This says the guy who puts up with the non-standard Corona bottles (not all are, some Corona bottles have the bulge in the right place to cap properly) but I do like to have one or more clear glass bottles per batch so I can see how the beer is clearing (or not clearing).The real answer to the problem is to just discard the bottles that don't crimp right. Bottles are not expensive to buy and often can be had for free. Life is too short to let non-standard bottles ruin your beer.
