Homebrew RoggenBock

So a while back I tried to do a triple decoction Roggenbock. The decoction did not go well and my brewday ended up being around little over 12 hours. Here is just a short list of issues that I had during that day:

  • First decoction went well, but the next 2 would not come up to temperature. Ended up decocting about 2-3 more times then necessary.
  • The second problem I ran into was testing for conversion. Every test turned up positive for starch. After an extra hour of mash time I just gave up and started the sparge.
  • During the sparge, I got my first stuck sparge even though I used a decent amount rice hulls.

Fortunately, the boil, fermentation, and bottling went by without problems. Now I am breaking one out every so often to try them. First thing you notice cracking it open is the aroma. This beer has a huge banana aroma that dominates with a hint of rye behind it and the color is a rich mahogany. The flavor, like the aroma, is yeast dominated with a hint of rye spice and maltly richness. Carbonation is very light (needs some more time in the bottle), and the mouth feel is very thick, yet finishes smooth and dry.

Once this carbonates up it should a pretty good beer, though I am not sure that I really want to go through the trouble of the decoction mash again. Recipe after the picture.
