How the bulk whisky trade works

Whisky is traded before it is bottled

Whisky takes years to mature, so distilleries and brand owners trade it at every stage. They trade new make spirit straight off the still. They trade filled casks that are still ageing. They also trade finished whisky shipped in bulk tanks to be bottled somewhere else. Blenders need many different whiskies and no single distillery makes them all, so swapping and buying stock has been normal for well over a century.

For a desk in Bengaluru, that means the number in an inventory system is often a promise about whisky still sleeping in a warehouse thousands of kilometres away.

The units that matter

Bulk whisky is priced and tracked in litres of pure alcohol (LPA), not in litres of liquid. Pure alcohol is the volume multiplied by the strength. A 200 litre cask at 63.5% ABV holds 127 litres of pure alcohol. When that cask is checked again after a few years, the figure is lower, because some spirit evaporates through the wood. Checking it again is called regauging.

In Scotland the commonly quoted evaporation loss is around 2% a year. In hot climates such as much of India the loss is well above that. Our guide to whisky trade marketing covers the other end of the chain, where that liquid finally reaches a glass.

New make, filled casks and finished bulk

Three products move in the trade and they behave differently on a spreadsheet:

• New make is spirit straight off the still, usually traded at or near filling strength, commonly 63.5% ABV in Scotland. It is the cheapest per litre of pure alcohol but needs years of warehousing.
• Filled casks are casks already ageing. Price depends on age, cask type, distillery and the regauged contents.
• Finished bulk is matured whisky, often blended, sold by the tanker for reduction and bottling.

A cask bought at three years old and sold at eight has carried five years of storage fees, insurance and evaporation loss. Anyone modelling margin on aged stock needs all three in the sum, not only the purchase price.

Who does what in the trade

• Distilleries make new make and either keep it for their own brands or sell it.
• Blenders and brand owners buy spirit and casks to build consistent blends year after year.
• Brokers match buyers and sellers, often handling sample tasting, paperwork and transfer of ownership.
• Bonded warehouses store casks with duty unpaid until the whisky leaves for bottling or sale.
• Bottlers reduce, filter and bottle bulk whisky, sometimes in another country.

Ownership of a cask sitting in a warehouse is usually recorded on paper. The cask itself may never move until it is emptied.

Why Scotch arrives in India in bulk

A great deal of Scotch leaves Scotland in tankers rather than bottles. Bulk shipping is cheaper per litre of pure alcohol. It also lets the whisky be reduced and bottled near the market. In India, imported bulk Scotch is often blended with Indian spirit to make whiskies bottled in India. Single malt Scotch is the exception: under the Scotch whisky rules it must be bottled in Scotland.

That is why a planner may see two very different supply chains in the same portfolio. One is cases of bottled single malt arriving by container. The other is bulk whisky arriving by the tanker load to feed a local bottling line.

What it means for forecasts and cost

Whisky stock is laid down years before it is sold. The whisky in a ten year old blend was filled into casks a decade ago, based on a forecast nobody at the company may still remember. Too little laid down means a shortage that cannot be fixed quickly. Too much ties up cash in warehouses for years.

Bulk prices move with that cycle. When aged stock is scarce, prices for older casks rise. When distilleries have expanded and new make is plentiful, prices fall. Teams that understand this read their cost and stock numbers far better.

A note on cask investment

Private cask investment schemes have grown in recent years. Some are legitimate. Others overstate returns or sell casks that are hard to resell. Staff should know the basics: who holds title, which bonded warehouse stores the cask, how regauging and storage fees work and how the cask could actually be sold.

Your first step: ask your supply or finance team to show you one line of bulk whisky stock in the system. Find out its litres of pure alcohol, fill date and warehouse.

Common questions

What is bulk whisky?

Whisky sold as new make, in casks or in bulk tanks rather than in bottles. It is usually traded between distilleries, blenders and bottlers.

What does LPA mean?

Litres of pure alcohol: the liquid volume multiplied by its strength. It is the standard unit for pricing and tracking bulk spirit.

Can single malt Scotch be shipped in bulk?

Not for bottling abroad. Under the Scotch whisky rules single malt Scotch must be bottled in Scotland. Blended Scotch can be shipped in bulk.
