How long is everyone taking to get the ph in the 3.5 range and at what temps? I was planning to use yogurt at about 160

Omega's blend got me there in 18 hrs at 75F. I dropped it to 4.5 with lactic acid before the lacto starter was pitched.

Try lowering the pH to 4.5 before pitching. The idea is to preserve head retention because the lacto won't degrade some of the head forming proteins at that pH (rudimentary explanation) It seems to have worked for me. This pic was taken about 5 min after the pour.
