Bootleg Biology Solera Sour Blend Yeast (Packaged: 6 dec 2019)

A “living” culture blend propagated from our carefully managed continuous solera fermentation.

Many lab-produced multi-species culture blends fail to reproduce the richness and complexity of traditional lambic-style fermentations in their first effort. This can be a result of artificially slamming together cultures after pulling them directly from the freezer.

Instead, our Sour Solera™ Blend contains a unique and complex collection of Saccharomyces, Brettanomyces, Lactobacillus, Pediococcus and other funky yeast and souring bacteria pulled from an active fermentation. This blend can sour in a matter of months at 70ºF or higher, or if you prefer a more prolonged fermentation, use large amounts of aged hops and/or ferment and hold at temperatures below 70ºF.

This blend is available seasonally, and will always be changing and evolving due to the nature of solera fermentations. Warning: No two Sour Solera™ Blend releases will be the same, and neither will their fermentations.
