It's basically just a metal table you can fit a keg and ice bucket under. It's got holes in the top, so you can feed the tap through and clip it to a branch.
The top is about three feet off the ground, and the tree sits on it. So it's not like a normal stand. But they say it can hold trees up to five feet tall and 150 pounds.
Each one will cost $50 at TreeKegStand.com. They go on sale at 10:00 a.m. Eastern next Thursday. If you want one, set a reminder and hope you get lucky. It sounds like there's a very limited supply.
They're also selling "Beernaments" again this year . . . oversized ornaments you can slip a beer can into and drink out of. Their website says to check back at 10:00 a.m. Eastern next Tuesday for those. (Here's a photo.) (Food & Wine)
