Trincadeira (Tinta Amarela)

Trincadeira thrives across Portugal, with its stronghold in the Alentejo region where it is the oldest and most widely planted variety. It also appears in Ribatejo/Tejo, the Douro, and Dão. The grape performs best in hot, dry continental climates with significant day-night temperature swings, and suits schist-based hillsides, infertile sandy soils, and well-drained terrains. It struggles in the more humid Atlantic coastal regions, where its thin-skinned berries become vulnerable to disease.

• Primary regions: Alentejo, Ribatejo/Tejo, Douro, and Dão
• Thrives on schist-based hillsides and well-drained, infertile sandy soils
• Hot, dry continental climate with day-night temperature swings suits it best
• Performs poorly in humid Atlantic coastal conditions

Trincadeira is notoriously difficult to grow. The vine produces exuberant foliage and carries high disease susceptibility, particularly to Botrytis bunch rot. Its thin-skinned berries rot quickly in humid or wet conditions, making site selection critical. Yields are high but unreliable, alternating between weak crops and overripe berries. The ripeness window is remarkably narrow, typically only a few days in late September to early October, demanding precise timing from the grower.

• Exuberant foliage and high susceptibility to Botrytis bunch rot
• Thin-skinned berries rot rapidly in humid conditions
• Yields alternate between weak crops and overripe fruit
• Optimal harvest window is just a few days in late September to early October

When grown well in dry, hot conditions, Trincadeira produces full-bodied red wines with a deep, dark color. The wines show vibrant raspberry fruit alongside herby, peppery, and spicy notes, with floral complexity adding elegance. Good natural acidity and medium-high tannins give the wines structure and aging potential. In the Alentejo, it is frequently blended with Aragonês to add freshness, while in the Douro it pairs with Touriga Nacional in both dry reds and Port wines.

• Full-bodied with vibrant raspberry fruit, pepper, herby and floral notes
• Dark color, good acidity, medium-high tannins
• Blended with Aragonês in Alentejo; with Touriga Nacional in the Douro
• Used in both dry still reds and Port wine production

Trincadeira is indigenous to the Iberian Peninsula with documentation stretching back to at least the 18th century. It has been used in Port wine production since the 1700s and holds the distinction of being the oldest and most widely planted variety in the Alentejo. Despite its long history, total plantings across Portugal have declined in recent years, a reflection of the challenges it poses in the vineyard.

• Indigenous Iberian variety documented from at least the 18th century
• Used in Port wine production since the 1700s
• Oldest and most widely planted variety in Alentejo
• Total planted area has declined in recent years despite historic prominence
