Hello. How do you measure the alchohol content of homebrew? thanks in advance.
Do you actually use that over the hydrometer?david_42 said:If you really want to know: purchase a heat-resistant 100 ml graduate cylinder and a good thermometer. Place EXACTLY 100 ml of ale in the cylinder (noting original temperature) and heat in a water bath until the ale reaches 78C. At this point, the alcohol will start to boil off and the temperature will stay at 78C until almost all of the alcohol is gone. When the temperature starts rising again, cool the cylinder to the original ale temperature (so the water shrinks to its original volume). Read the level and subtract from 100. That's your ABV.
If you have a really good scale, you can measure the weight change.

A. I don't really care about ABV
B. I'm too lazy to do this routinely. I did it on my first cider because the gravity was under 0.990 and I didn't believe it: 8.5% from fresh pressed cider!
