This page will help you do some common winemaking conversions.

Figure the alcoholic content of your wine, where starting and ending specific gravity readings are known. Be sure to measure starting S.G. before you pitch the yeast!.

Starting S.G.		Select temperature of must (°F) when sample was taken:

Ending S.G.		Select temperature of must (°F) when sample was taken:
