Wheated Imperial Milk Stout with Coffee and Lactose. The original recipe for this decadent nightcap was a simple affair - vodka, espresso, and coffee liqueur, developed in the 1980s. We've taken a brewers spin on this classic cocktail by steeping soft, but rich, wheated imperial milk stout for 5 days on whole coffee beans, dry-hopping course ground Ethiopian espresso provided by our friends and roasters at Oddly Correct. The result is a smooth coffee-forward delectably full-bodied elegant way to end the perfect evening.
