Xarello or "Xarel-lo" is indigenous to Spain and particularly popular in Catalonia northeastern Spain, also called Pansa Blanca or Cartoixa there.
It's a light-skinned grape, traditionally blended with Parellada and Maccabeu for the production of Cava. It is also widely used for the production of fine and characterful dry still white wine bringing excellent acidity and body structure. Young wines made of Xarello tend to be fresh with fruity and floral aromas. Xarello is grown in a number of wine appellations including Penedès and Alella, which is the smallest and oldest Spanish wine appellation.
