It has all to do with the flowers which the bees are visiting. You may notice, in the stores stocking honey, that there are different shades of color to honey. Each will taste differently in concert with its color and all dependent on the busy bees efforts... Most honey here in the western U.S., at least, comes from clover, since that is the most common flower available. It produces an acceptable, light colored and mild tasting honey. One other determining quality is the inclusion of some of the "beeswax" used by the bees to cover and store the honey. This is usually removed during a heating and centrifuge process, however, honey eaten directly from the "comb" has an entirely different flavor from that packaged commercially...
