This weekend, I'm getting ready to brew the biggest beer I've ever brewed. It's called opus 10. It's an imperial chocolate coffee stout. O.G. Is projected to be in the 1.095 range. I'm doing a yeast starter, and I'm worried about an explosion in my closet as it ferments. I use the 6 gallon buckets and the opening on the lid is, in my opinion, too small for a blowoff tube of any substantial size. Does the O.G. of a beer have any relation to the amount of Kraeusen?
