We have traced the source of the under carbonated bottles of Pure Hoppiness to the power failure we experienced on July 31st. We tried our best to recover by alternate means after our carbonating stone got plugged up. We thought we had slightly low carbonation at the worst but it appears some people feel otherwise. We will be trying to re-distribute bottles back to all the retail stores so they can handle exchanges. Pure Hoppiness bottles purchased in the brewery can be exchanged. They will be the new, Belgian style 22oz. bottles. New bottles will be available at the brewery on Tuesday, August 21st, elsewhere some time after that. Sorry for any inconvenience.
