Notes

Lactobacillus Brevis pitched with yeast. One packet of yeast adequate for the 3-gallon recipe. This is a Kottbusser. Will ferment at 68 degrees, allowing the yeast to rise in temperature after 48 hours. Use Lacto Delbrueckii for next brew, kettle sour to pH 3.8. Modified from reference to move to a more "table strength" brew.
