How To Read A Hydrometer.

By taking a specific gravity reading before the introduction of your yeast to the must, then again when fermentation is complete can you determine the alcohol percentage by volume. Subtract the final reading from the beginning to get your answer.

When your hydrometer stops declining for 3 days in a row can you be certain that fermentation has ceased.

Hydrometers can contain any or all of the following scales, specific gravity, % of alcohol by vol., pounds/ounces of sugar per gallon and temperature.

People say how fast time flies when you are engaged. Just wait till your married. See how fast it flies then.

I just got my first set of hydrometers. There are three, they are made of glass, measure alcohol percentage, and have scales of 0-40, 40-70, and 70-100, respectively.

I've done a little home brewing from kits in the distant past, and recently decided on a whim I'd get back into it. No kits, but I have three batches of country wine and one of beer in progress. The fermentation of two appeared complete and have been racked.

Never used a hydrometer before. Can someone please advise on a minimal-mess, sanitary, efficient methodology?

Here is a good video to give a visual:

To know how to say what other people only think is what makes men poets and sages; and to dare to say what others only dare to think, makes men martyrs or reformers, or both. Elizabeth Rundle Charles, writer (1828-1896)
