Pérez Barquero G1 Brut Nature represents an innovation in the world of Spanish sparkling wine, combining traditional techniques with advanced research. In collaboration with the University of Córdoba, Bodegas Pérez Barquero has developed this sparkling wine using an indigenous yeast from the Montilla-Moriles region, specifically isolated from Bodegas Gracia in the 1980s. This sparkling wine is made from Pedro Ximénez grapes from the best albariza vineyards, using old generous wines in the expedition liqueur, which provides a unique identity rooted in tradition. On the nose, aromas of ripe apple, white fruit, citrus, and pastry notes with a salty touch can be perceived. On the palate, it is dry, fresh, with fine, persistent bubbles, and a long finish with mineral and salty notes. Ideal for pairing with oysters, sushi, and umami dishes, though it is also excellent on its own.
