How is orange wine made? Skin maceration explained
An orange wine starts exactly like a white wine: with white grapes harvested by hand. What changes everything is what happens next. Instead of pressing the grapes immediately to separate the juice from the skins, the two are left in contact — sometimes for a few days, sometimes for several months. It is this contact time between the juice and the skins that transforms an ordinary white into an orange wine.
Step 1: the harvest — impeccable or nothing
Everything starts in the vineyard. Skin maceration is a technique that amplifies everything — qualities as well as flaws. A damaged grape, a skin contaminated by fungus, and the entire wine can be spoiled. That is why orange wine producers almost systematically work with organic or natural viticulture, using manual harvesting and rigorous sorting in both the vineyard and the winery.
To fully understand the importance of manual harvesting, our article on manual vs. mechanical harvesting explains why this choice is decisive.
Step 2: gentle crushing (or whole clusters)
The grapes arrive at the winery in whole clusters. The winemaker can choose two approaches:
- Whole clusters in the vat: the clusters are added without destemming or crushing. Maceration begins gently, with fermentation starting inside the berries. This technique produces lighter and fruitier wines.
- Destemming and gentle crushing: the stems are removed, and the berries are pressed slightly to release some of the juice, then everything — juice, skins, and seeds — goes into the vat together. This technique extracts more structure and tannins.
In both cases, no filtration or immediate pressing occurs — this is precisely what distinguishes orange winemaking from classic white winemaking.
Step 3: maceration — the heart of the process
This is where everything happens. The white grape juice is in direct contact with the skins (and sometimes the seeds). During this time, two phenomena occur simultaneously:
- Alcoholic fermentation: indigenous yeasts present on the skins convert sugars into alcohol. In natural wine, this fermentation is spontaneous — no selected yeasts are added. It is slower and produces more complex aromatic profiles.
- Extraction of compounds from the skins: pigments (which provide the color), tannins (which provide the structure), and potential aromas (which provide complexity) gradually migrate from the solid to the liquid. The longer the maceration, the greater the extraction.
The duration of maceration varies greatly depending on the style desired by the winemaker:
- 2 to 7 days: short maceration. The wine remains close to a white, slightly amber, with barely perceptible tannins. This is often the most accessible format for those new to orange wine.
- 1 to 4 weeks: medium maceration. The color is distinctly orange, tannins are present, and the aromas are complex and dense.
- 3 months to 1 year: long maceration, in the Georgian style. The wine is a deep amber, tannic, with aromas of nuts, beeswax, and spices. It is the most challenging style for a palate accustomed to classic whites — and often the most fascinating.
Step 4: the container — amphora, vat, wood
The choice of container during maceration profoundly influences the final wine. Georgian-style orange wines ferment and macerate in qvevri — terracotta amphorae buried in the ground, which maintain a cool and constant temperature. In Europe, natural winemakers use a variety of containers:
- Terracotta amphora: the closest to tradition. Slight porosity, gentle micro-oxygenation, excellent thermal regulation.
- Stainless steel vat: neutral, hygienic, allows for precise temperature control. Produces fresher and fruitier wines.
- Old wood (demi-muids, used barrels): provides slight micro-oxygenation that rounds out the tannins without imparting woody flavors.
- Concrete (vat or egg): inert, good thermal regulation, increasingly used for orange wines.
To learn more about the containers used in natural winemaking, our article natural winemaking, from vat to BIB details the choices made by each winemaker.
Step 5: pressing and aging
Once maceration is complete, the winemaker gently presses the pomace (the skins and seeds) to extract the remaining juice. This juice joins the "free-run" juice (which flowed naturally during maceration). The whole mixture is then aged — for a few months to several years depending on the style — before being put into a BIB or bottle.
In natural winemaking, aging is done without fining or coarse filtration. The wine may remain slightly cloudy — this is normal and has no impact on quality. The slight cloudiness of an orange wine is not a flaw: it is often the signature of an unfiltered wine, and thus more expressive.
What is the difference compared to a white, a red, and a rosé?
The difference lies entirely in the duration of contact with the skins:
- Classic white: white grapes pressed immediately, zero contact with skins.
- Saignée rosé: red grapes with a few hours of contact with the red skins — just enough to slightly tint the juice.
- Red: red grapes with several days to weeks of maceration on red skins.
- Orange: white grapes with several days to several months of maceration on white skins.
This is why one can view orange wine as the "white counterpart" to red wine: same logic of extraction, same potential tannic richness, but starting from a white grape.
Frequently asked questions about making orange wines
Can you make an orange wine with any white grape variety?
Technically yes, but some varieties are much better suited than others. Varieties with thick skins and rich aromatic potential (Pinot Gris, Gewurztraminer, Muscat, Chenin, Savagnin) yield the best results. A Chardonnay or Sauvignon Blanc with thin skins can produce an interesting orange wine, but one that is less intense. The aromatic richness of the skins is the main factor.
Does skin maceration damage the wine?
Not if the grapes are healthy and the winemaker is vigilant. Maceration amplifies everything: if the grape is good, the wine will be better than a classic white made from the same grape. If the grape is dubious, the maceration will amplify the flaws. It is a technique that leaves no room for error — which explains why quality orange wines always come from winemakers who are very rigorous about their raw material.
Does orange wine contain more alcohol than a white wine?
Not necessarily. The alcohol level depends on the sugar level in the grape at harvest, not the duration of maceration. An orange wine produced with grapes harvested at normal ripeness will have a similar alcohol level to a white from the same variety and the same region — often between 12 and 13.5%.
