Sour Cherry Funk

GB150


Description Blend of 3 Brett strains and Lactic Acid Bacteria This blend creates an amazing complex, sour beer with fruity cherry esters. Fermenting in the presence of 7-10 IBUs will cause the fermentation to complete much more quickly but will slow the souring — expect to wait 3-4 months for significant souring. Fermenting with zero or less than 5 IBUs will allow souring to happen much faster (within two weeks) but will cause the fermentation to take up to 4 weeks to complete.

* Attenuation was measured after 8 days with Ale yeast at 70˚F and Lager yeast at 50˚F. Medium Gravity is 14˚ – 16˚Plato. High Gravity is 23˚- 25˚Plato.

† The working temperature range represents the range at which fermentation for a given strain produces a typical attenuation- not necessarily the ideal temperature for your particular beer style. As a rule of thumb, start ale yeast fermentation at 68˚ – 72˚F and then lower or raise temp as desired. Lager Yeast are typically fermented at 45˚ – 58˚F. If desired, Lager Yeast can be given a “hot start” at 65-68˚F and then lowered to the primary temperature after active fermentation begins (10-20hrs).
