What is a Yeast Brink?

A yeast brink is a stainless steel keg that has been modified to collect yeast from a conical fermenter to be saved, and pitched again into a new batch of beer. The yeast brink has a 4 inch Tri Clamp port on top instead of a standard ball valve, as well as a 1.5 inch Tri Clamp port on the sidewall near the bottom.

Collecting Yeast

To ensure optimum quality, brewers recommend thoroughly sanitizing the yeast brink and parts between every batch. Usually, depending on the volume of yeast, it is advisable to run off the first few gallons of yeast slurry that first flocculated to the bottom. This yeast is the least vital and would not be ideal for re-pitching. The number of generations that may be re-pitched is dependent on the strain, but over reusing may result in mutations that may eventually change the desired fermentation characteristics of the yeast strain.
