Features and Production of Trás-os-Montes Olive Oil
Olive Varieties and Production Area
The Trás-os-Montes region - covering Bragança, Vila Real, and Guarda - is known for its distinct microclimate. Thanks to its rolling hills and numerous streams, this area is perfectly suited for growing olives. Protected under PDO standards, this microclimate plays a key role in ensuring the high quality of Trás-os-Montes olive oil [1].
This olive oil is made from a blend of Verdeal Transmontana, Madural, Cobrançosa, and Cordovil olives. Each variety adds its own unique element to the oil's flavor. These olives are grown in key areas like Mirandela, Vila Flor, Alfândega da Fé, and Bragança, forming the backbone of this PDO-certified product [1].
Harvesting and Processing Methods
Olives are harvested in late autumn or early winter, ensuring they are at their peak. After harvesting, they are washed, crushed into a paste, and processed at 30–32°C using modern centrifuge technology. This method helps extract the oil without compromising its quality. The timing of the harvest is critical; olives are picked when their skins turn black and their flesh shifts from green to violet [1][2].
Flavor Characteristics
Trás-os-Montes olive oil is known for its balanced flavor. It combines a touch of sweetness with mild bitterness and a pleasant peppery finish. Its fruity taste, highlighted by almond undertones, sets it apart from other oils in the region [1].
These qualities are a testament to the region's centuries-old olive oil-making traditions. By blending traditional practices with modern techniques, producers ensure that Trás-os-Montes olive oil continues to meet the high standards of its PDO certification [1].
History and Importance in the Region

Over time, production methods transitioned from traditional to more modern approaches. Early techniques involved manual harvesting, granite tanks, and presses powered by oxen.

Beyond its culinary value, olive oil production is a key economic driver, providing jobs across the region and sustaining age-old farming practices.
