The winter seasonal from Magic Hat Brewing Company in Burlington, Vermont, is a black lager called Howl.
Howl is an intensely dark black beer with just a hint of caramel brown at the thinnest part of the glass. The creamy head is a dark buff color. Some roast malt and a little caramel are all I get from the mild aroma. Inviting, but not revealing.
The flavor is clean, dry, and malty. Roast malt character like burnt toast is key, with just a hint of sweetness and plenty of robust lager character. Finishes dry and drinkable. The roast character is restrained, the malt flavor dry, and there is no detectable sulfur: this is pretty much the ideal execution of a black lager.
