I bottled a batch last night and about 16 of my bottles were dos Equis or modelo bottles. I use a hand capper from brewers best. This capper will not cap those bottles. If I wouldn't have still had my cheap capper from mr beer I would have been in trouble. My wife was helping me cap while I was filling bottles and after a considerable amount of profanity she walked off. I gave it a try and after about the same amount of profanity I realized the problem. No more of those bottles for me.
