I've reviewed two of the teas from Indonesia, and tried two others, but nothing was really exceptional. I kind of expected that because it didn't seem like I found the best sources of specialty teas in what I happened to cross paths with, but some of the teas were interesting. Those posts:

The Indonesian white tea had a lot of smoke to it, not really sure why, but it took over the flavor and made it harder to judge. I bought a second silver-needle style white tea (buds only, technically not silver needle per on take on the naming convention I've ran across), so I'll see.

This green tea I bought wasn't exceptional as green teas go, just interesting for being a little bit different. It doesn't help that I don't love green teas as much as others to begin with, and the profile I do like in green teas, around that of Longjing, wasn't how the tea came across.
I also tried a very commercially processed black tea, essentially ground tea, which was quite astringent but ok beyond that, really only ok with milk and sugar given that aspect. I bought that directly from the Wonosari plantation so I'd hoped it would be a little better, one step closer to a specialty tea.
I bought a few really commercial grocery store teas, just gambling to see how they worked out, and only tried a jasmine black tea so far. That was actually pretty good, exceptional compared to how it looked, with a mix of tea, tea powder, sticks, and some flowers. For a purist high-end tea drinker it might seem undrinkable but to me it was nice for an everyday tea, with very limited astringency, decent flavors, earthy with a little mineral and a bit of sweetness, with reasonable balance. The level of jasmine was nice, not strong, complimentary for being subtle. Given the price the tea was fantastic; I don't remember the exact cost but it was in the range of a dollar per 50 grams of tea.
The final verdict is that it's not so easy to travel in a foreign country and let chance lead you to the best teas, and you can only stack the deck so much in advance with online research. It's interesting trying the teas, interesting looking for them, definitely interesting seeing tea grow at a plantation, but to buy the best teas it's as well to do extensive online research and order them by mail. Of course there are exceptions; a place like the Kunming tea market would have a crazy selection, and walking around any city in China is a completely different thing that SE Asia, or even Japan.
