London Tea Exchange puts quality and fair-trade principles at the heart of everything it does, crafting luxury teas from only the finest single-estate ingredients. The walls of its Brick Lane store are lined with shelves of what appear to be beautifully bound tomes, but which are, in fact, the Nobel Collection - book-inspired tins that echo the precious nature of the premium tea quartet inside. Volume III is the Oriental Collection: the light, nuanced Emperor's Green, the smooth and exceptional Jinxuan Oolong, the entirely hand-crafted, creamy Milk Oolong and the fragrant and aromatic Flower of Asia.
