The Penedés region began to commercialize its wines towards the end of the 1960s, and did so using wines that were before only used as a base for cava. New varieties were incorporated, such as Cabernet, Merlot and Chardonnay. Since then, Penedés whites have gained international attention.
Not only the Penedés D.O. uses Chardonnay grapes; the Costers del Segre D.O. does so as well, and creates with them aromatic wines with great results after a short aging. Costers also uses Xarel.lo in addition to Chardonnay to produce its whites.
A autoctonous Catalan grape called Picapoll is the main ingredient in the DO Pla de Bages wines, which are fresh and floral whites.
The White Garnacha is another grape variety very popular in Catalan wines, making appearances in the DOs Alella, Costers del Segre, Tarragona and Terra Alta. This grape yields wines with a high alcohol level.
Very aromatic wines are often made with a Greek grape variety called Subirant Parent.
Xarel.lo, Macabeo and Parellada grapes are the most common varieties for producing cava, an aromatic wine akin to champagne and found in the DOs Alella, Costers del Segre, Penedés and Tarragona. Parellada Blanca is the highest quality cava grape.
