Omega Yeast Saisonstein® OYL-500 is an Omega-original, genetic hybrid of two Saison strains, the French (OYL-026) and Belgian (OYL-027). OYL-500 is versatile, aromatic and attenuative with a silky mouthfeel, exceling in high gravity and ferments more than its parents. From the Belgian side it gets its spicy, complex, tart, dry and crisp with some bubblegum character. As well as fruit characters and fewer phenolics than its French parent. Attenuation is 80-90% or more.
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.
Omega Yeast's metabolically healthy cells produce vigorous fermentation and consistent results for home brewers and probrewers alike. Each homebrew pack (150ml) is packed with 225b cells.
