This is my first attempt and I'm brewing 2 gallons of a Bourbon Barrel Porter. Being a first timer, I'm following the directions as close as possible. The difference is that I used a yeast starter which I prepared 2 days earlier. After transferring the wort to the fermenter and adding my yeast, I added the airlock and placed the carboy in an area of the house that is a consistent 65 degree a in the box it came in to shield it from the light. There was quite a bit of bubbling in the airlock within 24 hours.
The instructions say that fermentation should last 2 weeks when the bubbling should stop and the Foam Cap drops to the bottom of the fermenter. Bubbling seems to have stopped but the Foam Cap is still floating, It's been 2.5 weeks from brew day. Does the foam cap ever stay on top? Should I wait longer? Any suggestions would be seriously appreciated.
