Alentejo White Grapes

Alentejo covers approximately one-third of Portugal and sits in the country's south, largely shielded from the cooling influence of the Atlantic. Summers are hot and dry, regularly reaching 40°C (104°F), with over 3,000 hours of sunshine annually. Winters are mild and wet. The region encompasses around 56,500 acres of vineyards across a diverse landscape, with soils ranging from schist and granite to clay, limestone, and marble. Elevation plays a major role in style, from low-lying southern subregions to Portalegre in the northeast, which climbs to almost 3,330 feet and produces noticeably cooler, fresher wines.

• Over 3,000 hours of sunshine annually with summer temperatures reaching 40°C
• Soils include schist, granite, clay, limestone, and marble across eight subregions
• Portalegre sits at nearly 3,330 feet elevation, producing fresher wines than southern subregions
• Atlantic influence is largely blocked, intensifying the continental heat effect

Five white varieties define Alentejo's white wine identity. Antão Vaz is the anchor grape, producing full-bodied wines with tropical fruit and minerality; its heat and drought resistance makes it uniquely suited to the Alentejo climate. Arinto is the counterbalance, bringing high acidity and green apple and citrus notes that are essential in a warm-climate blend. Roupeiro adds an aromatic, honeyed dimension and is valued for its disease resistance. Fernão Pires, the most widely planted white grape across all of Portugal, contributes intense aromatics with lime and lemon character. Verdelho rounds out the five with high alcohol, high acidity, honeysuckle aromas, and nectarine and citrus flavors.

• Antão Vaz: heat-resistant, full-bodied, tropical fruit and minerality
• Arinto: high acidity, green apple and citrus, critical blending component
• Roupeiro: aromatic, honey character, disease-resistant
• Fernão Pires: most widely planted white in Portugal, lime and citrus aromatics
• Verdelho: high alcohol and acid, honeysuckle aromas, nectarine and citrus flavors

Blending is the defining winemaking philosophy for Alentejo whites. In a region where summer heat can easily strip acidity and flatten texture, combining the body and richness of Antão Vaz with the sharp acidity of Arinto or the aromatic lift of Fernão Pires produces wines with genuine balance. The result is a white wine style that ranges from light to full-bodied, with tropical fruit, citrus, floral, and mineral notes, good structure, and increasing aging potential. White wine production has been growing steadily, approaching 25 to 37 percent of output at some estates, reflecting rising demand for Alentejo whites both domestically and internationally.

• Antão Vaz provides body and richness; Arinto provides freshness and length
• Blending compensates for the heat's tendency to reduce natural acidity
• White wine output is rising, reaching up to 37 percent at some estates
• Wines range from light to full-bodied with tropical, citrus, floral, and mineral profiles

Winemaking in Alentejo stretches back to at least the 7th century B.C., when Romans produced wine across this landscape. The region's most distinctive historical legacy is the Talha tradition, an amphora-based winemaking method over 2,000 years old that still continues today. The 20th century brought decline as production fell under cooperative control, but from the 1980s onward, private investment and modernization revitalized the region. Today, Alentejo is also recognized for the Wines of Alentejo Sustainability Programme (WASP), considered one of Europe's most rigorous sustainability initiatives.

• Romans made wine in Alentejo from at least the 7th century B.C.
• Talha amphora winemaking is over 2,000 years old and still practiced today
• Private investment from the 1980s onward reversed decades of cooperative-era decline
• The Wines of Alentejo Sustainability Programme (WASP) is among Europe's most rigorous
