Instant turmeric ginger green tea is finally here! Matcha tones down the spice of the turmeric, ginger and cayenne in Jahmu. Each serving has one teaspoon of organic coconut sugar, giving this tea a subtle sweetness while only adding 5-10 calories to your diet. Each cup of Matchai has about 20 to 40 mg of caffeine. You'll get more caffeine if you drink the last sip which will have some undissolved green tea.
