Daily check in on my stout, seems to have gotten a bit excited in the night.
E1: Changed out the airlock, sanitized, the whole shebang. Came back 5 minutes later, it happened again lmao. Swapped in another clean airlock, this time with some vodka in it to see if that helps.
E2: Swapped out the airlock again, this time with more vodka, hope that helps keep the bubbles down. This is so exciting!
E3: I've been checking back every hour or so, it's blown over again at least once. I guess I should be happy that my beer is fermenting so actively lol. Looks like I'm gonna be swapping out the airlock every few hours today, until main ferment dies down.
I think the risk is low as long as you are doing a relatively quick ferment. I wouldn't let it sit in secondary for months or anything.
