It's very real, and Jones is a very cool soda company. They have a penchant for offbeat flavors... many of questionable drinkability. Turkey and Gravy is said to have a quite authentic flavor... but I've not been brave enough to actually try any yet. :) Their Green Apple is really rather good, as is most of their non-gimmick flavored drinks.
Jones Soda
They also have a Christmas Ham flavor, and a Hanuka gift-pack.
Jones also has the coolest labels out there. Most are photos customers submit to them - and they rotate them frequently.
