Celestial Seasonings Sleepytime Herbal Tea

Founded in 1969 in Boulder, Colorado, Celestial Seasonings is a pioneer in the herbal tea industry. The brand was established by Mo Siegel and Wyck Hay, who began by hand-picking wild herbs in the Rocky Mountains. Their signature 'Sleepytime' blend, launched in 1972, remains one of the most recognizable herbal tea products globally, characterized by its iconic 'Sleepytime Bear' artwork.

While the company went through various ownership changes—including a period under Kraft Foods in the 1980s—it eventually merged with The Hain Food Group in 2000 to form The Hain Celestial Group. Today, the brand's primary manufacturing hub is still located in Boulder, Colorado, where it operates one of the largest tea production facilities in North America and offers public tours of its 'Mint Room' and production lines.

As of 2026, the brand remains a core part of The Hain Celestial Group's portfolio, a leading global health and wellness company. The ultimate owner is headquartered in Hoboken, New Jersey, and manages a wide array of natural and organic product brands across international markets.
