Have you tried Matcha? It's Japanese green tea and it's powder, so yo prepare it kind like coffee (you don't use a tea box). Apparently it' great for your health and also for concentration and energy boost. Grea for coffee drinkers, yoga lovers and anyone looking for a healthy energ drink during an intense day.
If you prefer high quality tea (for drinking only) try 'Matcha Green Te Powder |*Breakaway Matcha'
What is your opinion on matcha? for drinking, cooking or both
