This tea seems to be universally loved so I will be a contrarian in my review: I did not like it that much. I prepared it western style. The wet leaf aroma was very good: grass, spice, some hints of green vegetables and butter.
The taste story was altogether different. It is a finicky tea: my first steep proved to be too long or hot and it resulted in a very grassy and bitter product. The other steep proved to be too short so the tatse was rather bland. Only my third steep hit the fine balance and I did get all of that combination of grass, restrained bitterness and creaminess. The aftertaste was long and rather pleasant for those who prefer it quite astringent.
However, even when you hit the elusive balance of time, temperature and leaf amount you get a representative but not a particularly complex Long Jing. Aside from its wet leaf aroma nothing really was that impressive to me.
On the other hand, this tea is already 9 months old and I am not much into green teas in general, so you may want to take my review with a sizable grain of salt.
