A sipdown! (M: 3 Y: 19)
This was my office tea and I have to say it was pretty decent, considering price / quality = wake me up effect ratio.
It’s quite common here to add a lemon juice to the cup of plain black tea; so this combines both and quite well. The result is not sour at all, the base tea is strong and very robust, and, if steeped properly, not bitter.
Of course, I did several 15+ minutes long steeps — and that I can’t recommend, but 3 minutes seems just fine. Sadly, they just say the tea is from various origins, but they don’t tell them. But in my opinion, it is not just a Ceylon tea.
