Scotch Malt Whisky Society Scotch Malt Whisky Society The Scotch Malt Whisky Society (SMWS), founded in Edinburgh in 1983, is a membership organisation which bottles and sells single cask, single malt whisky. It purchases individual casks from more than 125 malt whisky distilleries in Scotland and throughout the world, bottles them and retails directly to its members. It also runs three private members' rooms in the UK and in several international locations.

Whisky compound in sherry, and contributes fruitiness to the aroma. The diketone diacetyl (2,3-butanedione) has a buttery aroma and is present in almost all distilled beverages. Whiskies and cognacs typically contain more of this than vodkas, but significantly less than rums or brandies. Polysulfides and thiophenes enter whiskey through the distillation process and contribute to its roasted flavor. Whisky that has been aged in oak barrels absorbs substances from the wood. One of these is cis-3-methyl-4-octanolide, known as the "whisky lactone" or "quercus lactone", a compound with a strong coconut aroma. Commercially charred oaks are rich in phenolic compounds.
