Arinto

Arinto's first documented mention dates to 1712, when Vincencio Alarte referenced it in 'Agricultura das Vinhas.' The variety is believed to have originated in the Estremadura region near Lisbon and has been cultivated across Portugal for centuries. Historical texts from the Elizabethan era may reference it as 'Charneco,' and both Thomas Jefferson and the Duke of Wellington were known admirers in the 18th and 19th centuries. After centuries of quiet importance within Portugal, Arinto gained international prominence in recent decades, with growers as far as Australia adopting it.

• Possibly referenced as 'Charneco' in Elizabethan-era texts

Arinto thrives across a remarkable range of Portuguese regions, from the cool, granitic soils of Vinho Verde in the northwest to the hot, dry continental conditions of the Alentejo in the south. It is the backbone grape of the Bucelas DOC, where it grows in clay-limestone soils just north of Lisbon. The Douro Valley sees it planted at elevations above 600 metres on schist and granite soils, and it also appears in Tejo and the Azores. Beyond Portugal, Arinto is grown in Spain's Extremadura and has established a foothold in Australia, with 27 producers recorded by 2023.

Arinto is a late-ripening variety producing medium-sized yellowish berries in tightly packed bunches. Its standout agronomic trait is the ability to retain high natural acidity even when grown in hot, dry climates, a characteristic that makes it exceptionally valuable for blending in warm-region white wines. The main viticultural challenge is susceptibility to oidium (powdery mildew) in wet weather, which requires careful canopy management in humid growing conditions such as those found in Vinho Verde.

• Late-ripening variety with medium-sized yellowish berries in tightly packed bunches
• Retains high acidity even in hot, dry conditions
• Susceptible to oidium in wet weather
• Frequently used in white blends to boost acidity in warm regions

Arinto produces light to medium-bodied dry white wines defined by bright citrus and mineral flavors and a firm, refreshing acidity. It is made as a single-varietal wine, used in blends, and vinified as sparkling wine. In Bucelas, where it must comprise at least 75% of the blend, it produces wines often compared in character to Chablis-style Chardonnay. With age, Arinto develops secondary notes of honey, nuts, and tropical fruit, and quality examples can age gracefully for seven or more years.

• Light to medium-bodied dry whites with citrus, mineral, and high-acid character
• Produced as still, blended, and sparkling wines across multiple DOCs
• Bucelas DOC requires a minimum 75% Arinto
• Ages 7 or more years, gaining honey, nut, and tropical fruit complexity
