The Ale is also called as surface or high fermentation yeast at room temperature up to 25° C. It is typically used for home and artisan brewing essentially. While using it rises to the surface during fermentation. The result is a beer with body, with some notes of fruit and pure flavor.
The Ale yeast is often used for the production of some known beers, such as Pale Ale, Porter, wheat beers… this type of yeast is more popular and traditional, and is the one used for centuries before the appearance of Lager.
