By TTNews Reporter Tsai, Cong-Ting TAOYUAN, TAIWAN (TTNews) – Suan-gang is a type of citrus that has a red-chromatic appearance and extremely sour taste. It is generally used as a decoration instead of being consumed as a fruit due to its unpleasantly sour taste. Suan-gang is also characterized by its enormous shape which is twice the size of regular citrus fruits. Suan-gang can remain its fresh look for few weeks; thus, it has become an extremely popular item to be set on the table in use for worshiping the deities and ancestors. However, people would usually toss them away after a while since they are not suitable for consumption. Hakka people are known for their thrifty characteristics and they simply just cannot stand for wasting food. Eventually, they come up with an idea by producing suan-gang tea. To produce suan-gang tea, the entire production process is quite complicated and time-consuming. Not to mention that the practice of each factory may vary differently. Sometimes, even the results of moldy or rotten finished products are inevitable. The aged suan-gang tea is charcoal black in color and has a pleasant fragrance when brewed. Before brewing, it is required to chop into smaller pieces. Some of the tea shops would provide the aforementioned service. A steaming hot cup of suan-gang tea tastes amazingly soothing and refreshing.
