Beer brewers classify yeasts as top-fermenting and bottom-fermenting This distinction was introduced by the Dane Emil Christian Hansen. Top-fermenting yeasts are so-called because they form a foam at the top of the wort during fermentation They can produce higher alcohol concentrations and prefer higher temperatures, producing fruitier ale-type beers. An example of a top-fermenting yeast is Saccharomyces cerevisiae, known to brewers as ale yeast. Bottom-fermenting yeasts are used to produce lager-type beers
