Ale is made from light-colored malt usually, hops are used to give it a bitter taste, and all of the sugar goes to alcohol, giving it an average of 6 per cent. alcohol. Porter is strong, dark ale really, the malt used being dried at a greater heat. Brown stout is stronger still, both porter and brown stout containing more of the carbohydrates extracted from the grains from which they are made than either ale or beer. In alcohol they are about equal to ale.
