Performance is unparalleled with vigorous fermentation the rule rather than the exception. Yeast for five gallon batches are sold in 30 ml vials. One barrel (32 gallon) batches are sold in 200 ml bottles. We grow brewery scale custom pitchable batches as well.

Trust

RBY's main focus is to team up with creative fermenters. By giving brewers a low price point, no fault money back guarantee on all first pitches, and unparalleled brewer to brewer service, RBY strives to both supply and consult with craft beer customers, and instill trust and confidence in working with fermentations.

Quality

We make yeast from barley malt. We don't add chemicals, buffers or odd carbon sources. The theory is that natural growth media will induce enzymes necessary for vigorous fermentation of barley-based wort. Cell counts are published on each bottle to ensure proper pitching rate. Our yeast health is the best in the business.

Art

The art of brewing is combining non-living ingredients, and allowing those ingredients to ferment with living organisms. Because we are constantly brewing, RBY is intimately familiar with what makes fermentations "tick", which is marrying the physical fermentation parameters with the genetics of the fermenting organism. RBY has over 70 working strains to choose from, and we are constantly isolating and breeding new yeast and bacterial strains. The idea is make our customers the best, most artistic fermenters in the world.

Value

We believe that the quality of some craft beer is being held back because there is a perception that fresh pitches are too expensive. This leads to brewers to overuse, borrow re-pitches or use dry yeast for production. All of these "cheaper" alternatives lead to off-flavors because of the bacterial and wild yeast load, poor yeast health, low cell counts or poor quality.

Pure as the driven snow, RBY is healthy yeast!

Real Brewer's Yeast is about 2/3 the price of our competitors. Because RBY yeast is so pure, it stands up to multiple generations. We do not charge extra for bottles and local delivery (free in Southern California). Our bargain priced yeast allows breweries to buy extra yeast for high gravity beers, and change up strains more often for a broader product profile.
