I am going to keg my homebrew for the first time and take it to a friend's wedding. I have the CO2 system set up and I have checked it for leaks and practiced with H20. Everything is set to go. I need some help about what do next however, because I have to transport the beer twice and I don't have a fridge to keep the beer in (my plan is a cooler and ice). Here's the scenario: Beer is ready to be kegged, the wedding at which it will be served is in 14 days. The beer is in a carboy two hours away from my home and I will need to transport it to my home this week before the wedding. Then, two days before the wedding I will need to transport it from my home 5 hours away to the wedding. What would you do? [more inside]
