Produttori del Barbaresco: Comparing two vineyards from the same year
A cooperative established in 1958 by growers in Piemonte, Italy. They vinify only Nebbiolo from members’ vineyards and produce Barbaresco and single-vineyard Riservas.
Comparing Asili and Rabajà Riserva 2021 using official sources. We check the shared steps and organize the vineyard-specific points.
Questions for this course
If two bottles share the same variety, vintage and production method, can you isolate the effect of soil alone?
Before you start reading, briefly jot down your thoughts. You will rephrase them at the end.

Asili and Rabajà, 2021
The two Produttori del Barbaresco Riservas compared are 2021, 100% Nebbiolo. Asili and Rabajà are geographic names recorded in the MGA section of the technical documentation. These samples are aligned by producer, grape variety, harvest year, and Riserva category.
Common vinification conditions in the documentation
Both technical documents note fermentation temperature of 30°C, 28 days of skin contact, and completion of malolactic fermentation. Maturation is 30 months in large barrels and 9 months in bottle, with bottling taking place in May 2025. Instead of assuming the same process just from the label, cross-check the technical data for each vintage.
Area and slope orientation
The Asili data states 2.28ha, south to southwest facing; Rabajà is 3.7ha, southwest facing. These areas are from the specific wine’s source data, not the total area of each MGA. Separate the boundaries of the name and the actual plot where fruit is grown.
Multiple factors contribute to differences between vineyards.
Even with many shared winemaking conditions, orientation, vine condition, and harvest decisions are not always the same. Even if tasting differences are observed in this comparison, they cannot be attributed solely to soil. After confirming the matched conditions in the documentation, list any additional information you wish to know about the vineyard.
What to align and what to compare.
Starting Point for Comparison
- Conditions to standardize
- Producer • 100% Nebbiolo • 2021
- Conditions for comparison.
- Asili and Rabajà
- Additional points to confirm
- The vineyard name is MGA, and the indicated area refers to the vineyard in question according to the given data.
Winemaking validation
- Conditions to standardize
- 30℃, 28 days skin contact
- Conditions for comparison.
- According to the material, process conditions are identical.
- Additional points to confirm
- Also confirm cultivation and harvest conditions that are not noted.
Comparison of locations
- Conditions to standardize
- Barbaresco Riserva
- Conditions for comparison.
- Orientation, parcel, and cultivation conditions
- Additional points to confirm
- Are you attributing differences in taste only to the soil?

Produttori del Barbaresco: Interpreting documentation—a comparison of two vineyards from the same year
Check for differing conditions by reading the table and sources. For tastings, list characteristics not included in the data separately as aspects to confirm.
This is a summary of materials published by the producer. Vintage-specific information comes from material for that year; details without a vintage refer to the product or process description at the time checked.
| Comparison items | Asili 2021 | Rabajà 2021 |
|---|---|---|
| Grapes | 100% Nebbiolo | 100% Nebbiolo |
| Vineyard area and exposure in the source material | 2.28ha, facing south to southwest | 3.7ha · southwest |
| Fermentation and skin contact | 30℃・28 days | 30℃・28 days |
| Aging | 30 months in large casks, 9 months in bottle | 30 months in large casks, 9 months in bottle |

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 are the conditions common to both wines?
The producer and the year 2021, with 100% Nebbiolo; the vinification conditions listed in the table are consistent. This does not mean, however, that the vineyards Agli and Rabajà are identical.
How should the area of 2.28ha be interpreted?
You need to keep track of the subject as you read the source material. If a figure is used to describe the overall MGA area or a producer’s total vineyard holdings, you may confuse different scopes.
Can the difference in taste be conclusively explained only by soil effects?
Choosing the same year, grape variety, and producer makes comparison conditions clear, but vineyard differences involve multiple factors. Explain while noting any conditions that remain unverified.

| Conditions for Comparison | Asili 2021 | Rabajà 2021 |
|---|---|---|
| Grapes | 100% Nebbiolo | 100% Nebbiolo |
| Vineyard area and exposure in the source material | 2.28ha, facing south to southwest | 3.7ha · southwest |

Sources of materials used for comparison are listed in the text and exercises.
Explain in your own words
List at least three conditions that are consistent between these two wines, explain why the flavor difference cannot be attributed to soil alone, and describe additional vineyard information to check.
Check after writing
- Did you match the two materials from the same year?
- Did you limit the described vineyard area range?
- Be wary of reducing vineyard differences to a single cause.
