Speaking of Dayi, where exactly do they fall on the sliding scale of quality (qualitea?
Ok I'll stop)? My knowlege of branding could use improvement. Is there a big page that'll give me the skinny on the who's who in the tea world? So far I've really only stuck to one vendor.
I'd say that they are one of the best of the big factories, however, many people will prefer smaller production of "tea masters" or vendors who press their own "selected" stuff.
I myself tend to like Dayi teas in general as they are thoroughly solid and well blended. Unfortunately, some of their classical recipes (7542, 8582) went to hell recently and are not worth pursuing (imo) and most of their young stuff (possibly except Spring of menghai, which is quite good and cheap), they are greatly hyped - you pay a lot for the investment value, etc., not always just for the drinking pleasure.
Similarly, their +-2000 teas are often too expensive (although generally quite good).
I.e., if you can find a reasonably priced Dayi tea, it is likely fake, but if it is not, then go for it
This all may not sound overly positive, but I do feel quite good about the tea that Dayi makes actually. Surely better than about, e.g., Xiaguan.
