Here's what I have done:
I bought 5 gallons of unpasturized, no preservative cider from the cider mill.
Took it home & poured it all into my fermenting bucket & added 5 crushed campden tablets, 4 tsp yeast nutrient, 2 1/2 tsp pectic enzyme and put the lid/airlock on and let it sit in the basement @ 61*F.
After 24 hrs I sprinkled 1 packet of Safale S-04 dry yeast to the surface & reinstalled the lid/airlock.
Day 5 with no airlock activity, I moved the bucket upstairs where the temp is 63*-68*F
It has been 6 days now & I have not seen any airlock activity. I took a hyrometer reading & it is still @ 1.050 (same as it started at last sunday)
Any of the cider that I have done previously has started showing airlock activity within 3 days of pitching the yeast. Any suggestions?
