I started drinking this many years ago when it was labeled “Formosa Oolong.” It’s remained one of my favorite teas, even when it was relabeled “China Oolong.”
It has a light, slightly peach flavor.
Unfortunately, I think Twining stopped carrying this as a loose tea, although it is available in bags.
After years of searching, I
finally found a loose tea that has the same flavor. It’s sold by Old City Coffee in Philadelphia as Taiwanese Oolong, and they do ship although it’s more expensive than Twining or buying from their stores.
