Zweigelt: Hybrid Variety and Red Winemaking Styles
Zweigelt is a single grape variety. Keep the distinction between its origin by crossing and the process of blending wines, and read how producers around Neusiedlersee use it for varietal and blended wines.
Questions for this course
Is Zweigelt, with two parent varieties, a blending name?

A grape variety with two parents
Zweigelt was created in 1922 by crossing St. Laurent and Blaufränkisch. Growing a grape that descends from two parents and blending wines from those two grape varieties are different things. A wine that is 100% Zweigelt does not mean it is a wine blended half and half from its parent varieties.
Established in Eastern Austria
Zweigelt is widely cultivated in Austria and is a key to understanding red wines from the east. Seewinkel around Lake Neusiedl is one such area. Locally, Salzl describes it as featuring fruitiness and gentle tannins. Once you’ve learned the grape name, distinguish the area around the lake and other regions using a map.
Used for both single-varietal wines and blends.
In Salzl, Zweigelt is used both for single-variety wines and for cuvées blending several varieties. There are also versions matured in barrels, and aromas reminiscent of vanilla are explained by barrel use. To distinguish between fruit aromas and maturation aromas, always check the blend and also the maturation vessel.

Read the explanation for each question
By answering in the selection field, you can compare your answers and explanations using the top button. Freeform responses will not be automatically graded.
How would you describe A’s blend?
Zweigelt is a single variety created by crossbreeding. Sample A is 100% Zweigelt, not a blend of wine from its parent varieties. Treat historical information about the variety and the proportions of raw materials used for winemaking separately.
What is the proportion of Blaufränkisch in B?
The blend record shows 30% Blaufränkisch in B. When explaining Zweigelt, which includes Blaufränkisch in its genetics, do not recalculate the content based on parentage. Simply state that it is a 70:30 blend of the two varieties.
What information helps clarify the vanilla-like aroma in B?
Aging in wooden barrels is noted in the documentation and may provide clues to vanilla-like aromas. When you check which barrels were used and how, your explanation becomes more specific. On the other hand, you cannot infer residual sugar or parentage blend ratios from this aroma.

This is an organized study tool based on the designated articles for this course. You can check specific facts and sources in each article.
Explain in your own words
Describe the varietal composition for A and B, and explain why you must not add information on Zweigelt's parent varieties to the blend.
Check after writing
- Did you distinguish hybridization and blending?
- Did you read B's ratio according to the reference material?
- Did you match the aromatic impression to the maturation vessel?
