Ales are brewed with top-fermenting yeast which allows for rapid fermentation at warmer temperatures; Lagers are brewed with bottom-fermenting yeast which ferments more slowly and at colder temperatures. Lagers – Lager means to store or put aside. – This beer is made with bottom yeast, so-called because it flocculates to the bottom of the vat. – Traditionally bottom yeast will ferment at cold temperatures less than 10 deg C. Now fermentation takes place at 12 to 18 deg C. This cold or deep fermentation allows the malt and hops to assert their fine flavours. – Lager tends to be paler, drier and less alcoholic than ales. – Pilsener or pils beer originated in Bohemia where brewers first found beer that was over-wintered or lagered improved if stor
