Decide what you will sell in year one, not just what you dream of selling in year five. Whisky has to sit in wood before it can be sold as whisky. Every litre in a cask is money you cannot spend. Most craft distilleries cover that gap with unaged or lightly aged spirits: gin, vodka or flavoured spirits that can be sold within weeks.
Model the cash before the kit. Write down how many casks you will fill each year, how long they will age and what you will sell meanwhile. In consulting work we often see founders size the stills well and the working capital badly.
The licensing path, at process level
Distilling is regulated more tightly than brewing. The broad sequence in most states is similar, though the details vary by state and change:
- Land, zoning and the in-principle approval from the state excise department.
- Environmental and pollution-control consents, usually through the state pollution control board.
- Building and equipment approval, then inspection before you are allowed to run.
- The distillery licence itself, bonded warehouse approval and brand and label registration before sale.
Excise officers will expect registers for every stage: grain or sugar received, wash made, spirit produced, casks filled and spirit released. Work with a licensing adviser who has handled distilleries, not only bars. Check the current notification for your state.
Plan the effluent before the stills
A distillery produces a lot of hot, acidic, high-strength waste. Spent wash or stillage is the residue left in the still after distillation. Its organic load is far higher than brewery wastewater. Regulators look hard at it. In many places they expect very little or nothing to leave the site as liquid.
Decide early how you will handle it: drying for animal feed, anaerobic digestion, evaporation or a contract with someone who takes it away. This decision drives site size, utilities and cost, so it belongs in the first plan, not the last.
Choosing stills and the rest of the kit
A typical small malt spirit set-up runs from mash tun to fermenters to a wash still, then a spirit still. Some craft producers choose a hybrid pot still with a rectifying column, which can make both a heavier malt spirit and a near-neutral base for gin from one unit.
- Copper. Copper contact removes sulphur compounds from the spirit. All-stainless stills tend to give a sulphury spirit.
- Steam. Most stills are steam heated, which means a boiler with registration and periodic inspection.
- Cooling water. Condensers need a lot of it. In an Indian summer the incoming water may be above 30 °C, so size the cooling tower or chiller for May, not December.
Water, grain and utilities
A distillery uses water for mashing, reduction, cleaning and above all cooling. Check the supply in the dry months before you sign for the land. Test it. Borewell water can carry hardness and iron that matter for mashing, while the water used to reduce spirit to bottling strength has to be very clean, usually demineralised, or the spirit can turn hazy.
Decide your raw material early too. Malted barley gives malt spirit, while other grains or sugar sources give different spirits and may fall under different rules. Secure a supplier who can give you a consistent specification year round, because a change in malt shows up in your yield and your spirit.
Warehousing in Indian heat
Casks lose spirit to evaporation, the angel's share. Scotland's figure is commonly quoted at around 2% a year. In hot Indian conditions losses run much higher. The spirit also extracts from the wood faster. That is a cost and a style decision at once. You may get mature character in fewer years, but you lose more volume getting there.
Your warehouse needs security, excise oversight and a cask record that ties every cask to its fill date, strength and volume. Build that record from day one.
The numbers to model
- Spirit yield: litres of pure alcohol per tonne of malt or grain. Track it from the first run.
- Cost per litre of pure alcohol, before and after ageing losses.
- Utilities: steam, cooling water and power per run.
- Effluent volume per litre of spirit and what it costs to handle.
- Working capital tied up in casks, by year.
If you already run a brewery, your brewhouse skills carry over to mashing and fermentation. Distillation, cut points and warehouse control are new. Our guide on getting new make spirit right covers the still side.
Common questions
How long before a craft distillery can sell whisky?
Whisky must age in wood before it can be sold as whisky. The minimum depends on the market's rules. Most craft distilleries sell gin, vodka or other unaged spirits in the meantime.
What is spent wash?
The liquid residue left in the still after distillation. It has a very high organic load, so handling it is a major part of planning a distillery.
Why do Indian warehouses lose more spirit?
Heat drives faster evaporation from casks than in cooler climates like Scotland. It also speeds up extraction from the wood, so flavour develops faster too.
