When the 60 minute mash rests were complete, I removed the grains and boiled each wort for 5 minutes before chilling them to 95☏/35☌ before taking measurements showing both worts were at the same 1.040 pre-boil OG and 4.5 pH. With the waters properly heated, I incorporated the grains then set both controllers to maintain my desired mash temperature of 150☏/66☌. I then weighed out and milled the grains. As such, I started this brew day by collecting identical volumes of RO water in two identical kettles, adjusting them to the same mineral profile, then flipping the switches on my Clawhammer Supply 120v controllers to get them heating up.

A more unique approach involves inoculating wort with probiotics such as Goodbelly, a typically fruit-flavored liquid drink that contains ample amounts of L. Brevis, which is said to produce a clean acidity in as little as 1 to 4 days. With the rising popularity of quick sour methods, many yeast labs have begun to produce pure lactobacillus cultures such as Imperial Yeast W25 Lacto. The most prominent bacteria used to produce sour beer is lactobacillus, of which there are a few species. ![]() While brewers in some regions developed approaches to better control the outcome of their intentionally sour beers, the time it takes for certain souring bacteria to work was a barrier to many, though more recently, some methods have been developed to hasten the turnaround time of these unique styles.
