I feel the smoke flavor is very "clean" and it has a pleasant smell. As I say this, I should disclose that I prefer the smoke flavor I get from my charcoal burners, only because the charcoal seems to add additional flavor. Having said that I must admit I prefer to smoke/cook my butts in the Bradley. The smoke flavor from the Bradley is more consistent. Bradley states it is because the bisquettes will only burn for 20 minutes, but I feel it is because the bisquettes burn at a consistent rate of around 550°F.
I know people who don't like smoked foods. Have you smoked using other methods, or tasted smoked foods prepared by others, to compare it to the smoke taste from the Bradley? Smoke taste is a personal preference. Is your drip tray clean? Buildup on the drip tray can cause an "off" flavor, but more like a burnt flavor.
