Different PH for different yeast observation
« on: October 22, 2013, 06:42:14 PM »
So i brewed a 8.5gal batch and split it into 5.5 Gal and 3 Gal. Pitched 5.5 with 2 packs of dehydrated 34/70 and 3 gal batch with a proper starter of Wyeast 2206. They both finished at 1.016. Interesting thing is that 34/70  PH dropped from 5.63 (post boil PH) to 4.58 and 2206 PH dropped from 5.63 (post boil PH) to 4.7.
They are both a little high in my mind but it is what it is i suppose.  PH and brewing continue to elude me sometimes i wish i never even purchased that damn PH meter:)
