The nation’s leading producer of herbal teas, housed in a modern building in northeastern Boulder, offers tours that are an experience for the senses. The company began in a Boulder garage in 1969 and now steeps in more than 1.6 billion cups of tea a year, sourcing more than 100 different herbs and spices from 35 countries. You’ll understand why the company invites you to “see, taste, and smell the world of Celestial Seasonings” as you move from a consumer taste test in the lobby to their famed tea-box art, and finally into the production plant where millions of tea bags are made daily. The exhilaratingly aromatic “Mint Room” is a highlight. The tour lasts 45 minutes, and there is a cafe and gift shop on-site.
