Drinking very masculine Java tea

Have had a lot of tea grown on the Pasir Nangka tea estate in Java lately.

Wrote about Java Santosa last year (Startles me awake), and I still like tea from this region. This one might even be better than the earlier one. Maybe.

This one is strong like a good Assam, but not a lot of tannic acid. So it's not at all bitter. That's why I like to use Java tea in blends of black teas. There's something fruity and spicy in the taste as well.

Did a bit of research about tea from this region, and what I learned is that they started out planting tea plants from China here in Indonesia. For some reason, they switched to tea plants from Assam at some point.

Am rather curious why tea grown from the same plant, but grown in an entirely different region, has such a dramatic difference in taste. Any thoughts on that one?
