I did not buy them, these are Shengs from private collections that tea friends bring in to the shops for evryone there to enjoy. Every now and then someone drops in and says to the owner "I just dug this out of my collection, I think it is just about at it's peak, what do you think?"
Of course if I am sitting round the table with the owner then I get to try them also. The owner usually then selects one of his own aged teas for comparison.
There are some aged ones to buy 1000RM a bing or more
No - I have been buying Sheng both in Malaysia and online, to drink a long time from now, if I run out of Oolong I can always break open a Sheng to see how it is doing!
