Kerner Grape Varietal: Everything You Need to Know

Geographic Distribution and Cultivation

Kerner is primarily cultivated in Germany, especially in Pfalz, Rheinhessen, and Mosel, but it has also spread to regions in Italy, Austria, Switzerland, and even Canada. Kerner was introduced in South Tyrol in the early 1970s and received Denominazione di Origine Controllata (DOC) status in 1993. Its adaptability to colder temperatures and frost makes it suitable for a range of terroirs, allowing it to thrive in diverse regions.

Regional Expressions

Kerner in Germany

• Historical Importance and Prominence: Germany is Kerner’s birthplace and remains its primary producer. In Germany, the grape has enjoyed steady popularity due to its suitability for cooler regions, its resemblance to Riesling, and its distinctive aromatic profile.
• Key Wine-Producing Regions:
  • Pfalz and Rheinhessen: These regions produce some of the finest Kerner wines, known for their balance of fruit, acidity, and minerality.
  • Mosel: In the cooler Mosel region, Kerner expresses more minerality and vibrant acidity, producing wines that are aromatic and complex.
• Stylistic Variations and Quality Levels: German Kerners range from crisp, dry wines to sweeter, late-harvest versions. Quality levels can vary, with higher quality examples often resembling Riesling in complexity, though with a slightly more floral and fruity character.

Kerner in Other Regions

Global Distribution and Cultivation: Beyond Germany, Kerner is grown in northern Italy (notably Alto Adige), Austria, Switzerland, and in cooler regions of Canada, including British Columbia’s Okanagan Valley. Kerner produces fine and distinct white wines in regions like Alto Adige, emphasizing their unique flavour profiles and cultural significance.

Notable Examples and Regional Interpretations:

• Italy: In Alto Adige, Kerner displays a more pronounced minerality and is often made in a dry style. Italian Kerners can be more full-bodied than their German counterparts, with distinct herbal notes.
• Canada: Canadian producers have successfully experimented with Kerner for ice wines, where the grape’s high acidity balances the sweetness of the dessert style.‍
• Impact on Local Wine Cultures: Kerner has supported the development of cool-climate viticulture by providing an alternative to Riesling. It has helped expand the range of white wines now available in cold regions, contributing to a greater diversity of aromatic whites.
