Bical
How to Say It
Portugal's high-acid white grape, the backbone of Bairrada sparkling wine and a variety with surprising aging potential.
Bical is a native Portuguese white grape prized for its naturally high acidity and crisp citrus and stone fruit character. It thrives in the cool, Atlantic-influenced Bairrada region, where it drives over 50% of Portugal's sparkling wine production. With time, it develops honeyed complexity reminiscent of aged Riesling.
- Native pale yellow-skinned white grape variety from the Bairrada region of Portugal
- Nicknamed 'Borrado das Moscas' (fly droppings) due to distinctive brown freckles on the grape skin
- Early ripening variety, typically harvested in August
- DNA analysis confirms it is a natural cross between Arinto do Dão (Malvasia Fina) and an unknown father variety
- Used in still, sparkling, and fortified wine production
- Bairrada produces over 50% of all Portuguese sparkling wine; the region's first sparkling wine dates to 1890
- Responds well to oak aging, extended lees contact, and develops honeyed, Riesling-like complexity with bottle age
Origins and Identity
Bical is a native white grape variety of Portugal, rooted in the Bairrada region within the broader Beiras zone. It also appears in Dão. The grape carries a memorable nickname, Borrado das Moscas, meaning 'fly droppings' in Portuguese, a reference to the brown freckles that appear on its pale yellow skin. DNA analysis has since confirmed that Bical is a natural cross between Arinto do Dão (also known as Malvasia Fina) and an unidentified father variety, placing it firmly within Portugal's rich indigenous grape heritage.
- Native to the Bairrada region within the Beiras wine zone
- Also grown in Dão; registered under multiple synonyms including Arinto de Alcobaça and Barrado das Moscas
- DNA-confirmed cross between Arinto do Dão (Malvasia Fina) and an unknown parent
- Pale yellow-skinned grape with distinctive brown freckles on the skin
Climate and Terroir
Bical thrives in the cool, temperate climate of Bairrada, where cooling breezes off the Atlantic moderate temperatures and help preserve the grape's characteristic high natural acidity. Soils in the region are predominantly calcareous and clay-based, contributing to the mineral notes found in wines made from this variety. This combination of cool conditions and mineral-rich soils makes Bairrada an ideal home for a grape that depends on freshness and structure.
- Cool, temperate climate with Atlantic cooling breezes
- Calcareous and clay-dominant soils
- Mineral notes in the wine reflect the soil composition
- Climate preserves natural acidity critical for sparkling wine production
Role in Sparkling Wine
Bical's most important commercial role is in sparkling wine production. The Bairrada region produced its first sparkling wine in 1890, and today accounts for over 50% of all sparkling wine made in Portugal. Bical's high acidity makes it a natural fit for the traditional method, and it is commonly blended with Arinto and Baga to achieve balance and complexity in these wines. The early ripening cycle, with harvest typically occurring in August, allows producers to capture peak acidity before sugar levels climb too high.
- Bairrada produced its first sparkling wine in 1890
- Region now accounts for over 50% of Portugal's total sparkling wine production
- High acidity makes Bical ideal for traditional method sparkling wine
- Commonly blended with Arinto and Baga in Bairrada sparkling wines

Beyond sparkling production, Bical produces crisp and refreshing still white wines with aromas of peach, apricot, green apple, and flowers. In warmer vintages, tropical fruit notes emerge. The variety responds well to oak aging and extended lees contact, which adds texture and complexity. With several years of bottle age, Bical can develop a honeyed character and structural depth comparable to aged Riesling, making it one of Portugal's more rewarding white grapes for those willing to cellar it. Bical is also used in fortified wine production.
