Fermentation, Evolved.

Founded on the belief that fermentation could go further. We're here to help brewers take risks, refine flavor, and move the culture forward.

Omega Yeast is Born

Founded in the back of a costume shop with one conviction: Chicago brewers deserved fresher, more reliable yeast. So we started making it.

Be Fresh. Be Curious. Be Helpful.

Custom-propped to order. Delivered direct. Brewers stopped worrying about viability and started pushing recipes further. That momentum earned a second facility, a growing team, and a new identity to match the ambition.

Doubling down on the future

Doubled R&D capacity. New equipment, new capabilities, new questions to answer. This is where the next generation of yeast science took shape.

Engineering the Future

Thiolized. DKO. Lumina. Zing. Years of R&D led to a suite of technologies and engineered strains designed to give brewers tools that didn't exist before.

What's next?

New strains, new technology, and new initiatives. Incoming...

  • We time every prop backward from your brew day. That means shorter lag times, vigorous fermentation, and yeast that's performing the moment it hits your wort - not recovering from weeks on a shelf.

  • Creating and evolving strains for specific flavor profiles and performance goals.


  • Fast, rigorous testing of every batch to ensure it meets our exacting standards.

  • We work side by side with brewers to troubleshoot, refine and innovate.
