Description

Dry Lachancea thermotolerans, pitched alone to make lactic acid while it starts the fermentation; once pH reaches 3.0–3.5, a day to four days later, a conventional yeast goes in to finish the beer. CML publish neither attenuation nor flocculation, so both figures here are nominal and describe the souring step rather than a gravity to plan around.
