I have some apfelwein that is going to be ready to keg next week, and also have a christmas ale that will be kegged in 2 weeks. I am bringing the apfelwein to my gf's christmas party and the ale to my parent's house for the holidays.
Question (these are my first kegging endeavors):
At the gf's, the keg will most likely be left outside the door, I'm in Maine...that is going to mean 30-40 degrees this time of year. I am serving it with a cobra tap off of 3ft of hose. Serving pressure is somewhere around 1psi. I want the apfelwein to be carbonated somewhere around 4 volumes. I will chill the kegs in the basement and put them under the appropriate pressure for about a week. When I get to the party, I blow off the co2, set to serving pressure, and go...how will the keg stay carbonated for the whole night? Or will I have to put it back on the gas? After the party, when I bring home what's left, do I need to put it directly back onto carbing gas, or can I let it sit until i'm ready to drink again? Same questions stand for the christmas ale, which will be slightly less carbed.
Sorry if these are hairbrained questions...I'm just a kegn00b. Thanks for taking the time to read this!
