Found this stuff while driving to NY in a market north of Scranton, PA off of I-81. Had never heard of Crystal Club sodas, and more than likely won't find this stuff outside of the Northeast PA area since the labels says "Crystal Soda Water Company, Scranton, PA." So this is truly a local flavor unless someone tells me that they found it in NY or NJ as well.
Not that I'm really itching to get some more of this though. It says "root beer" but it tastes more like birch beer to me. Has a good amount of bite, doesn't make much of a head and none too sweet. Still, for the price, I would take this over the big brand root beers (A&W, Mug, Barq's) anyday and most definitely over the generic store brand root beers you'd find in large supermarket chains.
Sweetened with: "Corn Sweeteners"
Verdict: Worth a can/bottle or two
