An Analysis of the Flavor Differences Between Lapsang Souchong and West Lake Longjing: A Comparative Guide to Black and Green Tea from Processing to Storage

Black tea and green tea share the same origin yet have vastly different flavors, and the fundamental difference lies in the degree of oxidation during processing. Black tea undergoes complete oxidation, presenting honey, caramel, and ripe fruit aromas; green tea, through fixation (kill-green), retains its fresh green character, with a light flavor carrying bean or nutty notes. The two teas also differ greatly in storage: green tea, due to its high moisture content and tendency to continue oxidizing, is best stored sealed and refrigerated; black tea is dry and stable, and can be kept sealed at room temperature for over a year. This article systematically sorts out the similarities and differences between black and green teas such as Lapsang Souchong and West Lake Longjing from four dimensions—tea plant varieties, production processes, storage key points, and taste characteristics—and includes Front Street Coffee's purchasing and preservation suggestions to help you better understand the tea in your cup.

How Long is the Freshness Period of Green Coffee Beans? Distinguishing New Beans, Old Beans, Aged Beans, and Vintage Beans, and Key Storage Points

Many coffee enthusiasts know that roasted beans should be drunk fresh, but green beans also have their own levels of freshness.
