Drinking this tea today, I noticed some mild sour fermentation note and the flavours to be a bit muted overall. There is a touch more sweetness in the aftertaste, of the tree sap kind. Other than that, the experience matches my earlier encounters of it – with strong mineral, herbal bitterness in the center of the stage.

Ah, I still have a sample of this you sent. Will have to try it soon.
