The black and purple slate slabs that emerge among the rows of Clos Mogador have a precise name: llicorella. This schist rock, poor in nutrients and difficult to work with, forces the roots of the vines to dig deep to find water and minerals, producing concentrated grapes with a complexity that is immediately felt in the glass. We are in Gratallops, one of the smallest villages in the Qualified Designation of Origin Priorat, in southern Catalonia, about an hour and a half drive from Barcelona.
Clos Mogador is a family winery founded by René Barbier, one of the pioneers who in the 1980s helped bring Priorat back to international attention after decades of agricultural abandonment. Along with other local producers, Barbier was among the first to believe in the potential of these ancient terraces, some of which date back to the medieval period, when the Carthusian monks of the 12th century began the systematic cultivation of the vine in this rugged area. The winery primarily produces blends of Garnacha and Cariñena, two native grape varieties that express characteristics in this terroir that are difficult to replicate elsewhere.
The terroir of llicorella: what makes this soil unique
Walking among the vineyards of Clos Mogador means physically understanding why Priorat is so different from other Spanish wine regions. The terraces carved into the steep slope are narrow, often just wide enough to host a single row of vines, and the soil underfoot is crumbly, composed almost entirely of slate shards that reflect solar heat during the day and release it at night. This thermal excursion promotes the slow ripening of the grapes, preserving acidity and aromas even in the hottest years.
The oldest vines on the property are decades old and produce reduced quantities of grapes per vine. This natural low yield, imposed more by the harshness of the soil than by production choices, results in wines with significant tannic structure and a saline minerality that almost resembles certain wines from the southern Rhône. The Garnacha in this context loses its tendency towards excessive softness and gains tension and length on the palate.
The tasting: what to expect in the glass
The flagship wine of the winery bears the same name as the property, Clos Mogador, and is a blend of Garnacha and Cariñena with small additions of other grape varieties. On the nose, there are notes of ripe dark fruit, Mediterranean spices like thyme and rosemary, and a mineral iron background that directly recalls the slate soil. On the palate, the structure is firm, with tannins present but not aggressive, and a long and savory finish.
During the tasting sessions at the winery, it is possible to compare different vintages and understand how the climate influences the wine profile from year to year. The winery guides explain the differences between the plots and the specific role of each grape variety in the final blend. It is an educational tasting in the most concrete sense of the term, not just a simple sequence of tastings.
The visit: tour in the winery and among the vineyards
Clos Mogador receives visitors by mandatory reservation, and it is advisable to contact the winery at least a few days in advance, especially in the spring and autumn months which represent the period of greatest influx. The tour typically includes a walk among the terraces to closely observe the llicorella and the old vine stocks, followed by a visit to the winery where winemaking and aging take place.
The winery is located outside the center of Gratallops and the access roads are narrow and winding, characteristic of the entire Priorat area. It is preferable to reach the property by car, paying attention to the local signage. Those coming from Barcelona can take the AP-7 highway to Tarragona and then follow the signs to the Priorat region through scenic provincial roads. Avoid scheduling the visit during the central hours of July and August, when the heat can make the walk among the vineyards less enjoyable.
Why the trip to Gratallops is worth it
The Priorat as a whole is a region that requires some logistical effort to visit, but Clos Mogador offers a direct access point to an authentic local wine history. The family-run nature of the winery means that the experience remains personal, away from the mass wine tourism industry. You can concretely perceive the physical work that it takes to cultivate vines on these steep slopes.
Gratallops itself deserves a stop: the village has few inhabitants but retains well-preserved Catalan rural architecture. Pairing the visit to Clos Mogador with lunch in one of the small restaurants in the village, where local wines are often offered by the glass at reasonable prices, completes the experience in a way that is consistent with the authentic character of this corner of Catalonia.
