Kéknyelű is a white grape variety native to Hungary, primarily found in the Badacsony wine region. It is known for its unique blue stems, which give the grape its name, meaning "blue stem" in Hungarian. The grapes produce wines that are typically dry, with a fresh and fruity character, often featuring notes of green apple and citrus. This variety is appreciated for its ability to reflect the terroir, showcasing the mineral qualities of the volcanic soils in which it grows. Kéknyelű wines are often enjoyed young but can also develop complexity with age, making them a sought-after choice among wine enthusiasts.
