Bonarda

The name Bonarda refers to three genetically unrelated grape varieties in three different wine regions, a source of recurring confusion in wine education and labeling. Argentine Bonarda is genetically Douce Noir, a variety originating in the Savoie region of France and also known as Charbono in California; DNA analysis confirmed this identity in the early 2000s through work by the José Vouillamoz/Robinson grape genetics group and Argentine and Californian university research programs. Italian Bonarda Piemontese (commonly called simply Bonarda in Piedmont, Italy) is genetically Croatina, an unrelated Italian variety used primarily in the Oltrepò Pavese region of Lombardy and in the Colli Piacentini of Emilia-Romagna for soft, fruity, often slightly sparkling red wines. Bonarda dell'Oltrepò Pavese, despite its name, is yet another distinct grape (technically Uva Rara) historically blended in Oltrepò Pavese DOC red wines. The three varieties produce stylistically different wines: Argentine Bonarda is dark, soft, juicy, ripe-fruited, and approachable; Italian Bonarda Piemontese (Croatina) produces deeply colored, lightly sparkling, soft-tannic wines in the Lombardy frizzante tradition; and Bonarda dell'Oltrepò Pavese (Uva Rara) supplies blending capacity to broader Oltrepò DOC blends. The shared name across three unrelated grapes is a recurring teaching example of the disconnect between historical varietal names and modern DNA-confirmed varietal identity. For this article, Bonarda refers to the Argentine Douce Noir/Charbono variety; the Italian Bonarda Piemontese (Croatina) and Bonarda dell'Oltrepò Pavese (Uva Rara) are unrelated grapes covered separately under their own canonical names.

• Argentine Bonarda = genetically Douce Noir (French Savoie origin) = Charbono (California name); DNA confirmed early 2000s by José Vouillamoz/Robinson grape genetics group
• Italian Bonarda Piemontese = synonym for Croatina; unrelated Italian variety used in Oltrepò Pavese (Lombardy) and Colli Piacentini (Emilia-Romagna) for soft, lightly sparkling red wines
• Bonarda dell'Oltrepò Pavese = synonym for Uva Rara; yet another distinct Italian grape historically blended in Oltrepò Pavese DOC red wines
• Three unrelated grapes share the Bonarda name; this article covers the Argentine Douce Noir/Charbono variety only; the Italian varieties are covered under their canonical Croatina and Uva Rara names

Argentine Bonarda almost certainly arrived in South America with Italian immigrants who arrived in the late 19th and early 20th centuries, predominantly from Piedmont and Lombardy where the Italian Bonarda Piemontese (Croatina) and Bonarda dell'Oltrepò Pavese (Uva Rara) were familiar working-class wine grapes. The mass Italian immigration to Argentina between 1880 and 1920 was one of the largest demographic movements of the era, with approximately 3 million Italians arriving over four decades and concentrating heavily in Buenos Aires, Mendoza, San Juan, and the Cuyo wine regions. These immigrants brought familiar vine cuttings, identifying them by their Piedmontese or Lombard names; the variety that became Argentine Bonarda was likely cuttings of French Douce Noir that had circulated through northern Italian nurseries and been misidentified as Italian Bonarda before transport to Argentina. The misidentification persisted through the 20th century, with the variety entrenched in Argentine wine labeling as Bonarda and the assumption of Italian origin going unchallenged until DNA analysis in the early 2000s revealed the true French Douce Noir genetic identity. The Cuyo wine industry has continued to use the Bonarda name despite the disproved Italian origin, because the name is established in international markets and consumer recognition and changing it would require significant labeling reform. Some Argentine producers have begun explicitly noting the Douce Noir genetic identity on back labels or marketing materials, particularly for export-focused premium expressions.

Argentine Bonarda plantings concentrate in the hot lower-elevation Cuyo zones: Mendoza East (specifically the San Martín, Junín, Rivadavia, and Maipú East departments), San Juan Tulum Valley, the La Rioja Argentina Famatina Valley, and Catamarca Tinogasta. These warm valley-floor sites at 600 to 900 meters above sea level produce ripe, soft, juicy Bonarda with the variety's signature dark fruit and approachable tannic structure. Old-vine Bonarda plantings dating to the early 20th century survive in Mendoza East (particularly San Martín and Junín, where the variety has been a workhorse since the Italian immigration era), in San Juan Tulum (where it accompanies the larger Syrah and Malbec plantings), and in the La Rioja Famatina Valley (where Vichigasta and Nonogasta old-vine sites supply premium boutique production for La Riojana Cooperativa and Valle de la Puerta). The premium revival tier increasingly explores higher-altitude Bonarda plantings in the Uco Valley and other premium Mendoza zones at 1,000+ meters, where altitude-driven freshness adds structural definition to the variety's naturally soft character. The variety is generally not planted at the highest premium altitudes (Pedernal Valley, Gualtallary, Cafayate, Fiambalá) where Malbec, Cabernet Franc, and Cabernet Sauvignon dominate, but several boutique producers have demonstrated that high-altitude Bonarda can produce serious premium expressions when yield management and viticulture investment match the altitude.

Argentine Bonarda produces wines with deep ruby color, soft tannins, ripe juicy fruit, and moderate to moderate-plus alcohol levels. The classic varietal profile centers on black cherry, plum, blueberry, blackberry, and faintly spicy notes (clove, allspice, and a faintly peppery finish), with red fruit lift on the entry and a smooth approachable structure on the palate. The variety's natural acidity is moderate (lower than Malbec or Cabernet Sauvignon), and the soft tannins make Bonarda wines approachable young without extensive aging requirements. Premium expressions show more concentration and complexity, with additional notes of dried herbs, leather, tobacco, dark chocolate, and earthy mountain-herb character at the old-vine and high-altitude tier. The wines pair exceptionally well with the Argentine asado tradition (grilled meats, chimichurri, and chorizo), with the soft structure and ripe fruit complementing rather than competing with the charred protein. Bonarda also blends well with Malbec to soften the larger variety's tannic structure, and many Argentine blended reds feature 10 to 30 percent Bonarda for this softening effect. Single-varietal Bonarda has historically been less prestigious than Malbec but has grown significantly since the 2000s as the premium revival tier has demonstrated the variety's standalone quality potential.

The Argentine Bonarda premium varietal revival began in the early 2000s and accelerated through the 2010s, led by a group of premium-focused producers who recognized the variety's quality potential beyond its historical blending and volume role. Altos Las Hormigas (founded 1995 by Italian winemaker Alberto Antonini and Bordeaux consultant Attilio Pagli, with Mendoza-based viticulture team led by Pedro Parra) released the Altos Las Hormigas Sin Fronteras Bonarda from old-vine Mendoza East and Famatina plantings as one of the first internationally recognized premium varietal Bonardas. Bodega Aleanna (Catena Zapata's small-scale premium project led by Alejandro Vigil) produces the El Enemigo Bonarda from old-vine Mendoza East, displaying significant concentration, structure, and aging potential at a premium price point. Matias Riccitelli's Sin Filtrar Bonarda showcases the variety with unfiltered, minimal-intervention winemaking that emphasizes its naturally soft and juicy character. Other notable premium Bonarda producers include Bodega Mendel (Mendel Unus and Lunta Bonarda), Bodega Catena Zapata (Catena Alta Bonarda), Bressia (Bressia Conjuro), and several boutique projects in Uco Valley and the Famatina Valley. Tim Atkin MW's Argentine reports increasingly feature Bonarda in the premium varietal rankings alongside Malbec, with the Bonarda quality conversation now firmly established in international wine criticism. The variety is increasingly seen as a distinctively Argentine premium varietal that anchors regional identity alongside Malbec, Torrontés, and the Criolla heritage complex.
