Stout is a dark, top-fermented beer with a number of variations, including dry stout, oatmeal stout, milk stout, and imperial stout. The first known use of the word stout for beer was in a document dated 1677 found in the Egerton Manuscripts, the sense being that a “stout beer” was a strong beer, not a dark beer.
