Gluten free. Caffeine free. Great hot or iced! Blending herbs, art and inspiration since 1969. Blendmaster's Notes. Lemon Zinger: In this classic brew, we blend real lemons and lively lemongrass with hibiscus, the vibrant tropical flower that gives all Zinger teas their signature tangy taste and ruby-red color. It's a bright tea that's perfect in any weather. - Charlie Baden, Celestial Seasonings Blendmaster. The Story Of Celestial Seasonings: Back in 1969, we started picking herbs from the fields and forests of the Rocky Mountains and in the process, we created America's very first herbal tea. Still blended in Boulder by our expert Blendmaster, our uniquely delicious teas are made with the finest ingredients, passion and inspiration. But the fruit that can fall without shaking Indeed is too mellow for me. - Lady Mary Wortley Montagu. celestialseasonings.com. Tell us what you think: 1-800-351-8175; celestialseasonings.com.
