Any stout with ice cream is a treat but chocolate is best. Ingredients for a typical chocolate stout include dark malt extract, two-row or Munich malt, crystal malt, and chocate malt which gives it the chocolate taste. Some brewers will use malt sugars or brown sugar but I prefer to stay with malts. Some brewers will add chocolate nibs for more chocolate flavor but syrup is too sweet. Usually has an alcohol content between 4.8 and 5.6 but an imperial can go to 9.4 as long as the alcohol doesn't overpower the flavor.
