Corn sugar is an inexpensive, 100% fermentable sugar that produces alcohol without leaving the cloying residual sweetness of malt extract. Intended for beer, wine, cider, and meads.
Adding roughly 3.4 ounces of Corn Sugar per gallon will boost ABV by 1%
Their use in quantities of 30-40% will produce a beer with a considerably lighter body than one brewed strictly with malt sugars (think American light lagers).
