The five stages of orange wine production
White or grey grapes are harvested, usually at full phenolic ripeness. Many orange wine producers prioritise grape health and low yields; organic or biodynamic farming is common. The grapes may be whole-cluster pressed or destemmed — whole-cluster adds stem tannins and aromatic complexity.
Varieties most used: Pinot Grigio/Gris, Gewurztraminer, Riesling, Ribolla Gialla, Rkatsiteli, Mtsvane, Malvasia.
Unlike conventional white winemaking (where skins are discarded immediately after pressing), the crushed grapes are left in contact with their skins during and after fermentation. This can range from a few days to several months — or even a year or more in traditional Georgian qvevri production. The skins contribute tannins, colour compounds (deep amber/orange) and aromatic phenols not found in skin-free whites.
Duration of maceration is the single biggest stylistic variable: 2–3 days gives a light orange wine; 6+ months gives a deeply tannic, amber wine.
Fermentation usually proceeds with wild (ambient) yeasts, often in clay vessels (amphorae, qvevri), old oak barrels or concrete. Temperature control is minimal in traditional styles. The skins cap on top of the fermenting juice and are punched down or submerged. The extended skin contact extracts colour, phenolics, tannins and compounds called furfurals — responsible for some orange wines' distinctive nutty, oxidative character.
Many producers use no added sulphur dioxide (SO₂) during fermentation; a small addition may be made at bottling.
After maceration, the wine is pressed off the skins. The free-run juice (extracted without pressing) is the finest quality. Pressed juice is rougher in tannin. Ageing is typically in neutral vessels — old oak barrels, clay, concrete or stainless steel — to avoid adding oak flavour. Some wines are aged in new oak, though this is less common in the natural-wine tradition.
Orange wines that have been aged on skins in sealed clay vessels (qvevri) for 6–12 months are sometimes called "amber wines" — the Georgian traditional category.
Orange wines are frequently bottled unfiltered and unfined — they are often cloudy or hazy in the glass. Minimal or no sulphur dioxide addition is common, meaning the wines are more fragile than conventional whites and require cool, dark storage. Some bottles may throw sediment. These are deliberate stylistic choices, not defects.
Without sulphur protection, orange wines can evolve quickly once opened. Treat them like a light red: serve slightly cool (12–14°C) rather than cold.
Georgian qvevri: the original orange wine
In Georgia, wine has been made in buried clay vessels — qvevri (also spelled kvevri) — for at least 8,000 years, making it one of the oldest continuous winemaking traditions in the world. The grapes are crushed and the juice, skins, seeds and sometimes stems are placed in the qvevri, which is then sealed with a beeswax lid and buried in the earth for 6–12 months. The earth maintains a constant cool temperature, moderating fermentation. After maceration, the wine is pressed and transferred to clean qvevri for further ageing. The resulting amber wine is tannic, complex and deeply savoury. UNESCO inscribed Georgian traditional qvevri winemaking on the Representative List of Intangible Cultural Heritage of Humanity in 2013. For how tannin in orange wine compares to red wine, see the glossary entry.
The modern revival: Gravner, Radikon and Friuli
In the 1990s, Josko Gravner of Oslavia, Friuli-Venezia Giulia, made a pivotal decision: dissatisfied with the direction of modern winemaking, he visited Georgia, was inspired by the qvevri tradition, and began importing Georgian amphorae. His skin-contact Ribolla Gialla — aged for months in buried clay — became a touchstone for a generation of winemakers. Stanko Radikon, also in Oslavia, developed a parallel but distinct approach. Their influence spread first to Slovenia (Movia, Matevc Tercic), then to natural-wine producers across France, Spain, Italy, Australia, South Africa and beyond. The style is now made in virtually every wine country, using local varieties and adapted techniques. See the South Africa wine regions guide for how Cape producers have adopted skin-contact winemaking.
