What is a Stout?
Stout is a dark beer made using roasted malt or roasted barley, hops, water and yeast. Stouts were traditionally the generic term for the strongest or stoutest porters, typically 7% or 8%, produced by a brewery. There are a number of variations including Baltic porter, dry stout and imperial stout. Some popular stouts are: Guinness, Donnybrook Stout, Yeti Imperial Stout, Black Chocolate Stout and Darkness Stout
What is a Porter Beer?
Porter is a dark, almost black, fruity-dry, top fermenting style. An ale, porter is brewed with a combination of roasted malt to impart flavor, color and aroma.
So is there any difference?
Yes, there are certainly differences between porters and stouts, but is there enough for the average beer drinker to notice … or care? Perhaps Beer Is My Church is right in suggesting the two are interchangeable. However, there is certainly enough subtle difference in the construction of each beer that a craft beer lover may pick up.
