Brewed a maple porter yesterday. It was intended as a pale ale when I gathered the ingredients, but a coworker/fellow homebrewer gave me a gallon of maple syrup that had been overcooked at the sugar farm, and when he said overcooked, he wasn't kidding. It was probably 180L or so in color, so 6oz turned a 1 gallon pale ale into a porter, fast! Roasted/toasted flavor, very dark color. The syrup itself looked like motor oil, and the beer has a deep reddish-brown color. Looking forward to tasting this one!
