How to read a hydrometer

View your hydrometer floating in the juice sample at eye level.  The balling scale is the brix or sugar percentage.  In addition to the balling scale, a triple scale hydrometer offers a scale for specific gravity and for potential alcohol. 

Reading a +5-5 hydrometer: If the reading is below a (negative) -1.5 degrees or -2 degrees, then the wine is dry.  If the hydrometer is higher than a (negative) -1.5, such as a 0 reading or a plus 1 degrees, then there is residual sugar and one may attempt to restart.  To restart go to Lessons and read about stuck wine.

Fermtech Wine Thief Instructions.  This is a slick item for testing.  It is 19" long, plastic, and allows for you to pull a sample, drop in the hydrometer, take the reading and release the sample back into the carboy.
