The Tun Room

The liquid wort is pumped into six massive Oregon pine tubs, called washbacks, where yeast is added and all-important fermentation begins. The yeast feeds on the sugar, converting it naturally into alcohol. The resulting alcoholic liquid, which is like a strong malty beer, is called 'wash'.

  • Each washback holds 40,000 litres of wort and is named after a previous distillery owner, starting with Mr Simson who established Bowmore back in 1779.
  • We add 100kg of yeast to each washback.
  • Once properly underway, fermentation causes the wash to bubble and froth vigorously.
  • Fermentation takes 48 hours and the resultant wash has an ABV of 7.5-8%.
