Cut the top off, stick a piece of rebar in there, and take your giant beersicle to a party.
I put it back in the fridge after defrosting, let it settle for 2 days and poured my first last night after a long business trip to Atlanta. Not sure if it was the long day but it tasted pretty darn good! Crystal clear too! Go figure....in fact, I think I'll try it again now!
