Zind-Humbrecht: Comparing Rieslings from the Same Year
A domaine based in Turckheim, Alsace, with several grands crus. They publish technical information such as residual sugar, acidity, and yield by vineyard, variety, and vintage.
Compare the analysis values of the two 2022 Rieslings, and organize the points that cannot be explained by geology alone.
Questions for this course
Will Riesling from a warm year reach the same numbers in every vineyard?
Before you start reading, briefly jot down your thoughts. You will rephrase them at the end.

Granite and volcanic soils
Compare the Rieslings from Brand (Turckheim) and Langen Clos Saint Urbain (Thann) in 2022. Brand is described as granite-based, while Langen has volcanic sedimentary rock. Even if grape variety and vintage match, location conditions differ.
Residual sugar and alcohol
Brandt: residual sugar 1g/L, alcohol 13.6%. Langen: 1.4g/L, 12.8%. Even when both are introduced as dry, their analysis values are not identical. Instead of attributing solely to geology, consider record of ripeness and fermentation as well.
Yields are not consistent.
Yield is Brandt 45hl/ha, Langen 25hl/ha. This is not simply an experiment changing location, but a comparison of two wines with several differing factors including yield. Record the differences evident from numerical values separately from tasting impressions.

Zind-Humbrecht Document Interpretation: Comparing Rieslings from the Same Year
Compare the stated conditions in the documentation. Numbers specifying vintages should be treated as information for that specific year.
This summarizes materials published by producers, regional groups, and importers. Each source includes the publisher and the date the material was checked.
| Comparison items | What can be determined from the materials | Ability to distinguish by reading |
|---|---|---|
| Brand 2022 | Residual sugar 1g/L, 13.6%, 45hl/ha | Granite vineyards |
| Langen 2022 | Residual sugar 1.4g/L, 12.8%, 25hl/ha | Land of volcanic origin |
| Common points | Same producer: variety, vintage | Other conditions besides place also differ. |

Which conditions are standardized?
First check the common conditions for the comparison.
What does 1.4g/L residual sugar mean?
Always read the wine name together with the unit.
Can these two bottles be treated as an experimental comparison based solely on geology?
Multiple factors are changing simultaneously. Even with Riesling from the same 2022 vintage, Brandt and Langen differ in yield, residual sugar, and alcohol. Soil is one comparison point, but the conditions are not sufficient to conclude that differences in the data are attributable to soil alone.

Explain in your own words
Compare the analysis values of the two 2022 Rieslings, and state points that cannot be explained by geology alone.
Check after writing
- Did you specify the label, vintage, and scope of materials to be compared?
- Did you distinguish and explain the three items in the table?
- Did you separate verified facts from points to check further with additional references or tasting?
