View Full Version : Blew the cork off the fermentor!!!
02-21-2011, 04:12 AM
I have never had this happen before and am using a known/easy recipe.
Nut brown ale-- medium extract- hops added at appropriate times during the boil- cleaned and sanitized everything!-
2 stage fermenation planned (Done it before)
30 hrs later- I went down to the basement to babysit the fermentor (temps/conditon/foam line), low and behold the rubber stopper and hose had become dislodged-blown off the the top of the 6 gal carboy.
The 3/8 line from the stopper was clogged with hops and shumtz. (Again never happened before on three diff rounds)
Not a big mess but I quickly cleaned up and replaced with a cleaned and sanitized stopper and new hose.
The wort is literally boiling the fermentor ( temp at 68 deg). I have never experienced this.
Has anyone seen this? Yeah the stopper was in there neck pretty damn tight. Recipe followed to the T.......

Well I've never actually had a blowoff myself, but I understand they are quite common. You could try using FermCap (http://www.brewmasterswarehouse.com/product/0102120/fermcap-s-1-oz), I use it on every batch to keep boil overs and blowoffs from happening.

If you are Dry Hopping add the hops after fermentation has completely stopped. If not you need to strain the hops from your beer before the fermentor. Sounds like you just got stopped up.
Welcome to the forum!

Yeah dude it "boils" in there. I was awestruck the first time I primaried in a carboy.

Its a drag, but no big thing at all. I switched from a 3/8" blow-off tube to a 1" one when I primary in a carboy, just cram the tube into the neck, no stopper needed, never gets blocked...
I was expecting to read that you put a cork in your fermentor. Oh well its still entertaining ;) +1 to the 1" blow off tube.

I second the Fermcap recomendation. Stuff is magical like narwhals and unicorns for keeping fermentation explosions from happening.

Since the explosion, things have settled down. I purchased a ferm cap and will step up secondardy ferementor tonight for transfer. Wish the beer a good trip

I'm just curious..........what yeast did you use?

Yeah it was a three layer cake when I emptied the fermentor out. Shmutz an inch thick. Lots- o -hops

There's a cheap knockoff of nottingham made in Canada that is famous for making a huge yeast cake. To avoid copyright infringement/lawsuits they have cleverly changed the name of the yeast to "That Nottingham" with subscript on the package that reads "It Cakes!"

Say no more, say no more, SAY NO MORE! Notty? say no more..!!

I don't think I've ever had an issue with Notty as far as "violent fermentations". S-04,Winsor and 3787, yes.

Had my first blowoff in 5 yrs of brewing today. Woke up to this:
Good thing it was in the closet or I'd have some painting to do.

I brewed up a Brown Ale yesterday from a True Brew extract kit, added 2 oz unsweetened bakers cocoa at the last 5 minutes and steeped 4 oz sumatran coffee during the cool down. Muntons Ale Yeast added to some extract and water set about an hour during boil and cool down, popped when I opened the jar. placed in the carboy(my 1st time primarying in one) add the vent and start cleaning up. at about 5 hours I thought I saw a bubble in the vent, by hour six it was 2 bubbles a second, 30 minutes later a steady stream of air....this morning there if foam all over the place and the vent is still in. this is only my 5th brew and never had one kick so fast and hard.
I stand corrected. The bottom part of the vent was still in. cleaned up and now bubbling away at about 3 burbs a second.
