Polar makes one of the only cranberry sodas, under the "Cape Cod Dry" label, which I pick up whenever I’m in upstate NY (I guess it’s distributed through it’s subsidiary company, Adirondack, up there?). When the Wegman’s chain first hit NJ, I could get their store-brand cranberry (possibly made by Polar?) but it was only in 2 liter bottles and they eventually dropped it anyway (in the stores I go to in NJ, at least- and that was one of the only reasons I battled the mobs at Wegman’s- well, cranberry soda, Dr. Brown’s Cel-Ray and Grandma Brown’s beans).
I’m surprised at how many "high end" sodas (still) use HFCS- another favorite flavor of mine is grapefruit and often the only ones on the shelf in NJ are in the "health/natural" food aisle- Blue Sky or Hansen (same outfit, IIRC) and they both use HFCS- I mean, WTF? HFCS in the "natural" aisle?
Jones is another HFCS user – they made a Cranberry around Halloween last year and it was half-price for most of the time it was on sale so I stocked up on it, but it was much heavier and "syrupier" than the Cape Cod stuff- I still have some left and will probably mix it with seltzer.
Briar’s in NJ, best known for the birch beer, has recently joined the "high end" look (4 packs, clear plastic label) but are still using HFCS like Stewart’s.
I’d probably make Boylan’s, with sugar, my constant soda brand but Boylan’s, even tho’ a New Jersey company, doesn’t distribute very well in the central/south part of the state but I was surprised to see it in every little deli, convenience store and even farm markets in the Catskills last fall. Was surprised to see some Hank’s (out of PA., seems to have disappeared from NJ after a big roll out a few years back) Black Cherry yesterday on the shelf so I picked some up.
