They come in 12-oz cans that I picked up for 99 cents a piece. The cans are taller and narrower than standard (I guess for a more sophisticated profile?). Here's a side-by-side comparison with a can of Coke:
The Ginger Cola is noticeably lighter in color with more of an amber tone. It's described as "boldly blended cola made with: kola nut extract, real ginger, sparkling water, and real sugar." There's a surprisingly spicy ginger note at the forefront of this one that peters out into a mild cola flavor.
