 Raw materials   (Site not responding. Last check: 2007-11-02)
The top-fermented yeast is active in a temperature range from 15 to 25°C. During fermentation, the yeast cells rise to the top - hence, top-fermented - and form a layer on the surface of the wort (referred to as "krausen" by the experts).
In contrast to top-fermented yeast, over time the bottom-fermented yeast settles at the bottom of the fermenting vessel - hence, bottom-fermented - where it can be easily harvested.
Bottom-fermented yeast is active within a temperature range from 5 to 9°C. This fermentation leads to a more thoroughly fermented, potentially drier, cleaner and rounder beer.
