Abstract: Among the four major categories of oolong teas, the Northern Fujian Oolong is produced in the jurisdiction of Nanping City in the province. This article updates the research progress on the formation of the exquisite flavor of the tea. Any attempt to further improve and accentuate the characteristic flavor of the Northern Fujian Oolong, an in-depth understanding of the formation of the underlining chemicals related to the aroma and taste of the tea is essential. Consequently, factors affecting the formation, mechanism, and deviations on the chemical makeup that determine the sensory quality of the tea, such as plantation environment, cultivar variety, processing technology, and storage conditions, that were explored and reported recently by researchers are summarized.
