Fermentation

• In the Tun Room, the sugar solution (WORT) is fermented by yeast into a weak alcohol solution called 'WASH'.

                                     

The vessels in the Tun Room are called 'Washbacks'.The distillery has the capacity to ferment 12 million litres of wash at any one time.Each washback has to be sterilised before it is used.  This is carried out by spraying the inside of the vessel with hot caustic soda. Fermentation lasts for at least 72 hours, and at the end of that time, the alcohol concentration in the wash is about >8%. Carbon Dioxide gas (CO2) produced during fermentation is routed to the CO2 recovery plant for processing.
