Species: Saccharomyces cerevisiae var. diastaticus

Profile: This strain is the classic farmhouse ale yeast. A traditional yeast that is spicy with complex aromatics, including bubble gum. It is very tart and dry on the palate with a mild fruitiness. Expect a crisp, mildly acidic finish that will benefit from elevated fermentation temperatures. This strain is notorious for a rapid and vigorous start to fermentation, only to stick around 1.035 S.G. Fermentation will finish, given time and warm temperatures. Warm fermentation temperatures, at least 90 °F (32 °C), or the use of a secondary strain can accelerate attenuation. This Wyeast yeast strain has been classified as Saccharomyces cerevisiae var. diastaticus using rapid PCR analysis. This strain carries the STA1 gene, which is the “signature” gene of Saccharomyces cerevisiae var. diastaticus and will be found in all diastaticus strains.
