Where does Camphor flavor in Puerh tea come from?

„Then there is the more nuanced problem of what to do with the samples. It’s quite easy to say that sampling widely will give you experience in tea drinking. In practice, however, that’s not so simple. Of course, trying all kinds of teas will most certainly give you experience. However, it is experience on a relatively shallow level. Certain kinds of teas, such as really bad or really good teas, will probably manifest themselves quite readily. Others, however, are not so obvious. It is actually easier to try teas if you, say, cup them, but then it becomes work and the process is not very enjoyable. This is, ultimately, a hobby, and not a job (for me anyway) so taking the fun away like that is basically missing the point.“
