Adnams Copper House vodka is made from a base of East Anglian barley (which a quick Google search reveals as an eastern, seashore area of England owing its name to the Angles). They are a "grain to glass" distiller, making small batches of vodka in a traditional copper pot still. The spirit starts as a beer and undergoes two distillations to result in what they regard as a vodka with a "subtle butterscotch note." They suggest serving with tonic and a lemon garnish or in a Bloody Mary cocktail.
Adnams Copper House Distiller was founded in 2010 by Jonathan Adnams whose prior background included brewing. They use small batch distillation methods, which they regard as superior in being able to produce purer spirits (by this, we take it to mean isolate ethanol away from other more foul-tasting methyl and aldehydes). They use "east Anglican malted cereals" as the base for their spirits, which our locally grown for the distillery. Part of their distillation process includes a first run of 7% "beer" that ferments from their own brewery's yeast approaching a century in use.
