I did a SMaSH bock with Hallertauer and Munich 10L, using Wyeast 2308 (Munich Lager). It was great -- very sweet and malty. I did a triple decoction (BIAB), which may not have been necessary. It sure took a while!
i was very pleased with the result. it tasted great before it went into the fermenter. color was coppery and clear as any beer i have ever brewed. it might be one of my best yet. crossing fingers...
