John McCarthy, warned that a typical ‘wash’ of 30,000 litres would only create 2000 litres of low wines to develop into spirits.
‘One thing you need to think about is somewhere to put your waste (from the wash), as you need to throw away 28000 litres of liquid down the drain - so it’s not for everyone.’
Adnams put the remnants of the wash into an anaerobic digestion facility on-site, which produces gas and electricity from waste and feeds into the National Grid.
Emma Hibbert, corporate affairs manager at Adnams, said: ‘We’ve worked very hard to reduce our impact on the environment.’ ‘The digester is like a cow’s stomach. Product goes in and it gets churned up, and produces energy from product which would otherwise go to landfill.’
Adnams distillery, based in the firm’s Sole Bay Brewery in Southwold, includes the production of vodka, whisky, gin and absinthe.
