The Producer
Casa Mariol makes single-variety wines and vermouths from the inland heat of Terra Alta, a DO tucked into southern Catalonia where most producers have historically sold Garnacha in bulk rather than bottling it themselves. The Vaquer siblings changed that calculus at their family estate in Batea. Josep Maria handles the winemaking, Miquel Àngel and Marta work alongside him, and the three of them have built a range that is immediately recognisable on a shelf because of its design: German art director Mirko Borsche created the bottle aesthetic, giving Casa Mariol a visual clarity that is rare in this part of Spain.
The estate's Garnatxa Blanca and Garnatxa Negra carry organic certification. Every wine and vermouth in the portfolio has been vegan certified since 2019, which means no fining agents of animal origin at any stage of production. An in-house laboratory handles traceability and quality analysis across the range.
Place
Terra Alta sits at the southern edge of Catalonia, far enough inland that the coast's moderating influence fades and the growing season turns hot and dry. Batea is near the centre of the DO, at altitude, on soils that are predominantly calcareous. Two winds cross the vineyards: the cierzo, a dry northerly that arrives from the Ebro valley and keeps humidity low, and the garbí, a moist southeasterly that tempers the heat in warmer periods. Together they push vines toward thick skins and concentrated fruit rather than broad, flabby ripeness.
Calcareous soils drain quickly and limit vine vigour, which tends to reduce yields and push intensity into the grape rather than volume. For Samsó (Carignan), the same combination produces dark fruit and firm acidity. Terra Alta wines carry DO status on the label, and Garnacha in its white and black expressions is the appellation's signature grape.
Soil And Site
The vineyards around Batea sit on predominantly calcareous soils with good drainage. The two prevailing winds, cierzo from the north and garbí from the southeast, regulate temperature swings across the growing season and keep disease pressure low, which reduces the need for intervention in the vineyard. Casa Mariol farms 50 hectares of estate vines and draws additional fruit from small farms in the surrounding area. The estate describes its farming across the range as sustainable and eco-friendly; the Garnatxa Blanca and Garnatxa Negra parcels hold certified organic status.
Story
Josep Maria Bes and Josefina Aguiló founded the winery in 1945. In 1971, their children Josep Vaquer and Emília Llop took it over. During the 1980s, when most of Terra Alta was selling Garnacha to bulk buyers, this second generation chose a different direction: they planted Syrah and Cabernet Sauvignon, international varieties that were then barely present in the DO, and began bottling under their own label. That was an unusual act of ambition in a region where commodity production was the economic norm.
The third generation, Josep Maria, Miquel Àngel and Marta Vaquer, inherited that bottling practice and extended it. They turned the estate's focus back toward native varieties, developing the certified organic Garnatxa range and commissioning Mirko Borsche to build the house's visual language. They also expanded the business into vermouths, launching a black vermouth first and then reformulating a white vermouth that went on release on 1 January 2015. The portfolio now runs across both categories, and the design language ties them together.
Vineyards And Cellar
Casa Mariol farms its 50 estate hectares under sustainable principles across the range, with the Garnatxa Blanca and Garnatxa Negra parcels certified organic. Calcareous soils and low rainfall reduce the need for chemical inputs. The two winds limit humidity, which keeps fungal pressure down in the vineyard.
In the cellar, the Samsó Crianza receives ageing in American oak before a period of bottle rest prior to release. The oak contact gives the wine toasted wood character and softens the tannins that Carignan naturally carries. The Garnatxa Blanca and Garnatxa Negra wines are made to organic standards with no animal-derived fining agents. The White Vermouth is produced from a Macabeo base, flavoured with botanicals native to Terra Alta, and released without ageing to preserve the fresh aromatic character of the herbs.
Wines
The range divides into wines and vermouths, both built around single varieties or single-botanical profiles.
The Garnatxa Blanca is a dry white wine from certified organic white Garnacha. White Garnacha in Terra Alta tends toward a broad, full-bodied palate with stone fruit, low-to-moderate acidity, and good weight. The organic farming and the calcareous soils keep the fruit defined without adding richness beyond what the grape and site produce.
The Garnatxa Negra is the red counterpart, made from certified organic Grenache Noir. Grenache from inland, calcareous sites in this part of Catalonia typically gives ripe red fruit, warm spice, and a soft tannin frame, with the cierzo wind helping to maintain freshness through the growing season.
The Samsó Crianza is made from Samsó, the local name for Carignan, aged in American oak with subsequent bottle rest before release. It carries dark fruit (blackberry, plum), toasted oak, soft tannins, and ripe acidity. Carignan grown on calcareous soils with low yields produces more concentrated fruit than the grape's reputation as a bulk variety might suggest.
The White Vermouth (Vermut Blanc) is made from a Macabeo base and flavoured with botanicals sourced from Terra Alta: rosemary, thyme, citrus peel and vanilla. It is lemon-yellow in the glass, sweet at over 130 grams per litre of residual sugar, and unoaked. The black vermouth preceded it in the range.
In The Glass
Across the wine range, Terra Alta's heat and calcareous soils show most clearly in the body: these are not lean, cool-climate wines. The Garnatxa Blanca opens with stone fruit, pear and a faint floral lift; the mouth is full and broad, with moderate acidity keeping the weight in check. The Garnatxa Negra has ripe red fruit on the nose, warm spice in the mid-palate, and a soft finish without hard edges.
The Samsó Crianza moves into darker territory: blackberry and plum on the nose, followed by the toasted, slightly smoky character of American oak, and a finish that stays ripe and warm. The tannins are present but rounded by the ageing and bottle rest. Acidity holds the fruit together without sharpness.
The White Vermouth is a different register entirely: herbal and sweet on the nose, with rosemary and citrus coming through clearly, the Macabeo base giving body, and the high residual sugar making it a sipping vermouth rather than a dry aperitif.
A Bottle To Understand It
Start with the Samsó Crianza. Samsó is the Catalan name for Carignan, a grape that most drinkers know only from cheap southern French blends. In Terra Alta, farmed on calcareous soils and aged in American oak before release, it produces something more considered: dark fruit, toasted wood, soft tannins, and the ripe acidity that the cierzo wind preserves through the growing season. The bottle gives a direct read on what Terra Alta's conditions do to a red grape with genuine character, and it shows what Casa Mariol does in the cellar with oak and time. It is the wine in the range with the clearest structural arc from vineyard to glass.
Anecdote
In the 1980s, when Terra Alta was still largely a bulk-wine region selling Garnacha by the tanker load to négociants who would blend it away, Josep Vaquer and Emília Llop drove up to their parcels in Batea and planted Syrah and Cabernet Sauvignon. Neither grape had any real presence in the DO at the time. The neighbours were not planting international varieties; they were managing Garnacha for volume. The Vaquers planted anyway, bottled the wine under their own label, and sold it as a single-variety estate wine from a region the market had not yet decided to take seriously. Their children inherited both the vineyards and the habit of doing things differently.
Final Word
Casa Mariol is the kind of family estate that rewards attention. Three generations have farmed the same calcareous ground in Batea, and each has left a mark on what comes out of the cellar. The Garnatxa wines carry organic certification and the grape's natural weight. The Samsó Crianza shows what Carignan can do with a little time in oak. The vermouths, flavoured with local botanicals, are an extension of the same place-first logic. Mirko Borsche's design makes the bottles recognisable; what is inside them earns the look.
