About Oolong Tea
Oolong sits between green and black tea: its leaves are partially oxidized, anywhere from lightly (closer to green tea) to heavily (closer to black). Many oolongs are also roasted over charcoal or in ovens. Most come from China's Fujian and Guangdong provinces and from Taiwan, with well-known styles including Tieguanyin, Da Hong Pao, Dan Cong, and Taiwanese high-mountain oolongs.
What it tastes like
Lightly oxidized oolongs are floral and creamy, with notes of orchid, lilac, or butter. Darker, roasted oolongs taste of stone fruit, honey, toasted grain, and minerals. Many leave a lingering sweet aftertaste.
Other ways to brew Oolong Tea
In a mug or teapot
Use one to two teaspoons (2–3 g) per 8 oz (240 ml) cup; tightly rolled oolongs look like less than they are. Heat water to 185–203°F (85–95°C) and steep 3–5 minutes. Green, floral oolongs want the cooler end; dark, roasted ones want water close to boiling. Give the leaves room, since rolled oolong can expand to several times its size.
Gongfu style
This is how oolong is traditionally brewed: about 5–7 g of leaf in a 4 oz (100–120 ml) gaiwan or small clay pot. Rinse the leaves with hot water and pour it off, then steep 20–30 seconds, pour out completely, and repeat. Add 5–10 seconds each round. You'll get six or more infusions, and the flavor shifts as the leaves open.
Iced oolong
Brew double strength, about 5 g in 8 oz (240 ml) of hot water for 4 minutes, and pour over ice. Roasted oolongs make an especially good iced tea, nutty and smooth.
Cold brew
Use about 5 g per 8 oz (240 ml) of cold water and refrigerate for 8–12 hours. Cold-brewed green oolong is creamy and floral; roasted oolong turns toasty and sweet. Rolled leaves open slowly in cold water, so give them the full time.
Can you re-steep Oolong Tea?
Oolong is the best tea there is for re-steeping. In a mug, good whole-leaf oolong gives three or four infusions: steep the second for about a minute longer than the first, and add a minute each time after that. Brewed gongfu style it can go six to ten rounds. The first steep is often the least interesting, since rolled leaves take a round or two to open.
Ways to drink Oolong Tea
Green, floral oolong
Lightly oxidized teas like Tieguanyin and Taiwanese high-mountain oolong are floral and creamy, with notes of orchid and butter. Brew them at about 185–195°F (85–90°C).
Dark, roasted oolong
Heavily oxidized or roasted teas like Da Hong Pao and traditional Tieguanyin taste of stone fruit, honey, and toasted grain. Use water near boiling, 200–203°F (93–95°C).
Milk oolong
Jin Xuan, or milk oolong, has a natural creamy, buttery character; some versions are also flavored. Brew it like a green oolong.
