Yeast Thumb 27

Belgian Saison I

Well-regarded as a farmhouse ale strain despite fickle fermentation behavior. It has fruity complexity, noticeable phenolics and a tart, dry finish. Though it behaves better at warm fermentation temperatures, it is still well-known to stall around 1.030 OG. Try using an additional strain to aid attenuation. Or use Saisonstein® (OYL-500), Belgian Saison II (OYL-042) or French Saison (OYL-026).

This strain tests positive for the STA1 gene, an indicator of Saccharomyces cerevsiae var. diastaticus. This strain may have the ability to metabolize dextrins over time, resulting in higher than expected attenuation.
