B. Ull de Llebre
While Ull de Llebre (or “eye of the hare” in Catalan) is a Spanish grape grown in the Penedès, it is not a part of the seven grapes legally allowed to make cava. (It is, however, the local name for tempranillo). While chardonnay often adds finesse to cavas, the varieties macabeo, parellada, and xarel-lo are the most important. Macabeo is fruity and aromatic with good acidity. Parellada is the most delicate of these Spanish grapes and are often grown in higher, cooler vineyards. And you can thank xarel-lo for giving cava most of its personality by contributing good acidity and a generous, round body.
