RVA Yeast Labs provides the freshest brewing yeast and souring bacteria to breweries, wineries and homebrewers in Virginia and beyond.

With a masters of science in chemical ecology and experience teaching biology, founder Malachy McKenna’s attention to the scientific aspect of brewing was inevitable. 

Since 2013, McKenna has used his expertise in brewing and science to offer brewers the freshest yeast for optimal fermentation.

RVA Yeast Labs is located near Richmond, Virginia.  An area affectionately referred to as “RVA” and home to a growing beer destination and community.
