So my yeast started out relatively slow here, but 36 hours in I've never seen so much activity. Had to remove the airlock and run a blowoff this morning and got a dose of foam to the face when I took it out; glad I did it because I would have come home to a mess if I hadn't checked before leaving. I knew that I didn't leave enough headspace when I capped my fermenter, but didn't want to mess with the volume as the OG came out just where I wanted it on the first try.
So to get the point.
If after two weeks in primary the activity has died down substantially but the gravity is still too high, what are the steps to reactivate fermentation? I did my best to oxygenate the solution before pitching, but I obviously don't want to bottle this stuff if I only get it down to 1.020 or so. Can I just pitch more WLP500? Seems like it might not take off if there's not much oxygen in the wort, but seems like trying to aerate it so far into fermentation would be risky.
Any suggestions?
