The Llicorella — Priorat’s Defining Soil
There are soils that define a wine region the way geography defines a country. Priorat’s llicorella — a local name for the black and reddish slate and quartz schist that dominates the hillsides — is one of the most distinctive terroirs on earth. Stand in a Priorat vineyard and the ground cracks and shifts beneath your feet like broken china. It is poor, ancient, friable rock that reflects heat, stores warmth, and drains water so efficiently that vines have no choice but to drive their roots metres deep in search of moisture.
This struggle is the source of Priorat’s power. Low-yielding, deeply-rooted old vines produce tiny quantities of extraordinarily concentrated fruit. The black slate imparts a mineral quality — a smoky, graphite, iron-tinged precision — that no amount of winemaking can manufacture. You either have llicorella beneath your vines or you do not. This is why Priorat’s DOCa designation (one of only two in Spain, along with Rioja) is so fiercely protected, and why the wines command such serious prices.
The landscape is equally dramatic. Priorat sits in a natural amphitheatre of steep terraced hillsides, carved out over centuries by Carthusian monks who established the priory (prieuré) that gave the region its name. The Sierra de Montsant surrounds the valley. Viticulture here is not easy labour: there is almost no possibility of mechanisation on the steeper sites. Every harvest is essentially hand-crafted.
The Rebirth — Álvaro Palacios, René Barbier, and the 1990s Revolution
By the late 1980s, Priorat had all but disappeared from the wine map. The region’s reputation, once considerable in the 19th century, had collapsed. Young winemakers had left for the cities. The old vines — some Garnacha plantings over 80 years old — remained largely forgotten, tended by elderly farmers with no commercial future in sight.
Then came René Barbier (Clos Mogador), Álvaro Palacios (L’Ermita, Finca Dofí), Carlos Pastrana (Clos de l’Obac), Dafne Glorian (Clos Erasmus), and José Luis Pérez (Clos Martinet). Five producers, often called the Quintet or the Clos Group, who arrived in the late 1980s and recognised what everyone else had missed: that these old Garnacha and Cariñena vines on black slate were producing fruit of extraordinary quality, and that the region was ready for a renaissance.
L’Ermita — Álvaro Palacios’s grand cru, produced from a single small plot of very old Garnacha vines — became one of Spain’s most sought-after and expensive wines almost immediately. Complex, mineral, impossibly concentrated yet elegant, it demonstrated that Priorat could compete with Burgundy’s greatest Pinot Noirs in terms of price and cultural significance. The wine’s name means “the hermitage” — an apt reference to the monastic origins of the landscape.
The village system is Priorat’s next chapter. Gratallops , El Lloar , Porrera , and Torroja del Priorat are all developing their own identities under the Vi de Vila designation — a classification that rewards the distinctive character of individual villages, much as Burgundy’s village appellations do. Porrera, with its higher altitude and cooler nights, produces wines of notable freshness for the region. Gratallops, where the Quintet first gathered, remains the symbolic heart.
Old Vines, Great Wines — The Ungrafted Heritage
Priorat escaped phylloxera, the vine louse that swept through European vineyards in the late 19th century and forced almost every producer to graft their vines onto American rootstock. The isolation of the mountainous terrain — too steep, too remote — combined with the sandy nature of some of the slate soils provided natural protection. As a result, Priorat retains some of the oldest own-rooted (ungrafted) vines in the world, particularly old-vine Garnacha that dates back a century or more.
Ungrafted vines are thought to produce wines of exceptional complexity and subtlety — there is an unmediated directness between the vine, the soil, and the fruit. Whether or not this is wholly provable scientifically, the wines from Priorat’s oldest parcels do have an unmistakable density and depth that sets them apart from even the best grafted old vines.
The second grape — Cariñena (Carignan in French) — deserves more credit than it often receives. In lesser hands and lesser terroirs, Carignan produces harsh, tannic, rustic wine. But Priorat’s old-vine Cariñena, planted in the most extreme sites, produces extraordinary complexity — savoury, herbal, with a spicy precision that balances Garnacha’s richness perfectly. The greatest Priorat wines are almost always blends of the two.
For those whose budgets stop short of L’Ermita, there is enormous quality at mid-range prices from producers such as Scala Dei , Mas Doix , and Cims de Porrera . And just outside the DOCa boundary, the neighbouring Montsant DO produces wines from similar soils and grapes at a fraction of the price — the intelligent Priorat lover’s shortcut.
