Fans of mamaki tea understand that it gets better with age. Allowing the leaves to steap throughout the day (or for several days) coaxes out evermore antioxidant nutrients. So Aquaovo’s Thermo-O Terra double-walled water bottle with tea filter (let’s just call it a tea thermos) made perfect sense when I saw it.
Throw in some leaves, fill it with boiling water, and take it with you. Sip throughout the day. You last sip will be your most nutrient-rich.
