Their backstage series has been Way. Too. Sweet. Lizard of Koz is pretty much undrinkable to me.
This one was when it first came out, but after letting it mellow for a good 6 months or so, it's really nice! Wish I had bought a few more bottles.
Don't think it would be hard to clone, though. Brew a strong golden ale, kill the yeast, back-sweeten with some mango purée, clarify, and then add some habanero tincture to get the heat. Would have to be kegged to maintain the sweetness.
But yeah, after it mellowed it was a great beer!
