Made a Lacto Plantarum starter on 5/31/17. 200g DME in 2 liters water, boiled for 5 minutes. 10 pills broken open and pitched into the starter after the wort cooled down to 92ºF. Each pill had 10B cells for a total off 100B in the starter. Starter topped off with seltzer water to purge oxygen in the head space. Initial pH was 5.39. Final pH of starter was 4.51.
Initial pH of the wort after pitching the starter was 4.51. We pitched at 12:30 pm and held at 95ºF. By 9 pm, the wort was down to pH 3.73. At 9 am, the wort was down to 3.51. By 12:30 pm (24 post pitch), the wort was down to 3.43. Due to time restrictions, I decided to call it there and finish the boil.
