Welschriesling: interpreting dry and botrytized sweet wine analytical values
Compare Welschriesling dry and botrytized sweet wine using data from two producers. Practice reading residual sugar and alcohol separately.
Questions for this course
If alcohol levels are similar, will sweetness also be similar?
Before you start reading, briefly jot down your thoughts. You will rephrase them at the end.

Examples of dry wines from Burgenland
The 2025 Welschriesling made by Familie Weiss in Gols is a white wine fermented in stainless steel tanks and matured on the lees. According to the source, residual sugar is 3.4g/L and alcohol is 11.2%. Reading together about containers and analytical data provides a more concrete comparison than using only the variety name.
Example of a concentrated, sweet style from fruit
Allacher’s 2020 Trockenbeerenauslese is described as being concentrated through noble rot and fruit drying. With 147g/L residual sugar and 11.3% alcohol, it differs greatly in sweetness from dry styles of the same variety. The difference in sweetness cannot be predicted from the alcohol content alone.
Differences in winemaking despite similar values
Although the alcohol content of the two wines is similar, the grape condition and maturation differ. Furthermore, with different producers and vintages, this isn't an experiment changing only one factor. Compare them as examples of the same grape variety used in different styles.

Welschriesling source reading: interpret dry and botrytized sweet wine analytical values
This comparative material is based on sources. Please distinguish between the characteristics of grape varieties and the conditions of each region or product as you read.
The table is a summary of the sources below. Values given with product names or vintages are based on data for those specific items.
| Comparison items | Weiss 2025 | Allacher 2020 |
|---|---|---|
| Residual sugar | 3.4g/L | 147g/L |
| Alcohol | 11.2% | 11.3% |
| Winemaking | Tank fermentation, lees maturation | Noble sweet wines and barrel aging |

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.
What is the major difference in analysis values between the two wines?
Residual sugar is 3.4g/L and 147g/L. Even with similar alcohol content, sweetness and dryness are very different.
What is the condition of the grapes described for Allacher’s sweet wine?
The materials explain both noble rot grapes and concentration on the vine.
What conditions are not aligned in the comparison?
These are white wines of the same grape variety, but the producer and vintage differ. You cannot attribute all the differences to a single part of the process.
