In reality, the different colors of cava and champagne have the same basis as all other types of wine. The different white and red grape varieties also determine the tonality of sparkling wines. In the case of rosé wine, the color comes from the red grapes.
The traditional champagne is made in France with Chardonnay (white grape), leaving the Pinot Noir and Pinot Meunier (red grapes) for the production of rosé champagne. Cavas usually use Xarello, Macabeo and Parellada (white grapes) and Garnacha Tinta or Trepat for rosé, although there are also cava cellars that use French Pinot Noir.
