my friend and i brewed a batch and had the beer in 1 liter bottles and bottled them 2 weeks ago. well he said he cracked one open and it was ready to go. i was hesitant cause it was only 2 weeks. i put my share, 4 1 liter bottles, in the fridge trusting him on his word. well i opened 1 up and it had some head to it, but tasted flat. my question is, if i pull them out of the fridge, will they continue to carbonate? or did i kill the process by having them in there over night?
