Xarel·lo is a Spanish grape variety best known for its use in sparkling Cava, where it is used along with Macabeo and Parellada. It is a high-quality grape that provides power, body, and structure in Cava wines. It is the most planted variety in DO Penedès.

Apart from sparkling wines, the grape is used for dry white wines, both varietals and blends. Wines made from Xarel·lo are medium-bodied and aromatic, with good acidity and alcohol content. The aromas are reminiscent of citrus and stone fruit, and the wines will typically have herbal and mineral character. 

Garnatxa Blanca or Grenache Blanc is a white wine grape variety that is a mutation of the red Garnacha grape. It is predominantly grown in Spain and France, but it is also found in other wine regions around the world. Garnatxa Blanca is known for producing wines that are full-bodied and aromatic with a rich texture and relatively high alcohol content.

In terms of flavor profile, Garnatxa Blanca wines often exhibit notes of green apple, pear, citrus (such as lemon and lime), and white flowers. They can also have hints of stone fruits like peach and apricot, along with a distinctive minerality. When aged or fermented in oak, the wines can develop additional flavors of vanilla, almond, and spices. 

Sumoll is a rare red grape native to Catalonia. It is an old, late-ripening variety that is somewhat finicky to cultivate and vinify. Although it declined in popularity throughout the 20th century, it is still important in Penedès DO, where it is used both in varietals and blends, and for still and sparkling wines.

Sumoll will usually result in full-bodied, somewhat rustic red wines. The aroma is fruity, usually with some herbal notes and a mineral character. Sumoll is excellent at retaining freshness, creating lively and bright wines with vibrant acidity. It was proven that Sumoll is identical to Vijariego Nego, a variety grown on the Canary Islands where it is used in several regional appellations.
