If you're into home winemaking, you know that you need the best wine equipment around. At E.C. Kraus, we take our winemaking and wine hydrometers seriously. You need a wine hydrometer in order to know what percentage of alcohol your wine has, the sugar content of the wine, and the wine's specific gravity. We have wine hydrometers that also read Brix or Balling scales. A must for any winemaker, hydrometers are a necessary part of your winemaking toolkit.
