LAGER

Lager is a form of beer in which the fermentation takes place at a lower temperature than does when producing an ale, and after fermenting the beer is stored at a sub-zero temperature (a process known as lagering, hence the name 'lager') - typically minus one degree - for between fourteen and ninety days, depending upon the quality of the beer being produced. Lager was developed in central Europe during the Middle Ages by monks and spread to the rest of the world, arriving in Britain first at the time of the Industrial Revolution, but not becoming widely popular until the 1960's and in 1986 finally over taking ale as the most popular form of beer consumed.
