What is flocculation?

Flocculation refers to the clumping of yeast cells at the end of fermentation. Strains are separated into three main degrees of flocculation- High, Medium, and Low.

An example of a highly flocculent strain would be our English Ale yeast, which will settle at the bottom of the fermentation tank. An example of a low flocculent strain would be our Hefeweizen yeast.
