Ok, there's all this talk about 12/21/12 and how the gravity is going to reverse or a meteor is going to incinerate us or an alien race is going to steal the world's supply of beer. The latter being the worst of course. So in honor of all of this negativity, I decided to make something! Something extreme, something that deserves the name Doomsday. After reading about many unique styles, I settled on an Eisbock. Sounds extreme, partially freeze your beer after fermentation! To up the extremeness, I think I will also add a touch of a different non fermentable to each bottle so you will not know exactly what you will be getting from each bottle. This sounds like a good doomsday beer. I have never brewed an Eisbock, so I am looking for some advice / critiques from those who have. Take a look at the recipe I have concocted below. Any suggestions on the recipe, how much to freeze, temps to use, aging, non-fermentables to use for bottling, etc would be awesome! The final bottling volume / ABV / IBU may be different than what's listed here since I will partially freeze and only extract the concentrated beer:

Digging up and oldy! Unfortunately, you did not find gold. I didn't brew this one. I didn't know enough about the style to feel confident in getting a good representation. Hopefully for the next prophesied doomsday date, I'll be ready to go! If I do it, I'll re-post on here. Thanks for checking out the thread!
