100% Natural Teas Naturally Caffeine Free Kosher Gluten Free Blendmaster's Notes "There's no mistaking a Zinger! We introduced Red Zinger in 1972, and nothing around here has been the same since. The zing comes from a blend of tart and tangy Chinese hibiscus and fruit Thai hibiscus, balanced by cool, refreshing peppermint and the unique, earthy sweetness of wild cherry bark. Try this perennial favorite on ice!" — Charlie Baden Celestial Seasonings Blendmaster Since 1975 Our Natural Heritage In 1969, Celestial Seasonings began picking fresh herbs in the forest and canyons of the Rocky Mountains and blending them to create healthy, flavorful teas. This tradition of turning the best of nature into delicious taste experiences continues to this day.
