Beer gravity is certainly not one of the best well-known aspects of beer. I would argue, however, that it’s one of the most important aspects. Some people, and indeed most craft beer lovers, are familiar with a few beers of different strengths. Knowing these different strengths, you are already aware of the effects of gravity and what the change in gravity reaps, even if you don’t know that you know that yet. So let’s collectively extend our beer knowledge to what brewers mean by gravity.
