How is the flavor profile of the bilberry generally described in comparison to milder blueberries?

Answer

Stronger, richer, and more intense flavor with astringency

The flavor difference between the two berries is directly attributable to their pigment and compound concentrations. Bilberries are characterized by a flavor profile that is decidedly stronger, richer, and far more intense than that of most cultivated blueberries. They often exhibit a distinct tanginess coupled with a noticeable astringency. This astringency is amplified by the berry's higher concentration of anthocyanins. Because of this concentrated flavor intensity, a smaller quantity of bilberries can often achieve the desired flavor impact in culinary applications, such as jams or preserves, compared to the milder, sweeter profile typically offered by highbush blueberries.
