The Life of a Cask From Wine to Whisky

  1. An oak tree is cut down. Typically one tree is used to produce 2 standard 220 L (64 gal) barrels. The most popular oak choices are French and American oak although Hungarian and Russian oak can also be found.
  2. Building the cask. Coupers (cask-makers) build casks without glue.
  3. Toasting the oak. Heavy toast adds more vanilla and butter flavors.
  4. Wine ages in new barrels for 3-30+ years. Sherry production uses the ‘solera’ system, where new wine is placed in a sequential barrel chain. Wine is bottled from the last barrel in the solera and topped with the wine from the next sequential barrel. A 30 year solera can have 30 barrels.
  5. Used barrels are in high demand from Sherry producers. Whisky producers prefer barrels from dessert wines such as Sherry, Port and Sauternes. The most popular barrels for whisky production is from Oloroso Sherry barrels, a style of aged Sherry.
  6. From Sherry to Whisky. Sherry producers originally used a cask for up to 30 years. Today it’s more common to use a cask for 18-24 months before shipping it to Scotland.
  7. A Single malt Scotch cask ages 3-40+ years. A single cask may be used for up to 70 years.
