🥃 Sherry butt
A sherry butt is an oak cask of about 500 litres that once held sherry and now matures whisky; it gives a darker colour and notes of dried fruit.
A sherry butt is the cask behind many sherried single malts and blends: an oak cask of about 500 litres in which sherry was once matured or transported and which now matures whisky. Such a cask gives the spirit a darker colour and notes of dried fruit, nuts and spices. Scotch has long been matured in casks that held sherry, so this style is still considered classic.
Size. A butt is usually reckoned at 475-500 litres; in the sherry bodegas a butt holds 600-663 litres. The Scotch Whisky Regulations 2009 require maturation in oak casks of no more than 700 litres, so a butt is well within the limit. The term denotes the shape and volume, not the drink inside.
History. According to the Consejo Regulador, until the 1970s sherry was shipped to Britain in export butts, and the empty casks went to whisky producers. Today such casks are made specially: a cask is filled with sherry for 12 to 36 months and then sent to Scottish distilleries. These casks have their own features: the wood gives tannin, and the remains of the wine give sweetness.
Oak. European oak is used more often, sometimes American oak; producers do not always disclose the origin of the wood. This cask should not be confused with a "sherry cask finish", where the whisky only matures in a sherry cask at the end.
Why this matters to you. "Sherry" on a label describes the cask, not the sweetness of the drink or its quality. The WHO reminds us that there is no safe level of alcohol consumption.
