How much corn sugar should I use for a kegged batch?
Use 3 ounces in 5 gallons by weight. This is approximately ½ a cup, but it is best to weigh it out, and corn sugar can vary in bulk from lot to lot, and over carbonation can be dangerous, and lead to personal injury. Always make sure the beer has finished fermenting before bottling by properly using a hydrometer. For a single 1.3 gallon mini keg or Tap A Draft Bottle, use ¾ of an ounce per keg by weight.
