The story

Kerner was created in 1929 by crossing Trollinger (red) x Riesling (white). Yes, a red grape parent. The result is aromatic, Riesling-like wine. It's Germany's 4th most-planted white grape.

Insider story

August Herold created Kerner in 1929 at the Weinsberg research station. He crossed Trollinger (a red grape) with Riesling. The goal was Riesling-like quality with earlier ripening and disease resistance.

Kerner succeeded—it ripens 2 weeks before Riesling and resists frost. By the 1980s, it was Germany's 3rd most-planted grape.

But Kerner isn't Riesling. It lacks Riesling's aging potential and mineral complexity. Critics call it 'Riesling-lite.' Plantings have declined since 2000.

Still, good Kerner is delicious—aromatic, fresh, affordable. It's underrated.

Technical deep dive

Kerner has moderate acidity (6-7 g/L), floral and citrus aromatics, and a slightly Muscat-like character. Alcohol: 11-13% ABV.

Early ripening makes Kerner suitable for cool sites where Riesling struggles. It's popular in Alto Adige (Italy) and England.

Oak: never used. Stainless steel preserves Kerner's aromatics.

Industry secrets

Alto Adige Kerner is a secret weapon. High-altitude sites (600-800m) produce aromatic, mineral Kerner. $15-25 bottles rival $30-50 German Riesling.
