Had as a pour in Portland and I have to say it was one of the more interesting beers I have had in some time! Description on the menu: "Tart, dry, and delicious. Brewed with 1400 pounds of Maine cranberries!"
The pour was a hazy cranberry-reddish color and a bit of foam lingering around. Most importantly the scent was strongly cranberry with a bit of tartness on the nose. Much to my surprise, I was expecting an acidic and sour flavor but instead found a dry and tart cranberry flavor instead. The tartness itself lingers on the tongue, while the whole beer itself was surprisingly drinkable. Would recommend trying if you run into it!
