One of the oldest organic tea estates in the world, Luponde sells its leaves inside this small shop in London’s Mayfair neighborhood. Located in Southern Tanzania’s Livingstonia Mountains, the estate grows full-flavored organic and fair-trade tea leaves. The leaves are then handpicked and placed inside snappy black canisters to be sold in-store. Inside the shop, tea lovers can smell and feel the leaves before purchasing, and the selection includes everything from black teas to green tea to fresh chamomile tea. Various gifts and teaware are also available.
