READ · COMPARE · EXPLAIN
To what extent can you compare lees contact time?
From Japanese Koshu and Uruguayan Albariño, read both the range described for maturation and the conditions that are not mentioned.
Questions for this course
Can you directly compare the duration of 'until spring' and '3–6 months'?
Before you start reading, briefly jot down your thoughts. You will rephrase them at the end.

To what extent can you compare lees contact time: Read the information.
Read the document below, first write your own thoughts, then answer the questions. After answering, compare with the explanation and try to revise your response.
The official documents have been summarized for study purposes. The producer's figures refer to the stated label and vintage, and do not indicate country-wide regulations.
Information not included in the table has not been confirmed. You can check the original explanation and applicability in articles on each country and in the listed sources at the end.
| Subject | What to check in the documentation | Conditions for distinguishing by reading |
|---|---|---|
| Lumière Koshu Sur Lie 2024 | No racking until spring | Exact date and months are not in this summary |
| Garzón Albariño Reserva 2023 | Fine lees for 3 to 6 months | Indication as a range. Not a fixed 6 months. |
| Stirring frequency | This summary does not mention it. | Just having contact does not confirm the frequency |

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 accurately describe Kōshū’s skin contact period in months?
The description 'spring' as a season alone cannot define a precise beginning or end. Instead of estimating months, refer to production records and match the detail to your sources.
Which summary most accurately reflects Garzón’s materials?
Do not replace the stated range or midpoint with the product’s actual measured value. Summarizing this material means retaining the description “3–6 months.”
Can the phrase 'aged on lees' be used to estimate the frequency of stirring?
Contact with the lees and the stirring action known as bâtonnage are separate pieces of information. Even if the contact period is listed, you still need to confirm whether stirring was performed and how often it occurred.
Basis and sources for the exercise
Practice exercises in comparison
Based on these two wines, can you conclude that 'longer lees contact results in greater richness'?
Read examples of organizing comparisons
| Conditions for Comparison | Lumière Koshu Sur Lie 2024 | Garzón Albariño Reserva 2023 |
|---|---|---|
| Raw material | Kōshū from Yamanashi Prefecture. | Albariño from Uruguay. |
| Lees contact | Explanation: no racking until spring. | The technical sheet states lees contact and aging for 3–6 months. |
| Accuracy of information | Do not infer exact months just from 'spring' as a seasonal notation. | Do not replace a range of periods with a fixed number of months. |
| Condition to check separately | Handling of skins, container, and stirring frequency are described separately from lees. | Separate fermentation vessels and aging on lees, do not assume lees stirring if not mentioned. |
| Limitations of comparison | Do not attribute taste differences solely to sediment, since both the variety and the vintage are different. | Treat as a comparison to learn their common processes. |

Explain in your own words
Write a 200–400 character introduction for the two bottles, including shared processes, conditions that cannot yet be compared, and what you want to confirm through tasting.
Check after writing
- Are you arbitrarily converting seasonal descriptions into specific numbers of months?
- Are you confusing contact with the lees and stirring?
- Have differences in variety and year been retained?
Reorganize using the comparison table
A comparison table listing processes and conditions lets you check for any missing explanations.
