The Story

Bonarda is Argentina's 2nd most-planted red grape (after Malbec). But it's NOT Italian Bonarda. DNA testing revealed it's actually French Douce Noire—a grape thought extinct in France. Argentina's been growing it for 150 years without knowing.

Insider Story

Italian immigrants brought 'Bonarda' to Argentina in the 1800s. They thought it was Italian Bonarda (Piedmont). For 150 years, everyone believed them.

In the 2000s, DNA testing revealed the truth: Argentine 'Bonarda' is Douce Noire, a nearly extinct French grape from Savoie. It's not related to Italian Bonarda at all. Oops.

But the name stuck. Changing it would confuse consumers. So Argentina still calls it 'Bonarda' even though it's not Bonarda. Welcome to wine.

Technical Deep Dive

Bonarda (Douce Noire) has soft tannins (1,800-2,200 mg/L), moderate acidity (5-6 g/L), and plummy fruit. Alcohol: 13-14.5% ABV.

It's easier to grow than Malbec—more disease-resistant, higher-yielding. This made it a bulk grape for decades. Quality producers slash yields to 30-40 hL/ha for concentration.

Industry Secrets

Bonarda is Malbec's perfect blending partner. 10-20% Bonarda softens Malbec's tannins and adds fruit. Many 'Malbec' wines secretly contain Bonarda. Labels don't always disclose it.
