Ales are fermented with the ‘S. cerevisiae’ variety of yeast, at temperatures higher than lagers, typically between 55 and 75 F. The higher fermentation temperature of ales tends to produce beers with a more complex, fruity flavor, usually derived from [[ester|esters]] produced by the yeast during fermentation. Common varieties of ales include Pale Ale, Stout and Porter. | Ales are fermented with the ‘S. cerevisiae’ variety of yeast, at temperatures higher than lagers, typically between 55 and 75 F.
