I am making a barley wine with an approx. 1.108 OG. I have 2 yeast starters going that I made last night. I'm waiting for my girlfriend to finish cooking dinner so that I can have the kitchen to brew. However, when I was waiting, I started playing with my new blow off tube. I tried to put it in the hole where the air lock goes and it fits, except it doesn't seem that it's air-tight to me. It slides in way too easily. So my question: will using an air lock for this beer cause my 6.5 gallon bucket to explode?
