Backstory: due to my employment situation I've had to move into a smaller place, so my kegerator is in storage. Kind of ironic, since now I have all kinds of free time to brew (and saving money on beer isn't a bad thing either). But I don't have any bottles saved up, and don't really have room for more than a few cases anyway, and buying them at fifty cents a pop means they'll cost more than the beer, at least until I get enough in rotation. Plus I'm spoiled... I can't stand bottling.
So what I'm wondering is if there are any issues associated with keeping a keg warm, and using it to fill a 2 L bottle (with a Carbonator cap) that could then go in the fridge. The furnace is set at 68°F, but I'm thinking the garage (insulated, but not heated) will stay cooler than that, maybe even get down to serving temps once it's colder outside. I guess all I'm really wondering is if there's a dramatic difference in flavor, aging in the 60s versus the 40s.
Anyone have experience with storing a keg warm for a few months?
