Arinto

The Story

While other grapes wilt in Portugal's heat, Arinto maintains laser-sharp acidity. From Bucelas near Lisbon to the vast Alentejo plains, this grape provides the backbone for Portugal's finest whites.

Insider Story

Arinto's origins lie in the Bucelas region, just north of Lisbon. Historical records from the 14th century mention the grape; it may have been cultivated since Roman times.

Bucelas was once famous—Wellington's troops drank its wines during the Peninsular War. The Duke reportedly shipped cases back to England. By the 20th century, the region had faded into obscurity.

Arinto's renaissance came from an unexpected place: the Alentejo. This hot, dry southern region needed high-acid varieties to balance its powerful reds and prevent flabby whites. Arinto proved perfect.

The grape now grows across Portugal—from Vinho Verde (where it's called Pedernã) to the Dão to the Alentejo. Each region produces distinct expressions, but searing acidity is the constant.

Arinto's versatility surprises. It makes everything from light, fresh Vinho Verde to rich, barrel-fermented Bucelas to sparkling wine. Few Portuguese varieties match this range.

Technical Deep Dive

Arinto produces high-acid whites (7-9 g/L) with citrus character (lemon, grapefruit), green apple, and mineral notes. The acidity is its defining characteristic.

The grape is remarkably heat-tolerant—it maintains acidity even in hot vintages that would make other varieties flabby. This makes it invaluable in warming climates.

Flavor profile varies by region: - Bucelas: Mineral, citrus, age-worthy - Vinho Verde: Light, fresh, aromatic - Alentejo: Fuller-bodied, ripe citrus, balanced by acidity

Winemaking ranges from fresh (stainless steel, early bottling) to serious (barrel fermentation, lees aging). Bucelas traditionally ages in barrel; modern styles emphasize freshness.

Arinto ages well—top examples improve for 10-20 years. The acidity provides structure; complexity develops slowly. Old Bucelas can be remarkable.

Industry Secrets

Arinto goes by different names across Portugal—Pedernã in Vinho Verde, Arinto in central/southern regions. Same grape, different expressions.

Bucelas is the historic reference point, but production is tiny. Quinta da Romeira and Quinta de Chocapalha lead the revival.

In the Alentejo, Arinto is often blended with Antão Vaz and Roupeiro. This three-way blend is the standard for Alentejo white—Arinto provides the acid spine.

The grape makes excellent sparkling wine. Espumante from Arinto can rival good Cava at lower prices.
