A quick and easy way to carbonate your beer! Add one of these carbonation drops to each 12 oz beer bottle, or two drops to a 22 oz bottle, while you're bottling your beer. These pre-measured lozenge shaped drops give you an exact amount of glucose and sucrose in you beer bottle. These drops are prefered by some homebrewers for the consistent, predictable levels of carbonation that they can achieve. They dissolve quickly and are easy to use.
