What grape varietals make up Spanish Cava?

The 3 main grapes that are in Spain’s famous sparkling wine are Macabeo, Xarel-lo and Parelleda. But in some instances, Chardonnay is now being included in some blends. A stark difference from true French Champagne which uses Chardonnay, Pinot Noir and Pinot Meunier exclusively. Cheers!
