Birch Beer aka Pennsylvania Dutch root beer. "made from an old Pennsylvania Dutch recipe" according to the can. Used to drink it as a kid and had almost forgotten about it til a friend dropped off some cans.
Oh man, it hits the spot on a hot summer day, but it's 170 calories and a whopping 41 grams of sugar per can. A very rare treat!

and a semi-related story: I attended a new student mixer at my college in Ohio. Student: where are you from? Lainey: Pennsylvania Student: Are you Dutch? Yes, he asked that as a serious question..!
