Oolong vs Green Tea

Oolong and green tea are both famous Chinese teas, but they differ in oxidation, flavor, caffeine, and brewing. Learn which one suits you.

Oxidation Is the Main Difference

Green tea is unoxidized, giving it a fresh, grassy, and sometimes nutty profile. Oolong is partially oxidized, ranging from light and floral to dark and roasted.

Flavor Profiles

Green tea tends to be brisk, vegetal, and clean. Oolong offers more complexity, with notes of orchid, cream, fruit, toast, or minerals depending on the style.

Caffeine and Body

Oolong generally has a fuller body and can be higher in caffeine than most green teas, especially darker roasts. Green tea is usually lighter and more refreshing.

Brewing Approach

Green tea likes cooler water around 75–85°C. Oolong can handle hotter water, often 90–100°C, and rewards gongfu brewing with many short infusions.
