Stout

Stout is a type of dark beer that is generally warm fermented, such as dry stout, oatmeal stout, milk stout and imperial stout.

The first known use of the word "stout" for beer is in a document dated 1677 in the Egerton Manuscripts, referring to its strength. Porters were brewed to a variety of strengths, with the stronger beers called "stout porters". The history and development of stout and porter are thus intertwined. Provided by Wikipedia
