Additional Notes:
Traditional examples often display persistent head retention.Small amounts of wheat can be used in brewing beers of this style. Koelsch-style beers are fermented at warmer temperatures than is typical for lagers, but at lower temperatures than most English and Belgian-style ales. They are aged cold. Ale yeast is used for fermentation. Lager yeast is sometimes used for bottle conditioning or final cold conditioning.
