Thiol Libre - How to Use

Thiol Libre liberates tropical thiol aromas in your hops and malt.

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 fast. It can be repitched for 8 generations with consistent results.

Our tips for liberating thiols in your beer:

1. Select a yeast such as Thiol Libre that has strong IRC7 activity.
2. Select hops with high amounts of bound thiols, such as Cascade, Saaz, Calypso, and Perle. This opens up the possibility of using and enhancing locally-grown hops! Use these in the mash (mash hopping) and whirlpool. You can dry hop with the big-money hops like Citra and Mosaic later on if you like!
3. Try adjuncts like Phantasm that contain a high amount of bound thiol precursors.
4. Experiment with base malts, including locally-produced options. Different malts have different bound thiol concentrations.
