Cul Sec Rouge en Voiture: A Wine Proxy Done Right

Straight to it: Cul Sec Rouge en Voiture isn’t trying to be wine. If you want wine, drink wine. What Dutch producers Fruitslagers have made is something else. A fermented proxy that borrows wine techniques but refuses the imitation game. When I poured this bottle and stopped looking for Pinot Noir, the drink started to work. The friends of Grote Hamersma agree, awarding it 9.5.

What is a wine proxy

Rouge en Voiture is one of four bottles in Cul Sec’s 2025 cuvée, all under 0.5 percent alcohol. They sit in conversation with wine rather than imitating it. Compare it to kombucha: it uses fermentation but doesn’t claim to be beer. Cul Sec uses wine grapes, terroir thinking, oak aging and fermentation techniques, but builds something categorically distinct.

The Domaine Cul Sec philosophy centres on “building an estate full of wilderness and regeneration.” Flavours come from the landscape. Oyster shells for minerality, various woods for tannins, lacto-fermented fruits for depth. Winemaking’s toolbox applied to a different project. The name Rouge en Voiture, “Red on the Go,” sums up the idea: serious without pretence, complex without being precious.

Borrowed technique, original vision

Fruitslagers spent a year working with European farmers, sourcing organic Pinot Noir and Kékfrankos from Nemesgulács in Hungary, plus Dornfelder from Kitzingen in Germany. Instead of fermenting them into wine, they build a base from ripe oxidised grapes and tart verjus. High acidity, plenty of tannin, no alcohol.

The alchemy comes through lacto-fermentation, the same bacterial process behind kimchi and sauerkraut. Rhubarb and red currant go through that transformation, developing complex flavours without added sugar. The liquid ages on oak with kombucha cultures, then gets infused with blackcurrant leaf using hydrosonic extraction. High-frequency sound waves pull intense flavour in minutes rather than weeks. Kelp adds mineral depth. Terroir thinking applied to wild fermentation. Place and process build character, not pretending grape juice can taste like Burgundy.

Tasting notes

Once poured, the colour hits first. Intense, almost impenetrable garnet with subtle effervescence. Significantly darker than the 2024 I tasted last year with Fleur from Fruitslagers.

The nose jumps out of the glass. Beets and dark cherry as the base, chestnut and hazelnut for nutty depth. Fresh herbs (basil, oregano, stinging nettle) push it toward savoury. Earthy undergrowth and bramble leaf underneath. Fruity, but in a wild, foraged way rather than the sweetness of fruit juice. Expect conventional wine aromatics and you’ll be disappointed. Stay open and you stay hooked.

On the palate, the structure surprises. Real tannins, grippy mouthfeel. Bright, mouth-watering acidity. The beet notes come back with earthiness. A pleasant bitterness on the finish, plus abundant fruit and herbs in the close. The gentle sparkle adds lift without going aggressive. Slightly less cold than fridge temperature opens the aromatics better.

When and how to drink it

No hangover, even if you finish the 750 ml bottle. Under 0.5 percent alcohol is functionally zero.

It works best when you’re not trying to replace wine. At lunch when you want something serious but need to stay sharp for the afternoon. For anyone avoiding alcohol who misses the sophisticated end.

For pairing, autumn dishes come to mind. A wild mushroom risotto finished with shaved truffle. The earthy, umami-rich flavours mirror the drink’s character. It also works with roasted root vegetables, aged cheeses, and dark chocolate.

Don’t serve this when someone asks for “something like a nice Chianti.” That’s setting everyone up for disappointment. It doesn’t resemble wine, and that’s the point. Serve it to someone curious about fermentation or after something with character. Once opened, drink within five days as the freshness fades.

Honest assessment

Rouge en Voiture succeeds at what it sets out to do. A complex, terroir-driven fermented drink using wine techniques, without the alcohol. Not a soft drink in disguise. Something new. A proxy with a point of view.

The limitations are real. Availability is tight. Production is small-scale and distribution mostly runs through Roze Bunker in the Netherlands. Even if you’re intrigued, finding a bottle outside the Benelux is hard. Under €18 per 750 ml is fair for the craft, but not supermarket pricing.

The funky, earthy character won’t suit everyone. This is for natural wine drinkers, fermentation nerds, the sober-curious, and anyone who appreciates drinks with strong points of view. Not for those after something familiar or broadly crowd-pleasing.

Worth seeking out

What Fruitslagers have done with Rouge en Voiture earns attention. A wine proxy that stands on its own merits. Not just a good alcohol-free alternative to natural wine; a superb alcohol-free drink full stop.

If you’re curious about applying wine philosophy to build something genuinely new, put it on your list. If you want a bottle that tastes like last summer’s Côtes du Rhône, look elsewhere. Rouge en Voiture isn’t replacing anything. It’s offering something that holds its own. Santé.
