I’ll explain my setup before I get to the question. I have a 1 gallon jug inside of a cooler for fermentation (I live in FL and its HOT). I’ve been using ice and frozen bottles to get the temp in the correct range. The airlock doesnt fit with the cooler top closed, so I’m using blowoff tubing that goes from the top of the jug to a glass of sanitized water.
I started fermenting Caribou Slobber a day and a half ago. The cooler temp started out around 75, but I got it down to 70 fairly quickly. There was a pretty rigorous fermentation in the first day and my blowoff tubing came out of the glass of water for around 12 hours. I’ve read that as long as active fermentation is taking place, its not a big deal. I now have the tube attached to the glass in a way that it wont come out anymore. I’m assuming that the high temp in the cooler lead to a very quick fermentation or my blowoff tubing coming out of the water had some kind of effect? Now two days into fermentation, there are little to no bubbles coming out of the blowoff tube.
Last night before bed I added a jug of ice to the cooler. When I got up this morning the cooler temp was 60. So it went from 70 down to 60 overnight. Did I shock the yeast into working extremely slow?
P.S. - I’m working on temp control haha
