“High-gravity” refers to brewing a beer with high original gravity (OG)—typically, above 1.075 OG is considered high. OG is a measure of the fermentable and un-fermentable substances in the wort before fermentation. read more
Low vs. high gravity beers The difference between the original gravity of the wort and the final gravity of the beer is an indication of how much sugar has been turned into alcohol. The bigger the difference, the greater the amount of alcohol present and hence the stronger the beer. read more
Sure a beer with a high abv can be thin but that does not mean it is low gravity. If a beer is 8-10% the original gravity is going to be fairly high. Final gravity should play a much smaller part in this conversation. read more
