Corn sugar and table sugar (sucrose) are cheap fermentable sugars that product alcohol without leaving the cloying residual sweetness of malt extract. Adding a small amount (no more than 10 percent of total fermentable) will increase alcohol content with minimal impact on taste. Their use in quantities of 30 – 40 percent will produce a beer with a considerably lighter Body than one brewed stickily with malt sugars (Think American light lagers). any canned kits, and the Body of the beer they produce, can be improved upon greatly by substituting the Corn sugar with malt extract, either dried or liquid. Bottling beer: use 3/4 cup of Corn sugar (priming sugar), mini keg: use 1/3 cup of Corn sugar (priming sugar).
