Corn sugar, a.k.a. dextrose or priming sugar is the classic sugar used in priming beer and gives consistent carbonation without greatly affecting flavor. Use it at a rate of 1 oz. per gallon of beer (or 5 oz. per 5 gallon batch, about 3/4 cup) to prime beer for bottling. It can also be used to add fermentables to beer, wine, cider, or any of your favorite imbibements. Corn sugar tends to lighten body and dry out beers, so it can be used to up alcohol content in lighter-colored beer styles such as cream ales, pale ales and IPAs without adding to body or mouthfeel.
