Caixeiro Signature is a Organically certified extra virgin olive oil produced in the PDO/PDO region of Trás-os-Montes in northeastern Portugal. This mountainous, rural region is home to many small villages and a peaceful, natural environment. The combination of altitude, wide temperature variations, mineral-rich soils, and clean air creates the foundation for olive oil with a clear origin and a balanced character.
The oil is produced by Caixeiro (Soresa) , a family-owned company that consciously chooses small-scale production over mass production. Each harvest is handled individually, and production is limited to a maximum of 3,000 bottles , ensuring control, consistency, and attention to quality at every step of the process.
The Caixeiro Signature is a carefully crafted blend of Cobrançosa, Madural, and Verdeal Transmontanas , traditional Portuguese olive varieties characteristic of this region. Together, they produce a mildly fruity extra virgin olive oil with fresh green notes, a subtle bitterness, and a slightly peppery finish. This peppery note is typical of high-quality extra virgin olive oil and indicates the presence of natural antioxidants, such as polyphenols .
The olives are harvested by hand and pressed within 12 hours of picking , a crucial step in preserving their flavor, aroma, and quality. With a very low acidity of less than 0.2%, this oil easily meets the strictest standards for extra virgin olive oil. The oil is partially filtered to remove impurities while preserving its flavor and natural properties.
This organic extra virgin olive oil has won numerous awards at international olive oil competitions , including competitions in Amsterdam, New York, and Japan, and was named Best in Class within the Portuguese PDO olive oils. It is prized by both professionals and home cooks for its balance, accessibility, and consistent quality .
This is an olive oil you'll reach for often. It's excellent in cold dishes like salads, raw vegetables, and as a garnish on a plate, but it's also very suitable for hot preparations . Not overpowering, but invigorating—an extra virgin olive oil for those who consciously choose certified quality, small-scale production, and authentic provenance .
