The formula for calculating the alcohol content of beer is shown below. For example, if the OG is 1.090 and the PAV is 0.990, the AAV is 10%. Slowly insert the hydrometer to prevent it from falling. Following this process, the remaining alcohol is purified and concentrated, resulting in the final spirit. Testing for alcohol content is an important part of home-brewing to determine the potency of your drinks. Additionally, certain types of food can cause a false positive. The easiest way to know how much alcohol is in your wine is to take two readings with what's known as a wine hydrometer: one reading is taken before the fermentation has started and the other reading is taken after the fermentation has finished. During fermentation, the hydrometer is calibrated to the density of water. Typically, one can calculate this from the initial and final specific gravity. Estimating the amount of sugar converted to alcohol can help test alcohol content without hydrometer. The initial specific gravity can be measured directly or from the Brix number from index of refraction measurement. When there is more alcohol in a liquid, its density decreases, resulting in a slightly lower alcoholmeter reading. A refractometer can be used to measure the alcohol content of unfermented wort by simply taking a Brix reading and repeating it after fermentation is complete. So, next time you pick up a bottle of wine or a six-pack of beer, youll know how the ABV percentage is measured and what it means. For an approximate estimation, the magic number is 131.25.
