I have no clue what this or that famous Sheng is supposed to taste like. I haven't had the opportunity to drink fabulously expensive ancient Pu Erh's. But I do like the taste of aged sheng far more than fresh sheng.
What i am drinking are my own home stored teas. My oldest home stored teas are from the late 90's and 2000/2001/2002. I bought them in Malaysia at the time. I don't remember where they were from, just that they were boutique teas, and are very very nice. It was lovely to follow their aging process, when i began drinking them in 2008. I still have enough cakes from then left to last me two years at least. And by then some of my other teas will be ready.
For many years i haven't bought Pu Erh anymore, but began buying in 2008 again (mostly teas from 2004 and 2006 onwards). At times i nip at my teas, to see how they develop. A few teas i am not so happy yet (mostly big factory blends), but some others i am quite confident that they will develop into something very nice, such as Yunnansourcing's 2009 "Wu Liang Lan Xiang", which i had a pot a few months ago, and which develops into something very complex. Another tea, which i bought from Yunnansourcing in 2008 or 2009 that i liked a lot a year ago when i tried it last was the 2003 CNNP "Yi Wu High Mountain Wild Arbor".
I have other teas other than i have from Yunnasourcing, which i bought in Malaysia, or here and there.
Aging has a lot to do with climate. When i tried ten year old teas from Kunming, they often aged less in ten years than comparable teas here in my home in Bangkok in 2 or 3 years. That is my comparison. I am not an expert in Pu Erh, or aging Pu Erh, i just make do with what i can afford, and what i have. And so far, i like a lot what i have
I safe also a few of my cakes, so that one day i can have some proper 20 year old cakes (some of them won't even take that much longer, i realized with horror when just writing this down...i am i that old already...?
I don't aspire to become a Pu Erh master. I just like my teas. I buy mostly for the future, mostly look for teas that i feel have promise. Once a while i buy a cake or two from semi-aged teas, when they are not too costly, to stretch out my better teas, and to bridge over the time until the teas i bought later will be ready. I think that right now i have a 20 to 30 year supply. From now on i will buy a lot less, but then maybe more expensive cakes. I just won't need that much tea anymore, and i have no idea if my son will enjoy tea when he gets older.
I haven't had any disaster (knock on wood...), but i smell them regularly, and shift them once a while. I have done OK with my first cakes in this way, and why fix it when it's not broken.
