Porter Alternative is a term used to describe two types of beer: ALE and STOUT. ALE is a type of beer that is brewed using warm fermentation, which produces a sweet, full-bodied flavor. STOUT is a type of beer that is made with roasted malt or barley, giving it a dark color and a strong flavor. Both ALE and STOUT are popular alternatives to Porter, a type of beer that is made with dark malts and has a sweet, malty flavor.
