Recent Developments in High Gravity Brewing

The major advantage of high gravity brewing is that by reducing the amount of water in the mash,the production can be increased without expanding existing brewing, fermenting and storage facilities. Disadvantages include decreasing of brewhouse material efficiency and kettle hop utilization, reducing of foam stability,viability and vitality, variable reactions to acid washing, a requirement for adjustments in the wort divalent composition, and a need to reduce the number of yeast generation as the wort gravity grows.
