tried it twice so far in the usual 180 ml duan ni pot.
first time was outdoors on hot day with a 5-6 g piece from center of cake using spring water.
second time was in office with filtered tap and using un-weighed piece towards outside of the cake.
1.first few steeps were very floral.
2. first few steeps had a milky color.
3.dry leaves after first rinse smelled like night queen http://en.wikipedia.org/wiki/Epiphyllum_oxypetalum
4.sensation of strong wave of fresh energy coursing through upper body immediately upon first sip.
none of the 4 characteristics above occurred during the second session.
Going to experiment more with this one and will update results here.UPDATE: tried again in glass pot. none of the milky color or floral aroma of first session. this one is is still young for my tastes. hoping that a few hot humid israeli summers will mellow out the cake and bring out some riper flavors. Ever since I sampled a few 12+ year old shengs I am not in a hurry to drink anything younger.
EDIT: after experimenting a bit more with this tea, my conclusion is that the flavor/aroma are too light for my tastes. On the plus side, it has a certain amount of qi to it. I will put the rest of the cake aside for to age for another few years and hope for the best.
