It's not my choice either. I just solicited people for bottles, and surprisingly was given quite a few screw-tops from different sources (same brand of champagne, too, actually), along with "normal" bottles. This brand must be the "Bud Light" of champagnes or the go-to bulk purchase of establishments. in this area,
The ID of the opening looks consistent with the normal bottles, so i would imagine the corks, themselves, will work. I was just concerned that threads would interfere with the operation of the corker or the effectiveness/integrity of the cages. I do plan on taking one into the LHBS to kick the tires; see if it's a legit option. I DO have access to the plastic, reusable corks (which I've used in the past), but don't care for them too much and would like some better aesthetics.
Thanks!
