Default Ok buddies, 5 gal. blowoff or 6.5 for primary?

Do you guys usually let the krausen fall into the wort or do you let it blow off? The book said it has lots 'o stuff in it... do you differ with the style of brew?

I suppose it really depends on the situation. If it is comming out of the airlock, I'll use a blow off tube, otherwise, I let it be. More than 99% of brews, don't need the blow off tube.

Letting the kraeusen fall back into the beer don't affect it as long as the kraeusen don't get aerated itself. Under airlock, this seems hard to do.

I leave it and haven't noticed any off tastes in my brews.

I use 6.5G carboys...blowoffs are a PITA and you loose (not much but enough to make me cry) beer. I like to keep it easy.

I use a 6.5 gallon carboy for my primary and I always attach a blow off tube just in case. I've never had to use it, but better safe than sorry.

I did come mighty close to making use of it last Tuesday with my Hefeweizen though! Man those Hefs are a violent beer! The yeast has that lovely scent of .

There is a good article in Septembers BYO that explains how to make a "Burton Union" It's the homebrewers version of an "English fermentation system" Its one step up from a blow-off tube and lets you harvest yeast
during your fermentation. A parts list is included in the article.

It's an extract recipe. Are you looking for AG or extract?

The only time I even got close to needing a blowoff tube was with a barleywine, which had an OG of 1.123...so those nottinghams had a lot to chew on.

Orpheus, I'll second that one... Been fermenting a wheat doppelbock for the past week, and my aging/fermentation room has smelled like ripe bananas...yum! What yeast did you use on your hefe? I'm using the Wyeast 3333, German Wheat. Cheers to those bastards, who have done a hell of a job! I cannot wait to taste it.

Hey, pirate ale, if you're willing to do partial mash, here's my wheat doppelbock recipe from last weekend...
