I'm thinking about using one of my 5 gal glass carboys as my primary, so I can enjoy the show of course. Do I need to set up a blow off tube or can I just use an airlock?
I've recently had two batches ferment so rigorous that I blew air locks off the 6.5 gallon primaries...won't do it again and will always use a blow-off tube and 6.5 gallon.
Thanks for the advice all, I got myself a 6.5er and a blow off set up. For the other end of the BO tube, I just put it in a bucket of water? Sanitizer? Cheap Vodka?
I am fermenting a brew ATM in a 7 gallon plastic bucket and if I didn't have a blowoff tube on it, it would have painted the wall and ceiling of my basement with yeast and trub, not to mention cover a lot of my grain supply.
I usually use a 5 Gal carboy for primary, and I usually use a blow off tube into a bucket of leftover sanitizer. I use the 5 gal carboy's because I used to use plastic for primary and carboy for 2ndary - but the buckets got pretty beat up, so I switched to all carboy.
How often do you change the blow-off water if you get a bunch of blow-off material in the water?
