2025 Argentina (Mendoza) Vintage

The foundations were good. Winter brought solid snowfall and cold temperatures across Argentina, which set up a strong fruit set and yield and improved the outlook after the short 2023 and 2024 crops. Spring rains were generous and reduced the threat of spring frost. Sebastián Zuccardi, winemaker at Zuccardi, said those initial rains set the tone for a cool start to the season, with water-laden soils giving the vines a strong and energetic beginning. The season did not stay linear. Heatwaves in January and early February triggered a rapid advance in ripening and produced some of the earliest harvests on record, with Malbec in particular ripening up to three weeks early. Juan Pablo Murgia, winemaker at Argento, harvested Malbec in Agrelo on 17 February and called it a historic record in terms of early harvest. The compression created both logistical and winemaking problems: whites and some red varieties were squeezed into the same picking window, and as Murgia explained, the heatwaves halt maturation but dehydrate grapes and increase sugars, so the year demanded very good vineyard and winemaking management, with careful macerations for early-picked reds whose tannins were not fully ripe. Most Mendoza producers had their whites in before the end of February, which turned out to be the dividing line. From mid-February onward a sudden drop in temperature and several extended rain showers halted ripening. Zuccardi said the rain and lower temperatures slowed the ripening of certain varieties and regions and brought picking back to more typical dates, with delays in sugar accumulation in some cases. The fetched sources record no hail, frost damage or smoke exposure in Mendoza in 2025, and none is asserted here.

• Good winter snowfall and cold temperatures gave a strong fruit set and yield, better than 2023 and 2024
• Generous spring rains reduced spring frost risk and left water-laden soils for a cool, energetic start
• January and early February heatwaves advanced ripening sharply; Malbec up to three weeks early
• Agrelo Malbec picked on 17 February at Argento, described as a historic early-harvest record
• Whites and some reds squeezed into one window; heat halted maturation while dehydrating berries and raising sugars
• Most Mendoza whites were in before the end of February
• From mid-February a temperature drop and extended rain showers halted ripening and returned picking to typical dates

The staggering of two very different harvest windows made parcel selection the decisive skill of the vintage. Producers found they had to pick by region rather than by variety, and the terroir-focused soil studies that Mendoza's top wineries have invested in over recent years paid off directly. Zuccardi described the mechanism plainly: soil-based parcel selection lets a team move quickly where needed and wait in areas that ripen more slowly, and in years like this vineyard management is essential. In Gualtallary and Altamira his team started picking early, especially on the more stony soils, which ripened very quickly, while medium and deeper soils took longer. In San Pablo, harvest took place at a normal time. The scrambled order of the season showed up on a larger scale too: Murgia completed harvest in San Juan after Mendoza, a reversal of the usual sequence and a fair measure of how unpredictable the year was.

• Parcel selection by region rather than by variety was critical to top quality
• Gualtallary and Altamira stony soils ripened very quickly and were picked early; deeper soils took longer
• San Pablo harvested at a normal time
• San Juan finished after Mendoza, reversing the typical order

The two halves of the season left two distinct styles in the cellar. Reds harvested before the rains are more fruit-driven but show vibrant acidity and a floral character. Reds harvested after the rains reflect the cooler temperatures, with lower alcohol levels and a more austere profile. Buyers reading the vintage should expect that difference to run right through 2025 Mendoza reds rather than average out. The bigger surprise is the overall register of the wines. Despite warm temperature averages across the year, Murgia said some of the wines fermenting were taking on more of the character of a cool year. Whites did well, helped by being picked early and cleanly before the weather turned. Zuccardi's verdict on the year was direct: a very good vintage, with energy, freshness, good balance and balanced alcohol levels. Amanda Barnes MW, writing for the drinks business, read 2025 as a vintage that reflected Argentina's increasingly changeable weather but also the growing precision of the country's viticulturists and winemakers, the best of whom let elegance win out over heat.

• Reds picked before the rains: fruit-driven, vibrant acidity, floral character
• Reds picked after the rains: lower alcohol, cooler, more austere profile
• Warm averages yet wines fermenting with the character of a cool year
• Zuccardi's summary: energy, freshness, good balance and balanced alcohol levels

The early start was national. In northern Argentina, Paco Puga, a consultant across the region and winemaker at El Porvenir, reported an early harvest in the central Calchaquí Valleys with Malbec picking starting in early February, while the higher-altitude, cooler parts ran to more normal timing with harvest from late March into early April. Javier Grane of Bodega Colomé said the Calchaquí Valleys had very good yields and excellent quality with very healthy grapes. Puga reported northern reds with balanced alcohols, lovely freshness and good concentration, though Torrontés was hit harder by the heatwaves and came in less fresh. In the far south, Murgia, who also makes wine at Otronia, described an exceptional vintage with yields 20 per cent lower than the previous year because of strong winds, reporting Malbec at 14.3 per cent potential alcohol with 11 grams per litre total acidity before malolactic and a pH of 3.1. In Chubut, Sofia Elena of Contra Corriente said a dry summer offered a promising yield and good quality fruit. Away from the classic regions, Wines of Argentina reported a balanced climate and healthy vineyards in Córdoba, where a warm summer advanced the shorter-cycle varieties and March rains slowed the later ones without hurting quality, while Entre Ríos saw high early-summer temperatures and water stress trim volumes slightly without affecting quality.

• Central Calchaquí Valleys picked Malbec from early February; higher, cooler sites ran late March into early April
• Northern reds showed balanced alcohols and freshness, though Torrontés suffered from the heatwaves
• Otronia in the far south: yields down 20 per cent on wind, Malbec at 14.3 per cent potential alcohol, 11 g/l total acidity, pH 3.1
• Córdoba reported a balanced climate and healthy vineyards; Entre Ríos lost a little volume to heat and water stress
