Founded in 1969 as the first company focusing on herbal teas, Celestial Seasonings has grown to become the largest in North America, producing well over a billion cups of tea every year. While the herbs for their first teas were harvested by the founders themselves from a secluded canyon in the mountains of Colorado, Celestial now sources more than a hundred different ingredients from nearly 40 countries. Fifty years on, they still make sure that all their teas are beneficial for their customers and for the environment, they still put lovely hand-painted illustrations on all their boxes of tea, and they still have their headquarters in Boulder, Colorado - on Sleepytime Drive, named for their flagship tea.
