Oolong is one of the most time-consuming teas to create. It utilizes all of the five basic steps, with rolling and oxidizing done repeatedly. These teas are anywhere from 8% oxidized to 80%. You can tell by measuring how much brown or red is on the leaf while the tea is being made.
The leaves are gently rolled, then allowed to rest and oxidize for a while. Then they'll be rolled again, then oxidized, over and over. Over the course of many hours (sometimes days), what is created is a beautiful layering or "painting" of aroma and flavor.
Oolongs typically have much more complex flavors than Green or White teas, which very smooth, soft astringency and rich in floral or fruity flavors. Because of their smooth yet rich flavor profiles, Oolongs are ideal for those new to tea drinking.
