Quick Info

  • This true genetic hybrid is a beast at devouring sugars, which creates a very dry beer without any of the peppery, clove phenolics associated with saisons and Belgian ales.
  • Expect a citrus-forward aroma with hints of peach and a clean finish.
  • Gulo Ale excels in any style where a high level of attenuation is desired without phenolics.
  • We love using it in an IPA (including a brut IPA), stout, or Bière de Garde. Non-phenolic. 

Product Overview

Gulo Ale is the latest creation to emerge from the curious minds of our R&D team. The progeny of Irish Ale (OYL-005) and French Saison (OYL-026), this true genetic hybrid is a beast at devouring sugars, which creates a very dry beer without any of the peppery, clove phenolics associated with saisons and Belgian ales. Expect a citrus-forward aroma with hints of peach and a clean finish. Gulo Ale excels in any style where a high level of attenuation is desired without phenolics. We love using it in an IPA (including a brut IPA), stout, or Bière de Garde. Non-phenolic. Patent Pending. 

This strain tests positive for the STA1 gene, an indicator of Saccharomyces cerevisiae var. diastaticus, and is capable of fermenting dextrins, resulting in very high attenuation. 

The hybrids in this strain catalog were invented by Omega Yeast as the result of years of research and development. They are yeast strains that have never before existed. Although patenting brewing yeast strains is a somewhat novel concept, we made the decision to file a patent application for the unique Gulo® Ale strain to protect the time, creativity and expense invested in developing it. We recognize the brewing community's conventions of propagating in-house, repitching, and sharing cultures with other like-minded brewers, and while we want to protect our investment in Gulo®, we have no intention of stopping breweries or individuals that have purchased a culture from us from using it as they would any other non-patented strain. So, carry on brewing, and we will carry on creating quality Omega Yeast strains.
