Thai Oolongs rival the best oolongs from China and Taiwan in both taste and style. However, they are hardly known by tea connoisseurs. Tea production in the high mountains of Thailand was established in the 1980s by Chinese immigrants. What began as small economic activity has grown to a strong community of independent tea gardens. Select lots have been sold through some of the finest shops in Europe, and now this style of tea is being introduced in the U.S. tea market.
