According to TeaGshwender, this tea was grown in the Steinthal estate which is one of the oldest gardens in Darjeeling. When Darjeeling teas are sold, they are graded by size and quality. This particular tea is marked as FTGFOP1 (Fine Tippy Golden Flowery Orange Pekoe 1). The dry leaves were a mottled mix of greens and browns. I made this tea in my Breville One-Touch Tea Maker with 212 degree water for two minutes. The liquor was a pale gold.
This tea was surprisingly herbaceous, almost reminding me of Tulsi. It was very astringent but not in an unpleasant way. The muscatel flavor was very light but there was an added maltiness that I have never experienced in a Darjeeling. This is the third Darjeeling that I have tried from TeaGshwendner and they have all been very different from each other. I would definitely recommend this tea.
I have tried only one tea from Steinthal estate, and it was disappointing at first, but then I later tried pairing it with spicy, salty foods and I found that its flavor really made it take on a new light, and I loved it.
Although the tea I tried was out of season and a lower-grade, broken-leaf tea, it definitely shares the sort of malty depth that you describe in this review.
It's also good and useful to hear that the Darjeelings you've tried from TeaGschwender have been distinctive in their qualities–this is always a good thing and would make me more likely to order from them.
The Darjeeling I have been drinking lately has a similar profile.
