Verjuice (Verjus)
What it is
The pressed juice of unripe (green) grapes — a tart, pale-green or rosé liquid that is sour but gentler and less harsh than vinegar or lemon. The name is French vert jus, "green juice."
How it's made
Unripe grapes (often from vineyard thinning) are pressed and the juice bottled, sometimes lightly preserved. Because the grapes are picked before sugar develops, the juice is high in tartaric and malic acid but soft, with no fermentation and no acetic sharpness.
Flavor profile
Crisp, fruity, mildly sour with a clean grape character — acidic without the harsh bite of vinegar or the aggressive citrus of lemon. Subtle and food-friendly.
Culinary uses
A medieval European souring staple, used to deglaze pans, build vinaigrettes, poach fruit, and finish sauces where wine or vinegar would be too harsh — especially useful with wine, since its gentle acidity doesn't clash. It is the secret to balancing dishes delicately. In classic French and revived modern cooking, it occupies a niche nothing else fills: acid without aggression.
Regional variations
Historically central to French and Persian (ab-ghureh, sour grape juice) cooking; nearly lost in the West, then revived notably in Australia (championed by Maggie Beer in the Barossa) and among modern chefs. Persian ab-ghureh is the same idea used in Iranian stews and soups.
Cultural & historical context
Before lemons were widely available in northern Europe, verjuice was the everyday acid of the medieval kitchen, appearing constantly in period cookbooks. Its modern revival is part of a broader rediscovery of pre-industrial flavors.
