Dogfish Head's Chateau Jiahu: Mmm... It's based on a 9000 year old recipe very loosely. It's a sweet and bubbly brew with a nice little punch to it. Reviews suggested that it's pretty close to what mead would have tasted like if mead had honey in it. Something like that anyway.
Just tried it a couple of months ago, totally in love with it when I'm looking for a beer to sip on.
