So, right off the bat, I want to say that this is a smokey mate. Not, like, say Rosemonte Especial, but if you are concerned about the health effects of drinking smoked mate (I think in small amounts it is probably fine), you may want to avoid this.
However, I think this is overall, a very smooth mate, despite the smokey notes. It isn't bitter at all and doesn't offend the palate. Even new mate drinkers will love this one. It is a great introduction to the world of mate. My one complaint is it can be hard to get ahold of due to the limited production, so get some as soon as you know it is available!
Note from GoYerbaMate: This yerba is not smoked,( it is organic ), it is stored for two years in small wooded stalls to created that flavor.
