Both. I was in Richmond, VA last weekend and there is fantastic bar there called Mekong. I highly recommend it if you ever find yourself in Richmond. They have an amazing beer selection and they had the beer on tap. Never seen that before. I have seen it in stores here in NYC too, albeit not everywhere.
I do know that Jungle Jim's in Fairfield had it last year. I'm not sure about this year, but I'm sure you could call and ask or tweet to them (they are good with Twitter).
Again, and I don't want to overhype it, but it really was the best Christmas/Holiday Ale I've had.
