Rauch Bock

Now for a beer style I've been longing one year to make. As you may already know, I love a deep smoke flavor in certain beers. Originally this was going to be a pale smoked lager with almost 50% rauchmalt. Then I massaged the recipe several times, and it became much bigger, and much darker. I had a good recipe going, and it was dipping into the bock category. While re-assuring myself with some recipes in Smoked Beers, I noticed it wasn't far from one listed in the book. So for this one, I've decided to simplify, and stay close to their recipe.

The all-grain mash will be a stepped infusion, with a protein rest to break up some proteins in the dark wheat. This rest, and the CaraFoam addition should provide the beer with a striking dense foam head. The saccharification rest will be held at 153°F. Unfortunately, we used the sacch-water (1.825 gal) at the beginning for the first protein rest infusion, and ended up with a thick dough-like ball. So we added hot liquor to finally end up with a thinner consistency at the high end of the protein rest range. In the end, we attained adequate temps for both rests. As you can see, in the picture we're raising our glasses (last bottle of 1 year Munich Dunkel) to celebrate the mash's end, and progression to a full wort boil. Thank you Matt for all your help.

With just one a ounce, 90min addition, the hop bitterness in the Smoked Scottish Ale 2 is just about perfect. It balanced the malts and higher FG, but it doesn't linger anywhere in the aftertaste. So for this smoky bock, I'll stick with a similar IBU level, and just give it a kiss of hop flavor in the finish. Vanguard is a US cross breed similar to Hallertau Mittlefruh.

Nice! I am a huge fan of the of the bocks and this sounds great. Its awesome that you went authentic on all German malts. Good stuff!

Wow. You guys look so calm in that picture. It was right about that time on my brew day, that my buddy and I were dealing with 1 gallon of boiling wort shooting out of the top of the kettle all over the back porch. I mean, we were laughing. But not toasting.

German malts are the way to go. I really like how they worked in my Czech Pils, and the color from the dark wheat for this Rauch Bock is simply amazing...deep orange/brown.

The mash could have been a nasty ordeal, but we managed to get through it just fine. The run off became very cloudy at times, and we had to sparge quite slow.

In that picture, we were waiting for the boil to get going, and Jimmy John subs arrived. See...we were very happy.

Later we did have a very small boil-up, but didn't loose anything, and got all the hop residue from the lid back into the wort. Boil-overs are awful. Yuck!

Did you just do another infusion after the protein rest, or did you do a decoction to get it up to the sacch temp?

Ted Danyluk said...

Kevin Lavoy,

I stuck with my step infusion plan. I suppose a decoction would have worked very well for this. Especially if we added the initial strike volume at a medium ratio of about 1-1.35 qt/lb. We ended up low on our Sacch rest (wanted 154*F), but I figured it would be fine. I think I'll do the decoction mash next time...or I should, say next year.

I'm planning a Quinoa Lager soon, but don't want to decoct the mash.
