Brew #56: Doppelbock

I kegged the German Pilsener today, and since I had a fresh and healthy yeast cake in the fermenter this was a perfect opportunity for brewing a strong doppelbock for the spring. The recipe should hopefully result in a rich and malty bock. I mashed quite high, so there should be lots of complex non-fermentable sugars. Interestingly the mash efficiency seems to have increased. I'll leave this in the fermenter for about three weeks.

The batch was brewed 2007-12-20.

Very nice! I just had a few glasses of the doppelbock I brewed this summer the other night...what a great style.

Did you decoc? I did a double on mine, it's not actually as bad as people make it sound. It also gives a very nice roasty flavor. How long are you going to lager this?

Gotta use that yeast! Cheers!

Yeah, doppelbocks are really nice. I used a single step infusion, so no decoction. I'm not entirely convinced that they're actually worth it. Instead I used quite a bit of specialty malts.

I'll lager it until it runs out. ;)

At a minimum it'll need at least a month of cold lagering.
