I've got a braggot fermenting in secondary right now, yeast is WLP001. Reasonably high gravity (original SG was ~1.090). Activity had stopped on my airlock a week ago, so I got ready to bottle it. Gravity at that point was a hair over 1.020. I figured that was probably a little high, so I stirred the yeast up a bit and gave it another couple of days. No SG change, so I pitched some Champagne yeast, thinking maybe I'd killed the yeast with alcohol levels. A short time later I had some healthy activity. That was 5 days ago. It's still bubbling every 15 seconds or so, but I just checked the SG and it's still ~1.020. It tastes pretty good and much drier than I would expect for the gravity reading I'm getting. Anyone have any theories as to what might be going on here? I'm a bit confused.
