A dark oolong tea that only grows in the rocky soil of China's Wuyi Mountains, this drink's legendary robust sweetness and lingering woody notes make it special. While reasonably good quality tea not from original trees can be bought for around $100 per kilogram (2.2lbs), aged and antique versions can reach eye-watering prices. Back in 2002, a collector was willing to shell out almost $28,000 for only 20g (0.7oz) of tea from one of the original mother trees, meaning a kilogram (2.2lbs) would cost $1.11 million.
