pu erh and white aged tea.
Yes, it is.
What's important to note is that aged white teas often have an addition step of steaming. This makes the leaves soft to allow them to be compressed into cakes for aging. I would describe the taste as follows:
- New white tea: fresh & floral
- 2-5 year old white tea: fruity & smooth
- >5 years old: thick texture, herbal medicine
