From their website:
"What is this ting !
(Grapefruit Soda) Ting, made from Jamaican grapefruit with no preservatives is the ultimate thirst quencher. It is a lightly carbonated citrus drink.
This carbonated drink with the green and yellow label is the unofficial national soft drink of Jamaica. It is quite simple and all apologies to "aranciatta, the greatest non-alcoholic summer beverage, full stop. Sure there are cheap imitations, but they are just that.
The drink is unstoppable on ice. It goes nice with the hard stuff, the universal deadly Sin Ting will set your teeth chattering.
Ting - the Jamaican sunshine and cool breeze in a bottle."
I had my first Ting in the BVI and I have been on a quest to find it in New England for nearly a year. It is great with rum, vodka and tequila or just plain with ice. I don't want to mail order it but I will drive anywhere around greater Boston or New England to pick some up.
