While the notes of this tea are already accurate, I’d like to weigh in as I have drank this 3x at work in the morning.
The term bitter and chocolate does apply, but not in the sense of a bittersweet dark chocolate. This is more like the astringency of an Assam tea but a chocolate taste you would get from some leftover chocolate powder used in a mixture that happened to be on your fingertips. Not that strong, quite dry, but noticeable. I prefer my golden needle dianhong to this due to the bitterness that makes it hard to enjoy fruits right away in the morning.
