Estimating the amount of sugar converted to alcohol can help test alcohol content without hydrometer. The most common method for testing the alcohol level is by using a hydrometer. The initial specific gravity can be measured directly or from the Brix number from index of refraction measurement. Place the hydrometer on a flat, level surface, and gently spin the hydrometer back and forth to release any bubbles that may have formed on its surface. You can determine the amount of alcohol in the finished beer by measuring the density before and after fermentation.
