Zairai black tea is sourced from the pristine Yakushima "Medicine Island" in Japan. This tea is made from indigenous tea plants grown without any chemical fertilizers or pesticides harvested in 2023. The island's rich volcanic soil and temperate climate give this tea a unique flavor profile. With a smooth and robust taste, Zairai pours a healing cup of tea, letting its aroma and flavor transport you to the serene Yakushima Island.
