Why it matters
The producer
The first vines at Adega Mayor went into the ground in 1997, in the Alentejo municipality of Campo Maior. The project was the idea of Manuel Rui Azinhais Nabeiro, head of the Nabeiro Group, a family-owned Portuguese conglomerate. Ten years after those first plantings, in June 2007, a building by the architect Álvaro Siza Vieira opened on the estate, its white walls, clean geometry, and low horizontal form making it a distinct presence in the flat Alentejo landscape. The winery was designated Portugal's first adega de autor, a term coined for a winery conceived as a unified architectural and winemaking project. Paulo Laureano leads the winemaking team; Carlos Rodrigues is also named among the estate's winemakers.
Place and vineyards
Where the wines begin
Campo Maior sits in the Alto Alentejo, the broad inland plain that pushes east toward the Spanish border. The Alentejo is Portugal's largest wine region and its warmest, with long dry summers, intense sun, and an absence of the Atlantic cooling that moderates temperatures further west. For the vine, the consequence is full, rapid ripening and a natural generosity of fruit. The estate spreads across 350 hectares of cork oak, holm oak, riverside terraces, and farmland, of which 65 hectares across two estates are planted to vine.
In the cellar
Vineyards and cellar
The 65 vineyard hectares are split across two estates, with Herdade das Argamassas accounting for 55 of them. The Caiado range uses Aragonez, Trincadeira, and Alicante Bouschet for the red and draws on cool-temperature fermentation for the rosé, with the must clarified and fermented between 14 and 16 degrees Celsius after manual harvest, gentle destemming, and pressing. The Altitude Tinto is aged in 500-litre barrels and wooden vats called balseiros, a vessel size and material that allows slower oxygen exchange than smaller new barrique and preserves the site's fine-tannin character.
Wines to know
The range in view
The range moves from the Caiado tier through the Altitude and Reserva do Comendador bottlings, with a sparkling wine completing the portfolio. Caiado Tinto, from Aragonez, Trincadeira, and Alicante Bouschet, is the entry red: dark fruit, plum, blackberry, chocolate, and a spiced, oak-touched bouquet. Caiado Rosé, in salmon pink, opens with strawberry, raspberry, and pomegranate on the nose, and finishes dry and persistent on the palate. Altitude Tinto is the cellar's more deliberate work: ripe fruit held in check by fine tannins, with the balseiro and 500-litre barrel ageing filling the palate without adding weight. The Reserva do Comendador and the sparkling wine extend the range without departing from the Alentejo red-fruit and warmth character that the estate is built around.
A useful way in
A bottle to begin with
Altitude Tinto is the bottle to open first. It is an Alentejo red aged in 500-litre barrels and balseiros, made from estate fruit at Campo Maior and vinified to show fine tannins and ripe fruit absorbed into the oak rather than coating it. Where Caiado Tinto reads as an open, generous red, Altitude Tinto is more composed: the fruit is present but quieter, the tannin grain is finer, and the finish carries more length and definition. It shows what the estate does when the cellar team has more time and more deliberate vessel choices working in its favour.
