I have been corking a few Belgian beer bottles with every blond, saison, and strong dark I have made for the past 5 years. I tried to open a blond ale that I aged from 2010, and the cork cracked, and I had to use a cork screw to get the cork out. I also tried to open a 2011 blond ale, and none of the guys in the club could get the cork out of the bottle either. I again had to use the cork screw. Both beers had plenty of carbonation and should have helped push the cork out. This has happened with several bottles.
Has anyone had similar problems and found a solution? I have purchased some larger bottle caps that fit champagne style bottles, but the cork effect is really cool at club meetings and beer gatherings.
