So it turns out I have been under steeping mate based teas. I went 3 minutes previously.
That being said, I think MateVane is a killer app for blended sweetish teas mate.
Nice rich dark tincture topped off by a visible oil greeted me after pouring my cuppa.
The flavor notes of cocoa and a nutty note were predominant, and almost had a lactose sweetness to it. (sorta like a Milk Stout beer)
Over all delightful. I could drink a lot of this.
