Gran Clos

Old-vine grenache and carignan on Priorat's black slate, with a flagship red aged in French oak and a white from garnacha blanca and macabeo.

The producer

Gran Clos farms 32 hectares of grenache, carignan, and white varieties in Priorat, the DOQ appellation in southern Catalonia where fractured black slate forces vines deep and returns wines of concentrated dark fruit and mineral weight. The estate began in 1995 when Josep Maria Fuentes chose to revive old grenache and carignan vineyards rather than replant them, keeping root systems that now exceed a century of age.

In 2002, British buyer John Hunt acquired the estate, renamed it from Celler Fuentes to Gran Clos, and brought in Josep Angel Mestre as winemaker. Mestre came with formal training in agricultural engineering, enology, and winemaking from France. Over the following two decades, the combination of old vines and technically grounded winemaking moved Gran Clos to the top position in a ten-year blind tasting of Priorat producers and onto Wine and Spirits magazine's Top 100 Winery list in 2020.

Known for

Finca El Puig, a red blend of old-vine grenache, syrah, and carignan aged 13 to 15 months in French oak.

Notable facts

The story

The Renaming

Josep Maria Fuentes had spent seven years nursing old grenache and carignan vines back into production when, in 2002, a British buyer named John Hunt walked in and bought the estate. Hunt renamed it. Celler Fuentes became Gran Clos, a name that meant great enclosure and said nothing about the family that had started the work. He brought in Josep Angel Mestre as winemaker, a man who had studied agricultural engineering, enology, and winemaking in France before returning to a family tradition rooted in Falset. Mestre applied a level of technical rigour the estate had not had before. Within less than two decades, Gran Clos had been named a Top 100 Winery by Wine and Spirits and had come first in a ten-year blind tasting of Priorat producers judged by critics, sommeliers, and international judges. The old grenache vineyards that Fuentes had chosen not to pull up were still there, producing fruit from roots that had been working the slate since before either man was involved.

At A Glance

The Producer

Gran Clos farms 32 hectares of grenache, carignan, and white varieties in Priorat, the DOQ appellation in southern Catalonia where volcanic slate soils and near-vertical terraces make viticulture genuinely difficult and the wines correspondingly concentrated. The estate began in 1995 when Josep Maria Fuentes chose to revive old grenache and carignan vineyards rather than replant them, keeping root systems that now push well past a century of age.

In 2002, British buyer John Hunt acquired the estate, renamed it from Celler Fuentes to Gran Clos, and brought in Josep Angel Mestre as winemaker. Mestre arrived with formal training in agricultural engineering, enology, and winemaking from France, skills not common in what was still a mostly regional producer landscape. The name Celler Fuentes became Gran Clos. Over the following two decades, the combination of old vines, technically grounded winemaking, and international ambition moved Gran Clos from a local address to a Priorat producer ranked top in a ten-year blind tasting judged by critics, sommeliers, and international judges, and named to Wine and Spirits magazine's Top 100 Winery list in 2020.

Place

Priorat sits inland from Tarragona, hemmed by the Serra del Montsant range. The DOQ classification, one of only two in Spain with that status, covers a tight cluster of villages in the Siurana river valley. What separates Priorat from the broader Montsant appellation surrounding it is primarily the llicorella: a fractured black slate and quartz soil that drains fast, forces vines deep, and returns wines with a mineral density and dark fruit weight that is hard to find elsewhere on the Iberian Peninsula.

The slate drains so aggressively that vines without old root systems cannot manage dry summers without irrigation. Old-vine grenache on llicorella solves this differently: roots mine meters into the fractured rock, finding moisture and minerals that younger plantings cannot reach. Low yields follow naturally, and the fruit that does form carries the kind of concentration and flavour depth that explains why Priorat commanded a DOQ designation.

Soil And Site

Gran Clos vineyards sit on llicorella, the signature Priorat soil formed from decomposed Silurian slate mixed with fragments of quartz. The black slate absorbs heat through the day and releases it overnight, extending ripening. Quartz fragments scatter light back onto the vine canopy. Water drains fast through the fractured layers, and vine roots must go deep to find it. For vines exceeding 100 years of age, those roots are deeply established in the rock, producing small clusters of intensely flavoured fruit with naturally low yields.

Story

Josep Maria Fuentes made a decision in 1995 that the old vineyards were worth keeping. Grenache and carignan, both of which can seem unfashionable beside international varieties, had survived decades in Priorat on llicorella. Fuentes chose not to pull them up.

Seven years later, John Hunt arrived with a different kind of ambition. He bought the estate, changed its name, and hired Mestre. Mestre's French training gave Gran Clos a winemaking approach grounded in agricultural engineering, enology, and winemaking that complemented the raw material Fuentes had preserved. The reorientation was not cosmetic. Gran Clos began entering its wines in international competitions and tastings, building a market presence beyond Catalonia. The old-vine foundation Fuentes had kept became the basis for a producer operating at a different level of expectation.

Vineyards And Cellar

The oldest vines on the estate are grenache, some exceeding a century. Old vines on llicorella produce smaller, more concentrated fruit than younger plantings: less juice per cluster, more skin-to-juice contact, more extraction of the mineral and dark-fruit character the slate contributes. Syrah is planted as a blending component rather than a stand-alone variety.

Finca El Puig, the flagship red, ages 13 to 15 months in French oak. Oak at this duration integrates into the wine rather than dominating it: the dark fruit, pepper, and balsamic notes that come from old-vine grenache on slate survive the ageing process and remain the primary character of the wine. Gran Clos Blanc ages on lees in French oak, a method that adds texture and a faint creaminess to the mid-palate without covering the mineral and herb notes that the garnacha blanca contributes.

Wines

Finca El Puig is the estate's primary red wine, a blend of 73% Garnacha, 17% Syrah, and 10% Cariñena aged 13 to 15 months in French oak. Across vintages it carries red and black fruit, balsamic, floral notes, and a peppery quality from the syrah and the slate. The 2013 tasted ripe and well-knit, with fresh red and black fruits, forest herb, and a fruity, well-balanced palate with fine tannin. The 2022 came across as younger and tighter: damson, dusty earth, blackberry, and pepper on the nose; peppery black fruit, warmth, and a clean bitter touch on the finish.

Gran Clos Blanc is the white wine, a blend of 76% Garnacha Blanca and 24% Macabeo, lees-aged in French oak. It pours luminous straw yellow with a golden rim and offers complex aromas of peach, quince, herbs, and balsamic with an underlying mineral thread.

The two wines make a coherent pair: the red built for medium-term ageing, the white more accessible in youth, both shaped by the same llicorella soils and the same philosophy of minimal intervention between vineyard and bottle.

In The Glass

Finca El Puig opens with dark fruit: blackberry, damson, and a dusty, earthy note that comes directly from old grenache on slate. Pepper from the syrah component rises alongside. In the mouth, the wine is full-bodied without being heavy, with a warmth that reflects both the grape and the Priorat climate. Acidity holds the wine in shape through the mid-palate, and the finish carries a clean, slightly bitter edge characteristic of carignan. Young vintages are tight and need time; older vintages develop a spiced, creamy depth that the initial fruit obscures.

Gran Clos Blanc reads differently: the garnacha blanca contributes stone fruit and a broad, mouth-filling texture. Lees ageing adds weight without removing freshness. The mineral and herb notes give the wine a savouriness that keeps it from reading as simply fruity. Acidity stays present through the finish, preventing the oak from feeling heavy.

A Bottle To Understand It

Start with Finca El Puig. It is 73% old-vine grenache grown on llicorella, blended with syrah and carignan, and aged 13 to 15 months in French oak: a direct expression of what Priorat slate does to grenache at vine age. The wine opens with dark fruit, pepper, and earth, builds to a warm, concentrated mid-palate, and finishes with a bitter edge from the carignan. It is not a light wine: the slate, the vine age, and the climate all point toward weight and flavour density. Give a young vintage three to five years, or seek out an older vintage to see what the wine becomes when the fruit opens and the oak fully integrates.

Anecdote

Josep Maria Fuentes had spent seven years nursing old grenache and carignan vines back into production when, in 2002, a British buyer named John Hunt walked in and bought the estate. Hunt renamed it. Celler Fuentes became Gran Clos, a name that meant great enclosure and said nothing about the family that had started the work. He brought in Josep Angel Mestre as winemaker, a man who had studied agricultural engineering, enology, and winemaking in France before returning to a family tradition rooted in Falset. Mestre applied a level of technical rigour the estate had not had before. Within less than two decades, Gran Clos had been named a Top 100 Winery by Wine and Spirits and had come first in a ten-year blind tasting of Priorat producers judged by critics, sommeliers, and international judges. The old grenache vineyards that Fuentes had chosen not to pull up were still there, producing fruit from roots that had been working the slate since before either man was involved.

Final Word

Gran Clos is a Priorat estate built on two decisions made thirty years apart: Fuentes keeping old vines in 1995 when replanting would have been easier, and Hunt committing to professional winemaking in 2002 when the estate could have remained regional. Finca El Puig is the product of both choices: old grenache and carignan on black slate, aged in French oak, with enough concentration to develop across a decade in the bottle.
