An Authentic Milk Oolong

Nai Xiang, literally “milk fragrance” is a characteristic of a Taiwanese high-mountain oolong made with the Jin Xuan cultivar of camellia sinensis. Jin Xuan is known not only for it’s milk-like mouth-feel, but also for it’s cream like flavor and aroma.

Many so-called “milk oolongs” have popped up on the market having been artificially flavored. In 2010, Roy Fong, owner of the Imperial Tea Court traveled to Taiwan and  discovered several variants of it’s production. From what he discovered, I am seeing three different things all being called “milk oolong” in order of legitimacy:

  1. True Jin Xuan oolong with natural creamy mouth-feel.
  2. Jin Xuan grown with a home-brew fertilizer made from milky substances.
  3. Artificially flavored milk-oolong, flavor added after initial processing.
Roy was able to see the home-brew fertilizer being made and described it as a “solution of egg, milk powder, soy bean meal, fish meal, honey, and yogurt that they fermented and used as liquid fertilizer.” Here are some photos that he shot:

So how do you tell if you have a true milk oolong? I think that if you have experienced one with an overwhelming aroma and flavor, it was likely artificially flavored. Another way to spot artificial flavors in tea is to note if the flavors last from steeping to steeping or if they diminish after one steeping.

    Looking forward to that U.S. based site because you have a lot of products that I want, but would rather not pay for the long trek from China. Thanks for the info.

    it sounds like something I’d like to do a taste test with my friends and throw up the video..just to hear their reactions to it!

    Is it a high mountain oolong? They tend to have a certain silkiness, but I wouldn’t describe the mouth-feel as creamy. I’ll have to get some of this stuff to check it out.
