I know this has been discussed at length in this forum, but I've been unable to find a solution to my problem in existing posts. I'm having trouble getting my wort to ferment. I've done everything as I normally do but I'm getting no yeast activity at all. My fermentation chamber is set at 70 degrees, I oxygenated with pure O2 using an oxygenation wand, and I'm using the same equipment I always use. I've pasted the ingredients below in case that's helpful.
After the first time I pitched the yeast and oxygenated, I watched the end of the blowoff tube for several days and saw no bubbles, so I opened my stainless fermenter and looked inside. No signs of krausen. I waited a couple weeks and pitched another packet of yeast, this time activating the yeast in warm water beforehand. It's been four days and there's still no activity at all.
Both packets of yeast were purchased at the same time and sat in my fridge for several months, but they weren't expired. It's possible (but unlikely) that they were both from a bad batch, though, so I'm thinking of stopping at my LHBS to buy a new packet.
I didn't check the OG before fermentation but the SG right now is 1.0318, which doesn't seem way out of whack. Anything else I should check? Any other thoughts on what the problem could be?
Thanks.
