Brew #50: Roggenbier

I am quite excited about this beer. A roggenbier is like a dunkelweizen, except that the wheat malt has been fully replaced by rye malt. Not having tried a German roggenbier before I do look very much forward to doing so. It is going to be interesting to compare this batch with a commercial interpretation of the style -- once I get hold of one.

The mash smelled absolutely wonderful when I mashed in. The predominate aromas were rye bread and nutty chocolate. I am not particularly fond of pumpernickel bread, but I do like other kinds of rye bread.

When I started brewing I thought that I had 3 kg of rye malt on had, something I did not, so 750 grams were replaced by wheat malt. This means that the rye content is 40% and not above 50% as dictated by the BJCP style definition. But, who cares. I had absolutely no problem mashing the rye.

German wheat yeasts are supposed to be pitched a little low so that the clove and banana characteristics can develop more, so this time I did not make as starter. Instead I just poured the contents of the swollen smack-pack into the wort. I really wanted to try this out in a weissbier, but this will have to do for now.

The batch was brewed 2007-06-17.

Were you happy with this beer in the end?

Yes, I liked it a lot. It reminded me a lot of a dunkel weizen, but had a rounded bready flavour from the rye. I still haven't tried any commercial samples yet, so I do not have anything to compare it with.

Of the four beers I had on tap at the time the (it is long gone now btw) roggenbier was thought the best by those trying them.
