What is oolong tea?
Oolong sits between green and black tea — partially oxidised, which means somewhere between the fresh, grassy character of a green and the deep, malty richness of a black. The range within oolong is extraordinary. A lightly oxidised oolong (10–20% oxidation) tastes floral and almost green, think orchid, jasmine or stone fruit. A heavily oxidised, roasted oolong (60–80%) is dark, complex, and warming, with a caramel depth more like a very good black tea.
The processing is skilled and deliberate. After picking, leaves are withered in the sun, then repeatedly rolled and tumbled to bruise the edges and drive oxidation. The degree of rolling, oxidation, and any roasting determines exactly where the tea lands in that vast spectrum.
Oolong and the New Zealand palate
Oolong works particularly well for coffee drinkers exploring tea. The deeper, roasted styles have a similar sense of body and complexity, the kind of cup that holds its own without milk. The lighter, floral styles offer something else: jasmine-scented infusions that show how far from a flat breakfast tea can go.
Oolong is also one of the most re-steepable teas. Quality loose-leaf oolong can handle 3–5 infusions, each releasing different notes as the leaf slowly opens. A single measure of good oolong is a more generous investment than it might first appear.
