Investing in Tea

Anyone wants to invest in tea? More and more people are choosing to invest in tea these days, especially Pu Err tea as the prices of tea (good quality, superior tea) have been going up steadily for the last few years. In fact, the price of tea has gone up even higher than the price of gold. The older the tea is, the more price it will fetch. Unbelievable eh? I also find it hard to believe but I've been reading it from the internet and from the papers very frequently these days.
