Stick your nose in a freshly opened box of band-aids and you'll get a blast of phenols. A common source for this flavor is often wild yeast or residual sanitizers in the beer equipment. Oversparging of your grains or over crushing of grains can lead to increased phenol levels (in the form of polyphenols, i.e. tannins).

However, many belgian yeast strains and several Weizen/Weissbier yeasts are selected specifically for those clove and banana like phenols relavent to the wheat beer style.
