Top-fermented, medium-bodied, dry and well-hopped dark beer with a pronounced bitterness. They are robust beers and can sometimes be sweet. Porter was the most dominant style in Britain particularly during the industrial revolution of the 18th and 19th century. Today, the style is making a comeback after falling out of fashion and almost being lost. Back or chocolate malt gives Porter its dark brown, almost black colour. They are heavily malted and contain rich, roasted, malty flavours. They are similar but lighter in flavour than Stout.
