I I have a porter in a plastic fermenter. On top of the cap I have the pressure release thing on top. The water in the piece is bubbling. Does that mean my fermentation is active?
yes, it means there are gases releasing from your fermenter. That's good sign. Just note for the future, lack of bubbles is not a tell tale sign that you're not fermenting.
Grab a comfy chair, pour a beer and start reading. Welcome to the hobby.
All signs point to yes.
I was just wondering because I pitched at about high80 degrees and was hoping I didn't kill the yeast.
