Good evening all, I brewed 10 gallons of a blonde ale 4 days ago (Thursday 4/19) - I created a yeast starter the day before in a 1/2 gallon growler. The starter doubled in size and bubbled over once which let me know the yeast was good to go.
I put 5 gallons of the blonde ale into 2 buckets, one of those buckets had 8 ounces of Pomegranate juice in it (pomegranate blonde) the other bucket did not. I shook the growler well and poured half of it into each bucket at about 75 degrees. 4 days later, the one without the pomegranate hasn't started fermenting yet. I thought it was a bad seal on the airlock/o-ring in the lid but I changed airlocks and taped it so it is definitely sealed.
The non-pomegranate batch was the second pour from the growler (does the yeast float at the top?) or is the other one fermenting only because of the sugar from the pomegranate. Also what should I do? Pitch more yeast in there? The temperature has been steady and if one can ferment in it, I'd assume the other could. Any/all insights are appreciated. Thanks in advance!
