Common questions
What is FOS?
FOS stands for fructooligosaccharides, a plant-based ingredient. The FOS in this tea is sourced from beets and has a mild natural sweetness.
How much caffeine is in prebiotic black tea?
Approximately 30 mg per 1 teaspoon serving. For comparison, Waka's regular instant black tea is about 35 mg per 1/4 teaspoon, and Waka instant coffee runs 45 to 80 mg per serving depending on roast.
Does FOS affect the taste?
FOS is mildly sweet and neutral in flavor, so it tastes like black tea.
Can I make it with cold water?
Yes. The prebiotic teas mix in cold water directly, so you can make iced tea or a pitcher without brewing hot first.
Our Prebiotic Tea Powder is concentrated, so a little goes a long way. Use 1 teaspoon per 8 fl oz serving. Pour powder into cup, stir until fully dissolved and enjoy hot or iced.
