Why it matters
The producer
Alta Alella sits ten kilometres from Barcelona inside the Serralada de Marina Natural Park, which makes it one of the few serious wine estates in Europe that a city dweller could reach before lunch. The founding is not incidental to the wine: enologist Josep Maria Pujol-Busquets and his wife Cristina Guillén took over the Can Genís estate, farmed organically from the start, and in 2006 removed added sulfites from every wine they made, still and sparkling alike. Their daughter Mireia Pujol-Busquets now leads the estate.
The numbers tell a particular kind of story. The estate farms 68 hectares across three properties: Can Genís above the sea, 15 hectares in the neighbouring village of Tiana, and additional parcels in Vall de Rials on the far side of the appellation. From that land the cellar produces around 50 different wines each year through micro-vinification, separating parcels, vessels, and fermentation methods to keep each batch separate. Two-thirds of production is Cava; one-third is still wine under the DO Alella appellation.
Place and vineyards
Where the wines begin
DO Alella is a small appellation on the coastal hills north of Barcelona, caught between the city's expansion and the Serralada de Marina natural park boundary. That boundary has kept the agricultural land intact: the park perimeter prevents suburban development from absorbing the vineyards, which is why 68 hectares of certified-organic estate vineyard can exist this close to one of Europe's busiest cities.
The appellation sits at between 100 and 350 metres elevation on slopes that face south and southwest toward the Mediterranean. The authorised white varieties are Pansa Blanca, Garnatxa Blanca, Picapoll, Parellada, Chardonnay, and Sauvignon Blanc, with red and rosé production also permitted. Pansa Blanca, the local name for Xarel·lo, is the grape that runs through almost every bottle Alta Alella produces, from the Cava to the still white range.
In the cellar
Vineyards and cellar
Organic certification runs across all 68 hectares. In the cellar, micro-vinification is the working method: parcels, varieties, and vessels are kept separate so each batch can be evaluated and bottled individually. The approximately 50 wines produced annually are a direct result of this separation rather than blending into a smaller number of larger cuvées.
Fermentation is spontaneous across the range, relying on native yeasts from the vineyard rather than inoculated commercial strains. For the Cava, traditional method secondary fermentation happens in bottle, with lees ageing ranging from 15 to 60 months depending on the wine. For zero-dosage Brut Nature wines, there is no added sugar at disgorgement, so the Cava's character comes entirely from the grape, the soil, the lees contact, and the vintage. The Cau d'en Genís still white uses cement egg vats rather than oak or stainless steel: the clay-based cement maintains a stable temperature and allows micro-oxygenation, with natural bâtonnage stirring the lees as the vessel's curved shape circulates the wine.
Wines to know
The range in view
Cava accounts for two-thirds of Alta Alella's production and spans a range from 15 months on lees to extended reserves aged up to 60 months. All are made without added sulfites. The Mirgin line runs from Brut Nature to more extended reserve levels, with the Mirgin Reserva Brut Nature sitting at minimum 18 months on lees and zero dosage. Bone-dry, with tight yellow fruit, a saline edge, and a chalky finish that comes from the granite sand rather than any oak contact. Higher reserve tiers add complexity without sweetness: longer lees ageing builds autolytic depth while the grape's natural acidity keeps everything linear.
Celler de les Aus adds a third layer: sulphite-free still and sparkling wines made from organic estate fruit with minimum intervention. These are produced separately from the main Alta Alella range and carry their own label, but draw on the same sauló parcels and the same zero-sulfite discipline.
A useful way in
A bottle to begin with
Mirgin Reserva Brut Nature is the right first bottle. It is 100% Xarel·lo, traditional method Cava, aged minimum 18 months on lees and bottled without dosage. The grape and the soil do all the work. Saline mineral on the nose, tight citrus and a trace of green herb, fine mousse, a chalky finish that lingers. No added sugar, no oak, no sulfites. This is what Pansa Blanca from sauló granite tastes like when the cellar commits to not covering it up. It shows the estate's use of Xarel·lo, lees ageing, and zero dosage in one bottle.
