With Thiol Libre, you get more intense tropical fruit aromas in your beers without adding more hops or adjuncts. Thiol-liberated beers display strong guava and passionfruit notes even with old-school hops like Cascade. This strain also ferments faster than other high biotransformation strains and produces stable haze. It can be repitched for 8 generations with consistent results.
Optimum Ferm Temp: 17–23ºC (63–73ºF)
Alcohol Tolerance: Medium
Biotransfermation: Very High
Phenolic: No below 23ºC, subtle above 23ºC
Escarpment Labs was started in 2013 by three fine fellows in Ontario. Richard Preiss started isolating the yeast strains he used in his homebrewing. This piqued the interest of his labmate Angus Ross - also a homebrewer and beer geek. Soon enough, they were both isolating yeasts from bottles of beer as well as the Ontario wilderness, resulting in a large and diverse strain collection. We now have an expansive collection of both innovative and in-demand yeasts - some available now, with many more in the development pipeline. Nate Ferguson, an instructor at the Niagara College Brewmaster Program, has since joined the team, his technical expertise in all things beer and yeast helping us to produce high-quality cultures on an industrial scale.
