I have a home brew contest tomorrow. I have 3 kegged brews that I will serve to the public, but the official judges require that we submit our brews in bottles. I tried the other day to transfer my pale ale to one of my flip top bottles. I placed it in the fridge for 30 minutes and when I opened it, it was flat. I must be missing something. I've had brewpubs put beer in growlers to go and they stayed carbonated for a few days. What am I doing wrong? Any suggestions? Is there an easy way to purge air in the bottle with my CO2? I'd really appreciate your help. I'd hate for these great brews to lose points for something stupid like carbonation issues.
