Varietal honey is honey in which the nectar comes primarily from one type of flowering plant. Not exclusively—bees go where they want—but predominantly.For example, when black locust trees are in bloom and the bees are actively working those blossoms, much of the nectar they collect may come from black locust. The resulting honey takes on the distinctive color, aroma and flavor associated with that nectar source. That's Black Locust honey.That's also why different honey varietals can look and taste remarkably different—even when they're produced by the same bees in the same part of Iowa.
