Okay, I checked the "champagne-style" bottles at the liquor store tonight while I was there. DFH Theobroma had the same size cap as a 22-oz. bottle of Rogue Dead Guy. The belgian beer (that I can't remember the name of) next to it with the same kind of "champagne-style" bottle had a visibly larger cap on it. So there are two kinds of bottles, even though they look the same shape, that take different caps.
