I just brewed my first batch on Sunday: Midwest Supplies' Raspberry Wheat extract kit with White Labs WLP300 yeast. While the brew process itself went well enough—at least, as far as I can tell being a first-timer—the coolest place I could find in my apartment still hovers around 70–72 degrees, which is a bit warmer than these yeast like, as I understand it. I'm using a 6.5-gallon plastic bucket as a fermenter with a 3-piece airlock.
Now, just three days after brewing, the airlock is bubbling only 2-4 times a second. Is this a sign of a stuck/sticking fermentation? Should I re-pitch?
