Kéknyelű is a Hungarian grape variety grown only in Badacsony and the Balaton highlands. Before the phylloxera blight, it was popular and expensive. The wine is pale in color and has a restrained aroma, mainly reminiscent of white-fleshed fruits, citrus, sometimes flowers and green spices.
In 2022, the product won the Balaton Upland National Park Product Trademark again.
