Infrared Gu Shu Hong Mini Bing (古樹紅小餅, Gǔ Shù Hóng Xiǎo Bǐng, "Ancient Tree Red Little Bing") - Gu Shu Hong simply means Ancient Tree Red. Nannuo Mountain is famous for having an abundance of ancient trees, some of which are estimated to be as old as 800 years. This tea is made from ancient trees on Nannuo Mountain that have been processed into a distinctive shài gān hóng chá 曬乾紅茶 ("sun-dried red tea"). This technique involves gently massaging the leaves (揉捻, róu niǎn) and allowing them to wither and oxidize, alternating between sun and shade, to achieve complete oxidation before the leaves dry out completely. It's a delicate process that requires constant attention, but the resulting fragrant red leaves convey the unalloyed character of the tea, because there was no cooking involved. When applied to the prized ancient tea tree leaves, this process captures, in a very naturalistic way, the full expression of the plant.
This mini bing includes 100g of pressed tea. The base color of the wrapper is red, indicating that it is a Red Tea. The ring and bat are gold, indicating that this tea is made from Gǔ Shù 古樹 ("Ancient Tree") leaves. This means that all of the leaves that went into this tea come from trees that are at least 100 years old.
