Chardonnay: reasons different whites can be produced from the same variety
From Chablis whites to Côte de Beaune, Champagne, and Franciacorta. Assess grape characteristics, and compare differences in site, vessel, lees, and bubbles.
Questions for this course
If you have two bottles both made from Chardonnay, is the taste difference due to the land?
Before you start reading, briefly jot down your thoughts. You will rephrase them at the end.

Grape variety traits and harvest-time condition
Chardonnay is a white variety that buds and ripens relatively early. In Plantgrape’s variety information, it is noted for accumulating sugar while also retaining acidity. However, this does not mean the sugar and acid levels are the same in every vineyard. You need to read them in light of site conditions and the harvest state for each year.
Barrel and lees aging are not determined by variety name alone
Chardonnay is used for both fermentation and aging in barrel, but barrel use is a choice separate from the grape’s intrinsic character. The effects of wood depend on the barrel’s age, size, and the period of contact. Whether or not to leave or stir the lees after fermentation also affects texture. Avoid generalizing “because it’s Chardonnay, it smells like oak”; separate grape and process for closer examination.
For sparkling wines, both the raw material composition and the secondary fermentation differ.
Both Champagne and Franciacorta use Chardonnay and employ secondary fermentation in bottle. However, neither only makes Chardonnay-based wines. Confirm the blends with other varieties, and compare the secondary fermentation (not found in still whites), lees ageing, and riddling processes.

Chardonnay comparison: look for comparable conditions in the materials
Even for two bottles made from the same grape variety, the necessary information varies depending on the comparison’s purpose. Separate the given data and what you inferred from it.
A, B, and C are fictional specifications for practicing comparative analysis, and do not indicate actual brands or appellation regulations.
A and B are from the same vintage, but vineyard and producer differ. The data doesn't specify sugar content, acidity, barrel size, new oak ratio, or C's lees aging period.
| Source headings | A | B | C |
|---|---|---|---|
| Grapes | 100% Chardonnay | 100% Chardonnay | Chardonnay 70%, Pinot Noir 30% |
| Type | Still white | Still white | White wines made by second fermentation in the bottle. |
| Fermentation and maturation vessels for base wine | Stainless steel tank | Oak barrel | Stainless steel tank |
| Lees contact | Available | Available | This refers to maturation after secondary fermentation. |

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.
Can the difference in taste between A and B be explained solely as an effect of barrel use?
In A and B, in addition to the vessel, both the vineyard and the producer are different. The barrel is one of the items being compared, but from the available materials, we cannot isolate the impact of the vineyard or other winemaking conditions.
What needs to be confirmed when calling the comparison of A and C a 'same variety comparison'?
C is a blend of two grape varieties. Although Chardonnay is used in both cases, the proportions and whether secondary fermentation is required differ. Even in actual Champagne or Franciacorta, do not assume 100% Chardonnay from the appellation name alone—always check the product documents for confirmation.
What can you determine from the record 'in contact with the lees'?
Contact with the lees does not mean the same as using barrels. In the data, only C shows a process after secondary fermentation. As neither the contact period nor the handling of the lees are indicated, you cannot predict if the texture will be the same.
Practice exercises in comparison
When comparing white wines from Chablis and Côte de Beaune, or Champagne and Franciacorta made from Chardonnay, list the conditions that can be controlled and those that need to be additionally confirmed for each.
Read examples of organizing comparisons
| Conditions for Comparison | Chablis / Côte de Beaune | Champagne/Franciacorta |
|---|---|---|
| Common points | Can choose a still white from Chardonnay | Can choose a product made with Chardonnay and secondary bottle fermentation |
| Vineyard confirmation | Location, aspect, block, vintage. | Origin of the raw material’s growing region and plot, and constituent harvest years |
| Winemaking confirmation | Fermentation and maturation vessels, new versus old barrels, handling of lees | Proportion of grape varieties, base wine vinification, ageing on lees, disgorgement, sugar level |
| Scope of conclusion | Even if the grape variety is the same, this is not a comparison designed solely to extract land influence. | Even if methods are the same, you cannot assume the grape composition or taste are also identical. |

Explain in your own words
For 'What kind of wine does Chardonnay make?' answer with one still and one sparkling example in 200–400 characters. Separate the variety’s traits, vineyard conditions, and producer choices, and include any information that still needs to be checked.
Check after writing
- Are you mistaking the characteristics of a variety for flavors common to all products?
- Did you indicate which step was different: barrel, lees, or secondary fermentation?
- Have you checked the producer, vintage, and blending conditions?
