The name of this crossing of Silvaner and Muskateller derives from its breeder, Peter Morio, and its characteristically strong, rich bouquet that is reminiscent of Muscat grapes.
It adds a spicy touch to a blended wine. During the past twenty years, as the popularity of rather sweet, flowery wines has declined, the vineyard area covered by Morio-Muskat grapes has dropped by fifty percent. Nevertheless, it is still, almost exclusively, planted in Rheinhessen and the Pfalz. Meanwhile, it accounts for 0.4% of Germany's total vineyard area.
