I have 5 gallons of beer, if I keg then use a beer gun to bottle some of it do I have to keep all those bottles in the fridge? Will the warm up ruin the beer or carbonation?
It's better to store beer cold than warm, but if you were good with your sanitation and bottling it would like buying refrigerated, commercial beer off a shelf. It isn't going to be immediately ruined, but it will age faster.
