Hydrometers, Test Jars and The Fermtech Wine Thief

The hydrometer is the best test instrument that has happened to home winemaking.

The unit of measure most commonly used is Specific Gravity. (Potential Alcohol and Percent Sugar can also be measured)

Put the wine or must being tested into the included storage tube or one of our test jars with bases. Gently float the hydrometer in the liquid being tested and give it a quick spin to remove any air bubbles. The level at which the hydrometer floats will tell you how much sugar is in the liquid expressed as Specific Gravity. Water has a Specific Gravity reading of 1.000. Liquids that are more dense than water (grape juice with high sugar levels) will have higher Specific Gravity readings. Liquids that are less dense than water (alcohol) will have lower Specific Gravity readings. This information is very useful to the winemaker as it will indicate whether the starting sugar level is too high or too low and when fermentation is complete. The Potential Alcohol Scale will allow you to calculate the approximate alcohol content of the finished wine.
