USDA organic. Just a tad sweet. Yes, our mates are sublime, but we didn't name this tea after our wives. Actually, the word mate is pronounced Mah-tay. Traditionally this South American energy drink involves brewing the dried herb (yeba) in a ground (mate), which is ceremonially passed around and shared by close friends. We blend our organic yerba mate with organic limeade and a dash of ginger for a low-sugar, high-energy treat you can enjoy anywhere-with or without ceremony. Honestly yours, Seth & Barry. PS. Yerba mate is rainforest-friendly-it can be grown as a shade plant and helps form the basis of a sustainable local economy in Argentina. Gluten free. No GMO's. Contains 3% juice.
