WLP320 Dog Whistle

[Oscardevoice]

We're watching a couple of dogs this week, their owners take ours in when we're out of town. Tonight the one dog started freaking out like the world was ending at 4 am. After searching the house I heard the noise in my beer "cellar" (closet) - my first near fermentation explosion. I think I saved it just in time, I couldn't believe how convex the lid was and still hanging on. Anyway.. is this even possible on a medium to low grav brew? Brewing an American Wheat, details of the brew:

5lbs Wheat malt
3lbs 2-Row
3lbs Pilsner

Fermented between 70-71

470ml yeast starter for 18 hours on a stir plate

OG 1.054

Thanks!

Is it possible for it to be fermenting that intensely? Absolutely. I have many different yeast strains do this to me. that just means you have a bunch of really happy yeast. clean her up and as long as you got everything cleaned and back on before the positive pressure was gone, all is well.

Yes this happens all the time. Not sure if you used a German strain, but hef yeasts are notorious for this

My hefes always do this, foam control or not.

This brings back bad memories! Some airlocks have a molded plastic cross on the tip that goes into the fermenter. I drill that cross out to prevent trub, yeast, hops, whatever from clogging what can become a restrictive part of the airlock. If that port gets clogged or restricted, even a subdued fermentation can blow a buckets lid off. Way to go-looks like you saved it just in time.

Thanks gents. I did a clean up and sanitized a new lid and air lock - she looked like this when I made the swap so feeling good some co2 still blowing off.
