Description
A non-GMO thiol-releasing strain: it cleaves bound precursors out of malt and hops during fermentation, so the beer gains free citrus, pomelo and pineapple aroma that no hop addition alone would deliver. Because it is not engineered, that release comes with far less sulfur than bacterial-gene strains. Ferment warm and let it free-rise to about 30C; attenuation is modest, so keep worts above roughly 18 Plato highly fermentable.
