Omega Yeast produces fresh, high quality and pitch-ready liquid yeast for Probrewers and Homebrewers. We’re a dedicated crew located in Chicago and St. Louis — a handful of microbiologists, homebrewers, professional brew staff and craft beer fans who have made it our express purpose to make brewing easier and better for everyone.

Be Fresh

We believe the best yeast is the freshest yeast. That’s why our Probrew pitches are always custom made-to-order, and delivered the date you need them. And Homebrewers can find a selection of our vigorously healthy yeast at a local homebrew shop near you.

Be Curious

We believe in experimentation, innovation and questioning the status quo, which is why we produce over 75 strains, including common workhorse varieties and several unique ones that you can’t find anywhere else. Our proprietary propagation method generates metabolically strong yeast cells, with consistent fermentation and optimized cell counts.

Be Helpful

As much as we love our yeast, we’re just as proud of our people and service. We promise to make it easy for you to focus on brewing because we’re always here for you. Check out our resources or email us any questions — we’re here to help.

We hope to work with you!

Testimonial el castor

The Omega lacto blend (OYL-605) worked exactly as advertised, and sourced 20 bbl’s of un-hopped wort overnight to a pH of 3.4. We’re very happy with the results, and will be using it again.

Testimonial devil

Excellent customer service, yeast strains, viability and health of product. Omega helps me make the best beer possible, and I look forward to using them in the years to come as my brewery grows. Via Kviek!

Testimonial singlespeed

Not only is Omega at the forefront of innovation in yeast, but Lance, Mark, and team are extremely dedicated to providing customer service of the utmost quality. There seems to be a strong relationship between trends in craft beer and new products coming from Omega, be it with the use of their Saccharomyces, Brettanomyces, or Lactobacillus strains.
