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!


Lance Shaner + Mark Schwarz


"Omega has become a force in yeast supply for the craft brewing industry. Their offering reflects the needs of brewers in these dynamic and creative times. Also, when it comes to customer service, Lance and his team feel more like a partner than merely a yeast supplier."

Phil Wymore, Perennial Artisan Ales, St. Louis, MO

"Omega is a fantastic yeast company and has become the sole provider for our brewery. With a wide range of top quality yeast, price, quick shipping and the best costumer support we have received from any other company, we believe Omega is a vital part to our growth."

Tommy Miller, Noble Rey Brewing Co., Dallas, TX

“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.”

Daniel, Le Castor Brewing Co., Rigaud, QC, Canada

"Lance and crew at Omega are great, new place looks fantastic and the yeast is quality. Keep up the good work guys."

Cam Horn, Elmhurst Brewing Co., Chicago, IL

"We really love working with Omega. Every order is delivered on time, the yeast is always fresh and reliable, plus their staff is super knowledgeable and always willing to help.”
