The base of this product is fermented fireweed, which is a naturally caffeine-free herb. The description clarifies that it is positioned as a caffeine-free herbal tea, making it suitable for those avoiding caffeine later in the day.
You may notice a "Nepalese black tea note" listed as a component. This refers to an aromatic element used to enhance the blend's depth and complexity, not necessarily the addition of Camellia sinensis tea leaves that would contribute significant caffeine. In herbal tea blends, such notes are often achieved through flavoring or the inclusion of small amounts for aroma without substantially altering the caffeine-free character. If you are highly sensitive to caffeine, it is sensible to check the full ingredient list on the product packaging for complete details.
