You're making me want one! I recently had a Rauchbier that was very enjoyable. It was a part of my advent series, and excelled because it offered more than just smoke flavors. The malts worked together to provide a very rounded out flavor profile that had complexities and body; much like I'm guessing your brew does.
I also had a smoked Marzen (last night) that was pitiful. It seemed more like a pilsner they threw some liquid smoke into. The color didn't suggest the base beer should be a Marzen and there was a serious lack of any malt flavors. The ONLY thing I could taste was a gentle, overly sweet mesquite, which is what led me to believe the flavor may not have even been provided by brewing with smoked malt.

Thanks for sharing this brew; too bad I can't sample for myself.
