The flavor is deep and rich, with an aroma which reminds me of a good pipe tobacco. Some bitterness, as I’d expect in any substantial yerba mate. This has stems included. Some mate drinkers claim that the stem has more theobromine than the leaf, and that consequently yerba ‘con palo’ (with stems) produces more euphoria in the drinker. I’ve not been drinking YM long enough to have an opinion about stems. I bought a kilo of this, and I’m glad I did. Really energizing, and in a good way.
