Does the term “high fermentation” imply that a beer is stronger in degrees of alcohol?
High fermentation generally refers to teh temperature at which the beer is fermmented. “High fermentation takes places at a temperature varying between 15 and 25 C whereas low fermentation takes place at a temperature varying between 0 and 14 C. In the United States and Great Britain, the words “high fermentation” are generally associated with the word “ale” whereas low fermentation is associated with the word “lager”.” http://www.unibroue.com/brewery/fermentation.cfm Different yeasts may also be used: “It is not only the temperature difference that distinguishes the high and low fermentation beers; the yeast used also varies.” Different filtration is also used on some high fermentation beers.
