Arinto — Portugal’s Signature High-Acid White
Arinto is one of Portugal’s most important and versatile white grape varieties, prized above all for its vibrant acidity, freshness and structure. Long associated with the historic wines of Bucelas near Lisbon, Arinto is now grown across the country — from Vinho Verde to Tejo, Lisboa and even Alentejo — and is used in styles ranging from crisp, unoaked whites to more complex, ageworthy bottles and even sparkling wines.
In the vineyard, this variety stands out for its ability to retain high acidity even in warm conditions, making it exceptionally valuable in hotter regions where other grapes might lose freshness. Arinto clusters are typically medium-sized with thick-skinned berries, contributing both acidity and texture to the wine.
The wines are usually light to medium-bodied with brilliant acidity, giving them a lively, refreshing profile. Common flavour and aroma notes include citrus (lemon, lime), green apple and grapefruit, often with a mineral edge that adds tension and crispness on the palate. In richer or barrel-aged expressions, nuances of beeswax, almond and flint can emerge, adding depth without sacrificing freshness.
Arinto’s natural acidity and backbone make it a popular blending partner as well as a compelling varietal wine. It pairs beautifully with seafood, grilled fish, salads, goat cheeses and dishes where acidity lifts the flavours, and its structure also allows the best examples to age gracefully for several years.
