Rózsakő is other unique variety which is strongly linked to the Badacsony area. It is a crossing made from the Kéknyelű and Budai varieties. It was specifically developed in order to pollenize the Kéknyelű variety. Since Kéknyelű is one of the very rare varieties which has flowers that do not produce pollen, it must be planted next to another variety which can pollinate it. These days, the variety of choice for that noble job is Rózsakő. This wine has charming floral aromas, next to a moderate minerality—which is the trademark of the region—and flavors of melon and white peach.
