Avoid leaving water or moisture on the refractometer since it could leak into the machine and make it inaccurate in future readings. To find the exact weight of the alcohol content, use a calculator to enter the equations final estimated specific gravity. When the sugars are converted to alcohol during fermentation, the hydrometer will sink further. To figure out the alcohol content of our homebrew, we need a way to measure the sugars at the beginning of brewing and at the very end. % of people told us that this article helped them. Once again, this is only an approximation, and loses accuracy as the alcohol content goes up. Modern distilleries are outfitted with state-of-the-art digital alcohol meters, which are replacing their analog devices. Poor sanitization is one of the most common ways to ruin a beer batch.

Well look at the different ways of measuring the alcohol percentages in common beverages. Different kinds of drinks may contain the same amount of alcohol but have very different ABVs because of their serving sizes. Despite the fact that they may be less precise, they allow you to use fewer samples than in the past. All tip submissions are carefully reviewed before being published. ..

A standard drink in the U.S contains about 14 grams of pure alcohol, according to the Centers for Disease Control and Prevention. As a result, density and alcohol measurements will be distorted. Here we take a standard sample (say 250ml) and distil it. In unfermented wort, a Specific Gravity of 1.055 is usually required. We always recommend that wine should be fermented down to dryness and should you like a sweeter wine then add sugar or grape juice at the end to reach your preference in sweetness.
