After doing a little research I learned that He Huan Shan is located near Lishan (梨山) in central Taiwan. Its main peak is 3,416 metres (or 11,207 feet) high and it is one of only a few peaks in Taiwan to receive snow. He Huan Shan tea is generally produced between 2000 and 2400 meters which is considered very high elevation and excellent for oolong tea.
The dry leaf:
I have been enjoying this tea immensely. It has a very clean taste. My wife, who has a great palate for high mountain tea, likened the flavor to Lishan high mountain tea (which is often our mutual favorite). She said it was buttery, fruity and had good hui gan (回甘) which means lingering sweet aftertaste, and I would absolutely agree. The aroma of a freshly poured, steaming hot cup of this tea will start off with a milky, malty, vanilla aroma but as it quickly cools the aroma will completely change, morphing into a much brighter "apple candy" and "sugar cane" smell. The color of each infusion is a deceptively light yellow and the taste is quite unique. Some flavor notes that I picked up in my last session included: alpine meadow grass, toasted grains, and sparkly yeasty beer. This particular Taiwanese tea, unlike some other high mountain oolong teas, does not seem to have any floral notes, which can be a very nice change of pace if you're not craving a flowery brew. I have recently been brewing this oolong in Desmond and if Desmond is filled about 1/4 full of dry leaf I will easily get 15 great infusions!
