Tazo Orange Chiffon Full Leaf Tea Orange peel and buttercream pirouette with vanilla into a dancing cloud of creaminess choreographed by Earl Grey himself. Black Tea Black tea is the fully oxidized leaf of Camellia sinensis and requires the most processing. The brewed liquor ranges between dark brown and deep red. Black teas offer the strongest flavors and, in some cases, the greatest astringency. A Richer Tea Experience The wonders of our full-leaf teas begin with the thoughtful design of our sachet. The water is able to flow freely over the leaves, allowing the distinctive flavors to unfurl and reach their full potential in your cup.
