Beer Fermentation

High Gravity Fermentations

High-gravity fermentations involve worts of up to 18°P and even higher (38). Following fermentation and maturation, the beer is diluted with cool carbonated water to a prescribed original gravity or to a prescribed alcohol concentration. There are a number of advantages associated with high-gravity brewing. Munroe reports that it results in beers that are more consistent (% alcohol, original gravity, etc.) and more physically stable since the compounds responsible for haze are more easily precipitated at higher concentrations.
