A couple of years ago I knew nothing about puerh and my first trials of it were definitely not appealing. It was the cooked variety, but I realized that, in a weaker version, I'd been served it from time to time in Chinese restaurants.
Through acquaintance with several members of this newsgroup, I was introduced to better quality puerh, particularly the "green" puerh. which I find far more intriguing and rewarding.
I'm in. I've bought a yixing pot specifically for puerh, and have several varieties at hand. For me, a good green puerh (and both young and old can be good) is a real pleasure.
Yes, it can be an acquired taste, but if you have the good stuff, it's not a hard taste to acquire. For me, it's still not a tea I reach for on a daily basis, but it's often "just the thing."
