Silvaner: Spread across regions and synonyms in Valais
Consider the status of Silvaner in Franken and Rheinhessen. In Switzerland’s Valais, it is also known as Johannisberg and made as both dry and sweet styles.
Questions for this course
Are the regions with the largest vineyard area the same as those where a grape has the highest proportion?

Differences that emerge when comparing area and proportion
DWI's grape variety overview uses 2022 vineyard surface figures. Rheinhessen is listed as the region with the largest area planted to Silvaner, while Franconia (Franken) has the highest percentage of vineyard area devoted to Silvaner. 'Area' refers to the total hectares of a variety; 'percentage' is its ratio to the region’s total vineyards. Both help understand a region, but the rankings do not always match.
From subtle aromas to breadth in winemaking styles
Silvaner is noted for its delicate aromas reminiscent of herbs and gooseberry, and gentle acidity. DWI introduces not only light-bodied wines, but also fuller, barrel-aged whites and sweet wines as well. Don’t assume that a subtle aroma means a light taste—if you check the acidity, weight, and sweetness separately, you will understand the differences in winemaking.
In Valais, this means Johannisberg.
In Switzerland's Valais, Silvaner is called Johannisberg. According to the official regional introduction, it is grown on light schist soils and alluvial fans rich in gravel, and used to make both dry and sweet styles. When you see Johannisberg on a label, first check the country and region. If you read it as a local alternate name for Valais, you can compare it with the Silvaner you studied in Germany.

Reading on Silvaner: its spread across regions and synonyms in Valais
Using cultivation areas for two fictional regions, consider why rankings change depending on area and proportion.
These are hypothetical figures for learning. Assume the vineyard sizes were calculated using the same year and definition. Not based on statistics of real wine regions.
| Item | Region A | Region B |
|---|---|---|
| Cultivated area of all varieties | 10,000 ha | 2,000 ha |
| of which Silvaner | 1,000 ha | 500 ha |
| Compilation conditions | Same year / Same definition | Same year / Same definition |

Which region has the largest vineyard area planted to Silvaner?
Region A is 1,000 ha, while Region B is 500 ha, so the vineyard area of Silvaner is greater in A. The comparison here is by area, not proportion. Since the regions differ in total size, this ranking alone does not explain each region’s varietal structure.
In which region is the proportion of Silvaner highest?
Region A’s 1,000 ÷ 10,000 is 10%; Region B’s 500 ÷ 2,000 is 25%. Even though Region B has a smaller total Silvaner area, its share of the region’s total vineyard is higher. To calculate ratios for both regions, use the total vineyard area for each as the denominator.
What can be properly said from this hypothetical document?
Area and proportion are two different ways to explain the spread of a variety within a region. They do not directly indicate quality or taste. Also, the 25% calculated here is for the hypothetical region B. For actual regions, use statistics with confirmed sources and harvest years.

Explain in your own words
Compare the area and proportion of Silvaner in two regions. Write the reason why you need to look at both when describing the characteristics of an origin.
Check after writing
- Did you correctly calculate area and proportion?
- Was the total area of the relevant region used as the denominator?
- Did you confuse imaginary numerical values with actual regional statistics?
