So I brewed an American Wheat using US-05 dry yeast, primary two weeks and then I transferred it into my 5 gal secondary so I could clean my 6 gal carboy before I added my fruit. I let it sit in the secondary over night and bought Oregon blackberries today. I poured them into my 6 gal ( wanted room for fermentation) and then racked my beer on top. It has been about 8 hours and there is no activity visibly or in my airlock. It's sitting at about 62*F so I'm just wondering if I need to wait longer or pitch more yeast or move to a warmer temp?? Any recommendations would be great thanks!!
