When I mentioned that I was interested in aged oolong, he was very kind and sent me some samples, but he kept them a surprise:
"There are four teas in them, including two aged tieguanyin, one aged baozhong, and one aged Taiwan oolong. One of them is what is normally passed on in most teashops as "aged oolong", but is in reality probably just a tea that is a few years old with a lot of roasting. I won't tell you which is which (numbered 1-4) unless you want me to."
"I'd suggesting filling the vessel about 1/4-1/3 full of dry leaves, using the hottest water you can find, and infusing them as quickly as your hands allow, at least for the first few infusions."
Aged Oolong 1
It has a dry cocoa aroma with thick, fruity hints of raisins, dates, or figs; I couldn't make up my mind.
The tea is fairly simple, tastes roasted, light, then after taste of raisins. Thin mouth feel, dry, not sweet at all.
Aged Oolong 2
Much richer aroma. Smells like chocolate, cookie chocolate, not milk chocolate. The aroma brings to mind the word "purple." Don't know why. Some teas smell or taste green; this smells purple.
Again this was a simple tea. Less up front taste but sweeter over all with a sugar cane finish.
Aged Oolong 3
If I didn't know better, I would have guessed this was a puerh. Strong, earthy aroma, deep red liquor, hints of camphor and a smidgen of celery. It had a thicker mouth feel than the others.
Aged Oolong 4
I can't place anything specific in the aroma.
The liquor is "cola" brown.
This tea lacked discernible characteristics or nuances. More astringent, and I tasted a note of celery again, but mostly it tasted hot.
My guesses as to which is which, based on over all feel, taste, and appearance of the leaves, are:
# 1 Taiguanyin. I think this was the "aged oolong" he spoke of.
# 2 Taiguanyin.
Marshal, if you would be so kind to let us all know how completely wrong I am, that would be lovely. And thank you for the samples. I've often been envious of your experiences in China and Taiwan, having access to various tea shops, and it was great to get a chance to sample some these teas.
