The Keweenaw Brewing Company is in South Range, Michigan. The beer takes its name from a pneumatic drill that operated without water to lubricate the bit and cut the dust. It was introduced in 1870 for copper mining. It improved productivity, but the dust killed many miners from prolonged exposure to dust inhalation. With that happy note, we move on to the beer.
The beer pours coal black in color. There is a short head of very light brown foam. The aroma is dark roasted malt, a bit of coffee and both sweet and tangy notes. The taste follows the aromas, very dark roasted malt, a hint of char, a touch of coffee, and both a sweet and tangy note on the finish. It is nicely carbonated, but drinks just a tad watery. That is its only drawback, because the flavor on this is excellent. It drinks light,but tasty, like a light porter or dry Irish stout. I put this in the "dangerously drinkable" category.
