Neither white nor red, ‘blouge’ is carving out a place for itself in wineries. Behind its playful portmanteau name lies a revived co-fermentation technique that has emerged as a response to climate challenges and a new-found thirst for light wines.

The revival of an age-old practice
The name may sound thoroughly modern, but the technique itself is centuries-old. By fermenting white and red grapes in the same tank, ‘blouge’ harks back to a time – long before ampelography made its mark – when winegrowers cultivated mixed vineyard plantings. Known as field blends, they combined multiple grape varieties from the same crop. Once used to soften the structure of certain wines in regions such as Rioja and Tuscany, the practice all but disappeared from European vineyards, save for a few enduring exceptions like Côte-Rôtie. In the northern Rhone Valley appellation, Syrah may still be co-fermented with a small proportion of Viognier, a long-established practice enshrined in the appellation’s production rules since the AOC was created in 1940. Today, Viognier may account for up to 20% of the blend.
Co-fermentation: fusion in the tank
The term ‘blouge’, though neither official nor regulated, can refer to several winemaking techniques, even if co-fermentation of red and white grapes remains the most widespread. While the practice itself is far from new, it is now being deployed with greater intent to craft distinctive wine styles. Unlike blends assembled after vinification, co-fermentation allows skins, sugars, acids and yeast to interact from the very start of fermentation. The resultant wines display unique characters which are difficult to replicate in any other way. Adding white grapes can amplify the floral and fresh fruit notes, refine the tannins and stabilise the colour.
A response to climate change
For many winegrowers, blouge also offers a pragmatic response to climate change. That was certainly the thinking for Alexia Piaï, winemaker at Château Guilhem (Aude), when she ventured into blouge territory with a Merlot and Sauvignon Blanc blend from the 2024 vintage. “People occasionally refer to the benefits of adding white varieties to reds to counterbalance a lack of acidity. This was not our primary motivation”, she explains. “Our main goal was to lower alcohol content. In Languedoc, some red wines can easily reach 14% ABV. By incorporating a white grape variety, we can produce a wine at 11.5% ABV, which is a real advantage”.
The challenge of ripeness
In the glass, the wine shows a light crimson hue with aromas of morello cherry and raspberry, lifted by a fresh finish. Reaching that point, however, requires a delicate balancing act at harvest: “You have to find the right compromise between two grape varieties that do not ripen at the same pace,” explains Piaï. “The Sauvignon needs to be ripe enough while still retaining acidity, whereas the Merlot cannot be picked too green”. Once this hurdle has been overcome, the winemaking process follows classic procedures: “Very light skin contact in the press, quick pressing to achieve the desired colour, followed by white wine fermentation techniques”.
Vins De France: a creative playground
By venturing into uncharted territory, blouge often falls under the Vin De France category. At Wine Paris 2026, Valérie Pajotin, director of Anivin*, pointed to the growth of a category that offers winegrowers “a space free from rigid regulations, allowing them to experiment with styles that were previously out of reach”. Château Guilhem shares that interpretation: “The framework allows us to create wines that would not be permitted under AOP or IGP rules, without confusing customers who are more mindful of the tasting experience than of the label”. Blouge has also begun carving out a place for itself in export markets, although the estate’s Malepère appellation wines remain its primary touchstone.
New tasting vocabulary
In Bordeaux, Marie Olivier, sommelier at the wine shop and eatery Echo, has a front-row seat to this shape-shifting category: “A blouge can be extremely interesting… or not. But some of them can be genuinely exciting from a stylistic perspective”. She sees clear parallels with orange wines: “In much the same way, the balance in these hybrid wines creates an interplay between the structure of red wine and the freshness of white, opening up new avenues to explore in terms of food and wine pairings.” When featured on wine lists, the term sparks curiosity and often calls for explanation. “Some knowledgeable customers make an informed choice, but most are driven by curiosity. The consumer profiles are actually very diverse, ranging from groups of friends to couples and people in their thirties”, she observes.
Alexia Piaï believes that the discovery element provides an interesting lever. “This is a style that particularly appeals to consumers who are less familiar with red wines, while also opening up niche markets”.
Culinary curiosity
Even so, the wines remain oddballs that defy standardisation: “Liking one blouge doesn’t mean you’ll like them all. A blend of Gamay and Chardonnay from Auvergne bears no resemblance to a Bordeaux Cabernet-Sémillon pairing”, stresses Marie Olivier. Beyond these contrasting features, the wines – many with a predominance of red grapes – can evoke structured, even profound rosés that will effortlessly grace a table: “Delicately-flavoured fish or white meats – vitello tonnato for example – make a particularly good match”. Blouge transcends passing fashions and marketing ploys, truly epitomising an industry that has the ability to reinvent itself. Combining structure with lightness, these wines seem destined to carve out a place as pleasure-driven styles offering immediacy and accessibility. They are also a reminder that, in wine as in life, the most serendipitous encounters are often the most rewarding.
