The following is a statement by Lance Shaner, owner of Omega Yeast Labs

Lance Shaner Full disclosure: I own Omega Yeast Labs. Pitching at 120F is a bad idea with this blend. The bug doing most of the work in this blend is Lactobacillus plantarum. The best temp for plantarum is 80-90F. It does not work over 100F. Also, we regularly make a 1 liter starter with the Lacto blend for faster souring. Simply pitch the contents of the pouch into 1 liter of sterile 1.040 wort and let sit for 24 hours at 70-80F before pitching (no need to stir). Adi Hastings mentioned the imperial stout we just kettle soured. We previously brewed a Berliner using the same method. At 17 hours, pH was at 3.42 and temp was 75F (original pitch temp was 85F). At 40 hours, pH was 3.24, at which time we boiled. Lower pH in the Berliner compared to the stout at 17 hours likely has to do with different buffering capacities in different worts.
