I got it right this time, or at least I think so...

Made a Trappist Enkel with a SG of about 1.052.

I did a starter with Wyeast 3522 Belgian Ardennes, 18 hours, then a re-infusion of wort for 3 more hours prior to pitching.

The krausen was about to hit the airlock, so I rushed down to my LHBS, picked up a bung, some tubing, drilled a hole, and made a blow off tube, which is now working perfectly, draining into a bowl of star-san, keeping air out

Is this just a damn good fermentation or will I always have to do this when I nail it?

(Btw, better bottle, 6 gallons, filled to five exactly)

From what I've read, if you have enough room for the krausen, it's not needed. 6-6.5 gallon carboy/bucket for a 5 gallon batch should be OK 99% of the time.

For that low of an OG if you have that much head space it's probably fine with an airlock. Where I usually get a ton of krausen is with the higher gravity batches.

It depends on the yeast strain, pitching rate, ingredients, O.G. etc. Anything with a lot of flaked adjunct or wheat for me really requires a blow off, I had a saison spray the ceiling before.

Yeah that's what I thought too. Pitched at 70 degrees, keeping it in my bedroom which is 64 ambient temperature with wet paper towels over it to cool with evaporation, and it's still blowing off.

I've never used this yeast before, maybe it's this strain?

I'm guessing I took a bad reading for the OG then. With this kind of activity, I'm guessing it was a lot higher.

I have only experienced one messy blow off. Since then, I have always used a blow off tube. So much easier than cleaning kreuzen off the walls, and the carpet, and the backside of the closet door...

Really, though, there's no reason NOT to use a blow off...

99% still leaves that 1% chance. I had my second brew just start showing in the airlock so I quickly rigged a blow off tube and all was good. Now I just start every brew with a blow off tube, then switch to the airlock when thing slow down.

SHMBO is very supportive of my hobby (addiction) but I think that support may just subside if I blew beer all over the walls and ceiling.

I used to use one every time on five gallon carboys. I switched to these rather large carboys 7+ gallone and I can get by with just airlocks. Buts as mentioned, there is really no reason not to. I'd never go back to smaller fermenters though.
