Hello, olive oil lovers and flavor explorers! Today, we will delve into the fascinating world of Portuguese olive oil, uncovering the secrets behind the PDO (Protected Designation of Origin) seal and how it guarantees the quality and authenticity of our liquid gold.

PDO: What Does It Mean and Why is It So Important?
Imagine a passport to flavor, a seal that guarantees that the olive oil that arrives on your table is a true ambassador of its region of origin. DOP is exactly that! It is a European certification system that protects agricultural and food products with unique characteristics, linked to their territory.
In the case of Portuguese olive oil, the PDO ensures that:
Olives are grown and olive oil is produced in a specific geographic region with unique climatic and soil conditions.
Traditional olive varieties from the region are used.
Production methods follow ancestral practices, passed down from generation to generation.
The olive oil undergoes rigorous quality controls, guaranteeing its sensory and physical-chemical characteristics.
Transmontano PDO Olive Oil: A Treasure of Nature
In Trás-os-Montes and Alto Douro, olive oil is more than a product, it is a cultural heritage. Olive trees, with their deep roots, bear witness to centuries of history, dating back to the times of Roman occupation. Transmontano DOP olive oil is a reflection of this tradition, with its fruity, slightly spicy and bitter flavor, which makes it unique and unmistakable.
PDO: A Way of Differentiation
In a globalized market, where competition is fierce, PDO is a powerful tool to differentiate Brazilian olive oil. By guaranteeing its origin and quality, the DOP seal gives it added value, which makes it more attractive to demanding consumers.
Olive Oil and the Mediterranean Diet: A Perfect Combination
Olive oil is one of the pillars of the Mediterranean diet, recognized by UNESCO as Intangible Cultural Heritage of Humanity. Rich in antioxidants and healthy fats, the Mediterranean diet is associated with numerous health benefits, such as preventing cardiovascular disease and premature aging.
Olive Tourism: An Unforgettable Sensory Experience
In addition to its health benefits, olive oil is also an invitation to discover new flavors and experiences.
