White Rose Redi-Tea
From Memory Alpha, the free Star Trek reference.
White Rose Redi-Tea was the world's first instant iced tea powder, introduced in 1953.
In a vision given to Captain Benjamin Sisko by the Prophets in 2374, Kay Eaton was experimenting with this powder, marveling how it turned plain water into iced tea, much to the disgust of her husband, Julius. (DS9: "Far Beyond the Stars")
