Beers are broadly divided into two categories: top-fermented ales and bottom-fermented lagers. Stouts are a type of ale that uses slow-fermenting yeast that evolved out of the porter style. Stouts tend to be thicker, darker, opaque beers with higher specific gravity - similar to milk. They are usually less bitter than other ales, and typically exhibit tones like chocolate, coffee, oatmeal, and milk.
