Our mission is simple: Provide commercially unavailable or rare yeast and bacteria strains to the homebrewing and craft brewing communities in high quality liquid culture. 

Here at The Yeast Bay, we're all about adding value to the homebrewing and craft brewing communities by providing a rich diversity of organisms brewers can use to serve as the bridge between the wort they produce and the beer it's transformed into. One of our primary goals is to help brewers big and small develop new, unique sensory experiences for beer drinkers.  

Bottom line: Brewing great beer is hard. Sourcing unique yeast and bacteria should be easy.

We're super pumped that you've come to check us out, and we can't wait to be a part of your brewing process. Welcome to The Yeast Bay!


From 8/21 through 9/21, if you purchase 3 or more vials (either in one order or cumulatively across a number of orders), you'll be entered to win two free 3-gallon Better Bottles! We'll select the winner on 9/22 and send them out shortly after.


While the warmer months of the summer are winding down, it's still rather hot all across the United States. If your area is experiencing hot weather, please remember to use the tracking information provided to have the package held for pickup at your local USPS branch. 

Even brief periods of time on a delivery truck can significantly warm the product. Having the package held at your local USPS branch will ensure the package will not be placed on a hot delivery truck and will instead be held inside the USPS branch protected from excessive heat.


Wanna know what we're up to at The Yeast Bay? Just dying to know what incredible strains we'll be isolating just for you, and when products will be available? Keep up with us by subscribing, and you'll be the first.
