The Munich lager strain is a notorious diacetyl producer. Scrub the butter with a diacetyl rest, the brief fermentation rest at 60°F. The yeast transforms diacetyl into the flavorless chemical, butanediol.
Märzen is German for March, the last month of brewing before the legally mandated summer hiatus. Developed in the 1840s, the original versions were strong and copper brown. Aged for the summer in the lagering caves, this was the original beer of Oktoberfest.
The Munich dunkel took advantage of the water, piling on darker malts to make a deeply brown beer with toffee, caramel, and nutty flavors. As the style travelled around Germany, it took on different hues. Out of this was born the schwarzbier. The modern schwarzbier is as dark as a porter, but without the acrid roast character. The beer finishes dry after a faint caramel toffee flavor. This is the application for Carafa dehusked malt. It gives color and soft roasted-coffee tones with toffee flavor.
