Since McDonald's coffee brand McCafé announced increased investment in the Chinese market, its number of stores has surpassed 3,200. Its "store-within-a-store" model is equipped with semi-automatic espresso machines and dedicated baristas, focusing on a specialty coffee approach.

In tea leaf harvesting, besides the common one bud with two leaves and one bud with three leaves, there is also a classification based on the degree of opening of the new shoot's terminal bud: unopened, small open-face, medium open-face, and large open-face. The purpose of open-face picking is to enrich the tea's internal substances, thereby improving the quality of the finished tea. Different degrees of opening correspond to different levels of maturity, affecting the difficulty of leaf processing and the flavor of the finished tea: older leaves are easier to process, with a mellow taste and high aroma; tender leaves are harder to process, prone to a bitter aftertaste but with a strong flavor and good durability for multiple infusions. Oolong teas such as Phoenix Dan Cong and Tieguanyin have their own preferences for open-face standards, and high-quality black tea raw materials often use open-face leaves as well. In this article, Front Street Coffee combines changes in tea chemical composition to clarify for you the differences in picking standards between Tieguanyin and Phoenix Dan Cong. [more…]
