Oolong teas are in between a green and a black tea in regards to processing/oxidation time.
Oolongs are often fire roasted lending to a toasty note. In many cases an oolong tea will be “rinsed” before it is steeped to wash away the roasted flavor note. This is to expose the sought after floral characteristic. Oolong tea is the preferred tea of the Orient for metabolism, weight loss and appetite suppression.
