Brix
From Distillers Wiki
One of several hydrometer or saccharometer scales denoting the density of liquid (must, juice or new wine) in terms of specific gravity. Each degree Brix is equavalent to 1 gram of sugar per 100 grams of liquid. The potential alcohol of a must is estimated by multiplying the Brix reading by 0.55. Both the Brix and Balling scales are comparable and are usually used to finely estimate sugar content.
