Adnams First Rate Gin has a base of English barley, wheat and oat. As opposed to their traditional distilled gin, Adnams uses 13 (yes, 13) botanicals instead of 6 in the formation of its intriguing new entry into the gin marketplace. Additionally, it is bottled at a stiffer 96 proof as opposed to 80. They are a "grain to glass" distiller, making small batches of gin in a traditional copper pot still.

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.
