A Short Guide to Alentejo Olive Oil

In the Alentejo, Portugal's largest region, olive oil is more than a mere condiment. Olive oil is not just a cooking ingredient; it's a symbol of the Mediterranean diet and a testament to a region's heritage, culture, and climate.

It's a part of the soul of the land, reflecting centuries of tradition and the unique characteristics of the terrain. Here's a brief guide to understanding and enjoying Alentejo's liquid gold.

Understanding Alentejo's Olive Oil Tradition

Olive cultivation in Alentejo dates back to the time of the Romans, and over the centuries, it has developed into a cherished tradition.

The region's unique combination of sun, soil, and climate fosters the growth of various olive cultivars that produce oils with distinctive flavors - much like the region's exceptional wines!

Olive oil production in Alentejo is a similarly ancient tradition, likely influenced by the Phoenicians and Romans. The Romans, in particular, introduced advanced techniques in planting and extraction.

The Roman historian Strabo praised Alentejo Olive Oil's quality, noting its importation to Rome, as far back as 2000 years ago!

Alentejo Olive Varieties and Flavors

Alentejo's olive oils are known for their diversity in flavor, ranging from delicate and sweet to robust and peppery. While several olive varieties can be found, the four main ones cultivated in the Alentejo region include:

Galega: This is the most common olive variety in Portugal and is widely grown in Alentejo. It produces a mild and slightly sweet olive oil, perfect for various culinary uses.

Cobrançosa: This variety is known for its adaptability to different environmental conditions, and in Alentejo, it yields olive oils with balanced flavors and slightly bitter and peppery notes.

Verdeal: Verdeal olives contribute to robust and intensely flavored oils. The Verdeal variety is recognized for its complexity and is often blended with other varieties.

Cordovil: Cordovil is another significant variety in Alentejo, producing oils with fruity notes and a touch of bitterness.

The blend of these and other varieties, coupled with the specific terroir and climate of Alentejo, contributes to the diverse and distinctive olive oils the region offers.

Many producers embrace this biodiversity, blending different varieties to create unique flavor profiles, while others focus on single-varietal oils to highlight the distinct characteristics of each type.

Production Methods and Grades

In the Alentejo, the olive oil production process often combines time-honored techniques with modern technology. Cold pressing is common, a method where the oil is extracted at low temperatures to preserve the flavor and nutritional value.

Different grades of olive oil, such as extra virgin, virgin, and refined, signify varying levels of quality and flavor that cater to diverse culinary needs.

1. Extra Virgin Olive Oil: The highest quality grade, extra virgin olive oil is made from pure, cold-pressed olives, without any processing or refined oils. It contains no more than 0.8% acidity, offering a robust, complex flavor that retains the full character of the olive. Ideal for salad dressings, dips, and finishing dishes, its rich taste and aroma enhance culinary experiences.

2. Virgin Olive Oil: Similar to extra virgin olive oil, virgin olive oil is also unrefined but has a slightly higher acidity level, up to 2%. It offers a more mellow flavor and may contain minor defects. This grade is suitable for cooking and sautéing, and it maintains some of the health benefits found in extra virgin olive oil.

3. Refined Olive Oil: This grade is produced by refining virgin olive oils that have defects or higher acidity levels. The refining process removes impurities, color, and much of the natural flavor, resulting in a mild-tasting oil. Often blended with virgin or extra virgin olive oil to add flavor, it is commonly used for frying and high-heat cooking.

Beyond edible oils, there are industrially refined oils for other purposes, but I'll leave that for another article if your're interested!

Certification and Quality

Look for the PDO (Protected Designation of Origin) or DOP (Denominação de Origem Protegida) labels, which ensure the oil is produced, processed, and prepared in a specific region using traditional methods. 

Independent of the origin labels, I personally recomend Certified Organic and low acidity olive oils, with an acidity below 0.2.
