Hi! Got into the hobby about a month ago and have been trying some different tobaccos. I currently have 3 pipes in rotation (eyeing a ton more) and have noticed a bit of an odd flavor now and then with certain blends. I'm a slow smoker by the way... usually about an hour per bowl. This flavor is almost a steamy metallic taste that occurs when I draw a light smoke or when the tobacco is about to extinguish. Its not noticable though when I relight or get the pipe going for some strong puffs. I'm currently trying 6 different blends and the two this occurs most with are blended with light and dark cavendish. For some reason I can't taste the nutty tobacco flavor in those... Any thoughts? Thanks!
