Skin Contact White Wine / Orange Wine

Skin contact white wine, commonly called orange or amber wine, is produced by fermenting white grapes with their skins, seeds, and sometimes stems left in contact with the juice, mimicking the process normally reserved for red wine. In conventional white winemaking, the skins are removed immediately after crushing. Keeping them in contact allows the wine to extract color pigments, phenols, and tannins that produce a spectrum of color ranging from pale gold with brief maceration to deep copper or amber after months of contact. The style goes by several names: 'orange wine' in the broader wine trade, 'amber wine' in Georgia, and 'ramato' in Italian, a term historically applied to skin-contact Pinot Grigio from Friuli-Venezia Giulia.

• The International Organisation of Vine and Wine officially describes orange and amber wine as 'white wine with maceration,' distinguishing it clearly from both conventional white and red wine
• Color intensity correlates directly with maceration duration; the longer the skin contact, the darker the resulting wine's amber or copper hue
• Unlike red wines, where tannins are expected, the grippy, drying texture of skin-contact whites is a deliberate stylistic departure from conventional white winemaking

During fermentation, alcohol acts as a solvent, extracting phenolic compounds from grape skins, including tannins, color pigments, and flavonoids that are absent in conventionally pressed white wine. The winemaker can adjust the character of the wine by controlling how long the skins remain in contact, at what temperature fermentation occurs, and how much the cap of skins is stirred or punched down. In the traditional Georgian Kakhetian method, crushed grapes including skins, seeds, and sometimes stems are poured into a buried qvevri, stirred daily during fermentation, then sealed and left to macerate through the winter before being drawn off in spring. In Friuli, producers like Radikon ferment in large Slavonian oak vessels with macerations lasting from weeks to several months, while Gravner uses qvevri from Georgia, fermenting white wines for approximately ten months before aging in large oak casks.

• Qvevri are buried underground to maintain stable temperatures throughout fermentation, providing natural temperature regulation without mechanical cooling
• Radikon's flagship blue-label wines undergo two to four months of maceration in oak vats, followed by four years of maturation in large oak barrels before bottling without fining or filtration
• Gravner's white wines spend approximately ten months fermenting in buried qvevri, then age for several more years in large Slavonian oak casks before release

Skin contact reorients a white wine's sensory profile from fresh and floral to structured, savory, and complex. Aromatically, extended maceration typically reduces delicate citrus and primary floral notes while amplifying dried fruit, spice, and oxidative characters such as dried apricot, hazelnut, honey, and tea leaf. The most distinctive sensory feature is tannic texture; skin-contact whites develop a drying grip on the palate that is normally associated with light red wines, giving them unusual body and weight. Aged examples develop further complexity, with tertiary notes of dried fruits, nuts, and subtle oxidative depth emerging over years in bottle. Saša Radikon has noted that some of the estate's wines can age more than twenty years, with acidity softening and classic tertiary flavors developing over time.

• Tannins from white grape skins are typically softer than those in red grapes, but months-long maceration can produce wines with a texture genuinely comparable to light reds
• Ribolla Gialla, with its thick, flavoursome skins, is particularly well suited to extended skin contact and is the signature variety in Oslavia and the Collio hills of Friuli
• The combination of tannic grip and retained acidity makes skin-contact whites exceptionally versatile at the table, pairing successfully with a wider range of dishes than either conventional whites or reds

The origins of skin-contact white wine lie in Georgia, where archaeological evidence from the Kvemo Kartli region dates winemaking to around 6000 BCE. The qvevri method, in which white grapes ferment on their skins in buried clay vessels, has been practiced continuously in Georgia and has never been fully abandoned, even during the Soviet period when traditional practices were heavily suppressed. The modern international revival began in the 1990s in Italy's Friuli-Venezia Giulia, particularly in the village of Oslavia near the Slovenian border. Stanko Radikon returned to long maceration in 1995, reviving techniques his grandfather had used, while Josko Gravner committed to skin-contact wines from the 1997 harvest and traveled to Georgia in 2000, subsequently adopting qvevri for all his white wines from the 2001 vintage. Their neighbour Dario Princic was also among the early pioneers of the Oslavia cluster. The term 'orange wine' was coined in 2004 by British importer David Harvey of Raeburn Fine Wines, giving the category a commercially useful name that accelerated its global spread.

• Georgian qvevri winemaking was added to UNESCO's Intangible Cultural Heritage list in 2013, recognising the tradition's deep cultural roots
• Kakheti in eastern Georgia is the heartland of amber wine production, accounting for around three-quarters of the country's total wine output
• The Imeretian method, practised in western Georgia, uses only a small portion of the grape solids rather than the full Kakhetian method, producing a lighter, less tannic style of amber wine

Josko Gravner of Friuli-Venezia Giulia is widely regarded as the most influential contemporary figure in orange winemaking. Farming 15 hectares of organically certified vineyards across Italy and Slovenia, Gravner ferments his Ribolla Gialla in buried Georgian qvevri, followed by years of aging in large Slavonian oak casks; wines are typically released seven to ten or more years after harvest. Radikon, now led by Stanko's son Saša following Stanko's death in 2016, produces Oslavje (a blend of Chardonnay and Sauvignon Blanc) and the 'S range' wines including Slatnik, with annual production of around 65,000 bottles distributed to more than twenty countries. In Georgia, Pheasant's Tears, founded in 2007 by American artist John Wurdeman and Georgian winemaker Gela Patalishvili in Sighnaghi, Kakheti, has become one of the most influential natural wine producers in the country, fermenting indigenous varieties including Rkatsiteli and Mtsvane in qvevri with macerations ranging from three weeks to six months.

• Gravner converted fully to qvevri fermentation for all white wines from the 2001 vintage, after importing the first qvevri from Georgia following a visit there in 2000
• Radikon's flagship blue-label range, including Ribolla Gialla, Oslavje, and Jakot, is bottled without added sulfur and released only after several years of aging
• Pheasant's Tears was founded in 2007 by John Wurdeman and Gela Patalishvili and works with over 17 hectares across several Georgian regions, preserving indigenous varieties including rare cultivars nearly lost during the Soviet era

Extended skin contact introduces complexities that require careful management. As alcohol rises during fermentation, it extracts increasing quantities of phenolics and potassium from the skins; the latter can raise pH and shift tartrate equilibrium, requiring attentive acidity monitoring. Oxidative exposure during maceration needs to be managed to achieve the desired level of intentional oxidative development without tipping into spoilage. Many skin-contact producers use little or no added sulfur, relying on tannin extraction itself to provide natural stability: Radikon found that extended maceration naturally preserved his wines without sulfur additions, stopping additions entirely for most of his wines. Most serious producers ferment with native yeasts and avoid temperature control and fining, resulting in wines that may be cloudy or show sediment but are considered by their makers to be more expressive of grape and place.

• Radikon stopped adding sulfur with the 2002 vintage, relying on extended skin contact and tannin content for natural preservation
• Native yeast fermentation is standard practice among most serious orange wine producers, with Saša Radikon describing authentic orange wine as requiring wild yeast fermentation without temperature control
• Wines with months-long macerations are often bottled without fining or filtration, meaning visible sediment or cloudiness is normal and expected
