So I plan on making a rather sparkling beer for my wedding in May, and I'm wanting to go for somewhere around 4.5 - 5 volumes of CO2. Regular old brown bottles will surely explode at this pressure, and I don't really have the money for a corker, big bottles, cork, and cages. So what are my options? Anyone know any sources for thick, heavy bottles of a decent size that can just be capped? As much as I'd love to go out and buy ~50 bottles of a good belgian of the same carbonation level I'm going for, I'm simply not a millionaire.
