The farmer was sidetracked after a long day of tea selecting and upon returning to his withering tea leaves he discovered they had actually currently started to oxidize. No matter which story you believe, it holds true that the most famous chinese oolongs are grown in high mountainous areas over rocky terrain and in cool weather condition.

The styles of oolong produced throughout the nation differ just as much as the designs of white wine that come out of france.
