Recipe
This recipe was developed as a collaborative effort by participants in the barrel.
Some participants soured this beer by adding a portion of acidulated malt to the mash after the saccharification rest. Some participants soured by adding food grade lactic acid to the wort prior to boiling. The recipe below follows the second method, but either is OK. Lactic acid was added in 10mL increments, the wort stirred gently, and a sample pulled and the pH measured. Process was repeated until desired pH was attained. In this case that happened to take 50mL of lactic acid to reach a pH of about 3.9. If acidulated malt was used, approximately 2.75lbs would be required. (I believe.)
As described on the Nitty Gritty Details page, the recipe has been scaled to a brewhouse efficiency of 75% and it targets 6 US gallons post-boil to allow for some volume loss during transfers, some hydrometer samples to be pulled, etc… Feel free to scale to your own system as required.
