Late reply to an old thread.
Who's tasted it?
I have, I have.
Saki Soda was a promotional concept in the US about 1975-6. Tom's Kawasaki (Tom Luthi) in Perryton, Texas was the only distributor that I know of and the drink was stocked there and sold by traveling Saki Soda guy Rocky Morris (now deceased). The drink was green in color and tasted of lemon/lime... at least for a while. Because it was a slow mover, in time it began to take on the metallic taste of the cans and ultimately several tons of the stuff were buried in the sanitary landfill in Perryton. It really wasn't half bad, but it just didn't catch on.
Wes Anderson was the general mangaer for Tom's Kawasaki during those years and the shop ceased doing business about 1977 I believe. Tom also had a shop in Guymon Oklahoma for a brief period.
