Bodegas Argüeso produces sherries in Jerez, the storied region of Andalucía where Palomino grapes transform into the world's most complex fortified wines. The winery's Castillo de Argüeso, a Palomino expression, has earned recognition from Falstaff, Decanter, Wine Spectator, and Wine Enthusiast. The 1822 Manzanilla Pasada Soleras de Viruta del casco de San León—another Palomino-based wine—demonstrates the house's command of the solera system, that centuries-old method of fractional blending that builds depth and nuance across generations of barrels. Manzanilla, the driest and most delicate category of sherry, thrives in Sanlúcar de Barrameda's maritime climate; the pasada designation signals extended aging that adds richness and amber hue. Both wines reflect the precision required to craft sherry: meticulous grape selection, careful fortification, and patient maturation under flor—the wild yeast that protects and seasons the wine.
