/* Yeast Types */
===Yeast Types===
Yeasts come in two basic types - top fermenting ale yeast and bottom fermenting lager yeasts. Of the two, ale yeast are most commonly used for homebrewing because they it can be fermented at room temperature.
* '''Top Fermenting Yeast''' - Commonly called ''ale yeast'' are fermented at or just below room temperature (10-25 C). These yeasts rise during fermentation and form a foamy head at the top of the fermentation vessel. They also produce a strong estery flavor that is a key characteristic of ales. Stouts, Porters and all forms of Ale are made with top fermenting yeast.
* '''Bottom Fermenting Yeast''' - Called ''lager yeast'' is fermented at low temperatures in the range of 7-15 C. Lager yeast grows slowly and tends to settle at the bottom of the fermenter because of the cold temperature. Bocks, Pilsners, Marzens and the large popular American lagers are made with this type of yeast.
