Thanks for the recipe, Bryan! I've always used Dark Munich and Pilsner malt in my dunkels at about 80:20 for my base malt, mainly because the flavor and aroma of the Dark Munich is what I'm looking for. But my results have always been a bit "meh". "Too rich" isn't exactly how I'd describe it, but it's close. I'm thinking that the 50-50 blend of Munich malts will go a long way towards fixing that. That, and I'm also targeting a lower pH on my lagers since last I brewed a Dunkel.
Coinsidentally, this recipe is really similar to my Märzen, except I'm using Light Munich & Vienna 50-50, rather than the two munich malts.
