Description
A Saccharomyces cerevisiae engineered to produce lactic acid during a normal primary fermentation, tuned to land around pH 3.5. It is a single pitch in a clean fermenter — no kettle sour, no Lactobacillus, no separate souring vessel — so it is typed as an ale rather than a wild culture. Fruit added afterwards will drive the acidity further.
