The concentration of alcohol in a beverage is usually stated as the percentage of alcohol by volume (ABV, the number of milliliters (ml) of pure ethanol in 100 ml of beverage) or as proof. In the United States, proof is twice the percentage of alcohol by volume at 60 degrees Fahrenheit (e.g. 80 proof = 40% ABV).

What can I use instead of a hydrometer?

10 Answers. Refractometers are about the only other reasonable alternative for the homebrewer. They are a little more expensive, but usually much easier to use. They only need a few drops of wort/beer to get a good measurement.
