I made a california common the other day using white labs 810 yeast which says it directly pitchable, its been almost 48 hours and no signs of fermentation, neither bubbling and the gravity reading is the same as it was prior to pitching the yeast. I poured back and forth and shook the fermenter prior to inserting the airlock, and shock for 7 mintues today just in case but still got nothing. Temp is between 68-72 F.
I did not do a starter, which my be my whole problem. i ordered some more yeast today.
Basically, any tips, suggestions, etc. This happens to be my very first batch so i was kinda expecting this.
