Costers del Siurana (Clos de l'Obac)

Costers del Siurana was established in 1987 by journalist Carles Pastrana and oenologist Mariona Jarque in Gratallops, in the heart of Priorat. The region had suffered economic collapse, and the winery became one of five pioneering estates, collectively known as the Gang of Five, that rebuilt Priorat's reputation as a serious fine wine region. Their first harvest came in 1989, with the wines bottled in 1991. By 1993, Clos de l'Obac had been named one of the World Wine Guide's 150 best wines, confirming Priorat's rapid rise on the international stage.

• Founded 1987 in Gratallops, Priorat, Catalonia
• First harvest 1989; first bottling 1991
• Named in World Wine Guide's top 150 wines in 1993
• Part of the Gang of Five that pioneered modern Priorat

The estate's vineyards span 27-35 hectares at elevations ranging from 250 to 550 meters above sea level. The soils are dominated by llicorella, the dark metamorphic slate with quartz that defines Priorat's most distinctive terroir. This fractured slate forces vine roots to penetrate deep into the rock in search of water and nutrients, concentrating flavors in the grapes. The climate is Mediterranean, moderated by altitude and the Montsant mountain barrier, which tempers summer heat and preserves acidity. The estate also includes the Mas d'En Bruno property, featuring a 13th-century villa.

Costers del Siurana produces four principal wines. Clos de l'Obac is the flagship red blend, while Miserere is a second red bottling. Kyrie is the estate's white wine, and Dolç de l'Obac is a sweet wine. A defining feature of the winery's approach is the fixed coupage system, where the same grape percentages are used each vintage. This deliberate consistency allows vintage conditions to express themselves clearly through climate variation rather than blending adjustments. Red wines undergo extended oak aging of 12-15 months. The grape portfolio is broad, encompassing Grenache, Carignan, Cabernet Sauvignon, Merlot, Syrah, and Tempranillo for reds, alongside White Grenache, Macabeu, Xarel·lo, and Muscat d'Alexandria for whites.

• Four wines produced: Clos de l'Obac, Miserere, Kyrie, and Dolç de l'Obac
• Fixed coupage system used across all vintages to showcase climate variation
• Red wines aged in oak for 12-15 months
• Production of approximately 50,000-70,000 bottles per year

The estate maintains a commitment to sustainable viticulture and winery operations. Costers del Siurana has installed solar power and implemented water conservation measures across the property. These practices reflect a broader stewardship philosophy toward the estate's unique llicorella landscape and the wider Priorat environment.
