I am not drinking this tea fast apparently.
I have used another 3 grams (7 are remaining) and brewed in 400 ml mug.
It turned out delicious, nice base and the citrusy notes! Wow! Smooth, enjoyable, Earl Grey, without any flaws, any astringency or some artifical notes.
If I ever travel over there, I will bring box to my father who loves Earl Greys!
