No, blue raspberries are not real. There are no actual blue raspberries in existence, but there is actually fruit behind the bright blue color. Known formally as" Rubus leucodermis", but more commonly as White Bark Raspberry, this fruit used in blue raspberry flavor is not exactly a raspberry. This berry has a texture akin to a blackberry and a tarter flavor. The actual berry is a reddish purple color at first, turning a deep bluish purple when ripe. But white bark raspberries are NOT blue. It's the food coloring we can thank for the blue part of blue raspberry. The white bark raspberry just happened to be the lucky fruit that was paired alongside the vivid blue dye we've grown to love.
