Viognier: for aromatic whites and blending in reds
We will compare the white wines of Condrieu and the red wines of Côte-Rôtie. Learn to interpret aromatic impressions, the roles of each grape variety, and actual blends, then extend your understanding to Shiraz blends in Australia.
Questions for this course
In what cases is Viognier, a white variety, also used in red wine?
Before you start reading, briefly jot down your thoughts. You will rephrase them at the end.

Aromas reminiscent of yellow peaches and apricots
Viognier is a white variety with ties to the northern Rhône. Inter Rhône introduces it as having aromas reminiscent of yellow fruit and spices, and a smooth palate. Such fruit aroma appears in dry whites as well. If the aroma seems sweet, check the apparent sweetness on the palate to avoid confusing varietal aromas with fermentation residual sugar in your records.
The terraced vineyards of Condrieu and its white wine
Condrieu is located on the right bank of the Rhône River, where narrow terraced vineyards stretch along steep granite slopes. The grape used for white wine is Viognier. Clay in weathered or cracked granite areas is involved in root extension and moisture retention. Rather than simply describing the taste as “granite,” you can understand the cultivation background better by observing the slope’s orientation, soil thickness, and water conditions.
Viognier used among reds
In Côte-Rôtie, it is permitted to blend up to 20% Viognier with Syrah. Even though the blend can include a white grape, the wine is still classified as red. However, the maximum does not mean 20% is always used. Read the producer’s blend and process information to confirm whether Viognier is used, and in what amount.

Interpreting Viognier documents: aromatic whites and blending into reds
From imaginary white and red wine production records, interpret the role and blending proportions of Viognier.
This is fictitious material created for study purposes. It does not indicate the actual blend of any existing label or the results of any appellation certification.
| Item | White A | Red B |
|---|---|---|
| Blending | 100% Viognier | 95% Syrah, 5% Viognier |
| Process | Fermentation of pressed juice. | Both varieties are put together into tank and fermented with the skins. |
| Finish | Dry white | Red |
| Maturation vessels | Not stated | Not stated |

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.
Does the inclusion of a white variety in Red B constitute a contradiction?
B is made primarily from Syrah with 5% Viognier, fermented together with the skins. The fact that a white variety is included does not mean the wine will be white or rosé overall. In fact, in Côte-Rôtie, red wines are made by combining Syrah with Viognier.
What is the proportion of Viognier in Red B?
The actual ratio shown in this document is 5%. The 20% cited in the Côte-Rôtie explanation is an upper limit and does not represent the blend for all wines. Also, you cannot judge from this sample document alone whether a specific appellation name can be used.
What can you interpret about the process of Red B?
For B, two varieties are put into the same tank and fermented together. This is distinct from combining finished wines afterwards. Since there is no note on the material of the vessel or aging, do not add inferences about new oak—just explain the steps described in the record.

| Conditions for Comparison | Condrieu | Côte-Rôtie |

Explain in your own words
Describe how Viognier is used in both wines, and explain why you can’t determine a red’s color by variety name alone.
Check after writing
- Did you distinguish white varieties and wine color?
- Did you distinguish between the provisions and the actual blend proportions?
- Did you identify the process of fermenting together?
