As a complete newb to tea 12 years ago, but instant explorer. I bought a tin of Republic of Tea (RoT) Sky Between the Branches Chinese Green http://www.republicoftea.com/sky-between-the-branches-green-full-leaf/p/V00605/
. I have to say, I was quite the sucker for their marketing at the time.
Following the brewing directions on the tin, calling for boiling water, yielded a bitter brew second to none ... it is amazing I did not toss the can in the trash and never try greens again.
But instead I called the customer service #. In hindsight, the woman was NOT trained in the brewing of green teas and stood by the directions on the label.
Still, I did not quit the greens, but did figure out how to brew them sans TeaChat. And obviously still love the greens.
The other most memorable one was a Darjeeling, from RoT. Again followed the directions, and again bitter to the nth degree. And again the customer service person towed the corporate line and said, "a good tea will be bitter ..."
Needless to say, I moved on from RoT ... and they are "my Teavana," both good and bad.
But wait ... they have a new sencha ... I think I will passssssss ...
