MazueloSpain's secret weapon for structure, tannin, and age-worthy Rioja blends

Mazuelo, known as Carignan in France, is a hidden gem in Spanish winemaking, particularly in Rioja where it plays a crucial supporting role. Originally from Aragón, this hardy grape thrives in hot, dry climates and was once the most widely planted red variety in the world. While it fell out of favor due to high yields producing dilute wines, old-vine Mazuelo from low-yielding vineyards tells a completely different story.

In Rioja, Mazuelo typically comprises 5-10% of traditional blends, adding backbone, color, and tannic structure to Tempranillo's elegance. Modern winemakers are rediscovering its potential, with some producing compelling single-varietal bottlings that showcase its intensity and aging capacity. Its thick skins provide deep color and tannins that soften beautifully over time, making it essential for wines meant to age gracefully for decades.

Mazuelo delivers bold, rustic character with intense dark fruit flavors of blackberry, black plum, and black cherry, often accompanied by notes of dried herbs, black pepper, licorice, and earthy minerality. The grape's high acidity and substantial tannins create a firm, structured mouthfeel that can be quite astringent in youth but mellows into velvety complexity with age.

On the palate, expect a full-bodied wine with gripping tannins and a long, persistent finish. Mazuelo pairs beautifully with hearty, robust dishes like lamb stew, grilled ribeye, braised short ribs, or aged Manchego cheese. Its structure and acidity cut through rich, fatty meats while complementing the savory depth of slow-cooked dishes. Give it time in the cellar or decant generously to unlock its full potential.
