I also ordered from DTH several packages of teas, and one green (bi lo chun) is most probably from last year, practically no higher fragrances. when I was ordering it the harwest year was stated as 2011. I am quite dissapointed. I dont understand why they risk the trust of their customers.
In my opinion, for Taiwan High Mountain Oolong the exact date of harvest is irrelevant because there are only 2 pickings per year, and no multiple flushes like dragonwell or darjeeling.
If I were buying online, I would definitely want to talk to the person(s) that run the store(s) in consideration. This kind of service is something we emphasize and a philosophy that we've adapted from game changers like Zappos. Through all the descriptions, I still feel tea is a product that people are more likely to buy if they can touch, see, smell, and feel it. You're never going to be able to do that online, but at talking to an honest seller is one step closer.
