I'm gonna agree with Greg. I don't find any sweetening of the smoke but very cool and dry. Once I have it broken in I will try it without the filter to see just how much of a difference it makes. I would have liked it if it had come with more than one filter but no big deal. It does have a bowl coating. I have only ever had 2 other pipes with bowl coatings and weren't fond of them as they imparted a taste that I didn't care for for the first few smokes. I don't get any flavor from this coating though.
