I have been reclaiming yeast from my primary fermentations; one in particular (wyeast greenbelt) has been building pressure while stored in the fridge in its mason jar. I just crack it open and release the pressure. Am I harvesting too early? I know, what's the gravity reading right? I admit I don't check gravity before I move to secondary I just wait for airlock to slow to one bubble per minute or so. Does anyone else have this or should I leave a little head space for the pressure?
