Quinta do Convento is located in Serra de Montejunto (Montejunto mountain) in the heart of the Lisbon appellation, just west of Quinta de Monte d’Oiro and Quinta de Pancas, and east of Óbidos.

The 16-ectare estate is predominately planted with Touriga Nacional, the signature variety for the great wines of Portugal, namely from Douro and Dão region, where it’s believed it came from. This demanding grape variety is perfectly adapted to this region climate and soil. It produces full-bodied, well-structured, long-lived wines famous for their finesse and elegance. In keeping with a longstanding tradition, it is blended with Merlot and Syrah, which add a touch of smoothness and complexity. In certain vintages, Pinot Noir can also be counted on to contribute with the well-known charm of wines from Bourgogne.

The introduction of white Portuguese grape varieties Arinto and Fernão Pires and French grape varieties Sauvignon Blanc and Semillon, allowed to produce excellent quality white wines. Arinto confers a fresh and mineral acidity to Quinta do Convento white wine, while Sauvignon Blanc contributes with well ripen fruits and asparagus aromas. On the other end the grape variety Semillon adds complexity and a persistent buttering sensation as well as a full-body finishing. 
In years of special climacteric conditions some of that varieties are to be used in Late Harvest vintages.

Montejunto terroir features rises of calcareous limestone soils, on limestone bedrock. With an average altitude of about 500 meters and only a few kilometres away from the ocean, this terroir  is influenced by Atlantic winds.

The winegrowing attitude adopted is to intervene as little as possible and as naturally as possible in the vineyard. Only traditional viticultural practices are considered. Chemical weed killers are forbidden in keeping with environmental protection: priority is given to the vine's long-term health.

Following this reasoning, fertilisers are uniquely organic, and only used on plots that genuinely require aditional nutrition. This helps to maintain a good balance and self-regulated low yields, as well as to esteem the vines, reflect the terroir, and produce pure, natural wine. Pruning is done with the greatest of care in winter by qualified workers who are paid a on a piece-work basis rather than fixed salary. Each  vine is considered individually and treated accordingly. All these efforts result in grapes that are evenly distributed,  with an excellent sun exposure, and with utmost ventilation due to Atlantic winds,  guarantying  adequate ripeness.
