In this video, I show you how to brew a Munich Dunkel at home using a double-decoction process. This beer has rich malt flavor with notes of toasted bread and subtle chocolate. I love this beer for any time of year, but there’s something special about this one during the Fall/Winter months. I’d love to know what you think about decoction mashes—do you think they’re worth the extra effort?
