Skin Contact (Orange Wine) — Method and Flavour Profiles

Orange wine is white wine made like red wine — with extended skin contact. The result is one of the most unusual and polarising wine styles: amber to deep copper in colour, grippy with tannin, complex with oxidative and dried-fruit characters that no conventional white wine can produce.

What Is Orange Wine?

The term "orange wine" describes a white or rosé grape variety fermented or macerated on its skins for an extended period. The colour comes from anthocyanins (pigments) in the skins — even white grape skins contain small amounts, which extract into a golden-amber colour over time.

Skin-contact wines exist on a spectrum:

• A few hours: barely perceptible phenolic grip, slight depth of colour — "skin-contact rosé" territory
• 2–7 days: distinct golden colour, noticeable tannin, dried fruit and honey notes
• 2–4 weeks: full amber colour, significant grip, complex oxidative character
• Several months: deep orange/amber, very high tannin, pronounced oxidative/nuts/dried fruit — traditional Georgian qvevri style

History and Geography

Skin-contact winemaking is one of the oldest techniques in the world. The traditional Georgian qvevri method — whole-bunch fermented in buried clay amphorae with months or years of skin contact — dates back thousands of years.

Current production centres:

• Georgia (Kakheti): traditional amber wine in qvevri — the origin
• Friuli-Venezia Giulia (Italy): Josko Gravner, Radikon — the wine world's reintroduction to the style in the 1990s
• Brda (Slovenia): similar tradition to Friuli
• Alsace, Austria, Australia, South Africa: growing natural wine movement producers

Which Grapes Work Best

Not all white varieties respond equally to skin contact.

Thin-skinned varieties (e.g. Pinot Blanc) produce less colour and tannin; thick-skinned varieties (Pinot Grigio, Gewurztraminer) produce more.

Equipment and Vessel Choice

The traditional Georgian method uses qvevri (buried clay amphorae), which provide:

• Micro-oxygenation through porous clay
• Very stable temperature (buried in earth)
• Mild reductive then oxidative character

For home winemakers:

• Open-top plastic fermenter: simple and effective for first trials
• Glass carboy with wide-mouth: allows punch-down access
• Stainless tank: controllable, easy to clean

Avoid vessels you can't fully access for punch-downs.

Making Your First Orange Wine

Harvest targets

Pick slightly earlier than for conventional white wine — you want higher acidity to balance the tannin you're about to extract. pH 3.1–3.4, TA 7–9 g/L.

Pre-ferment SO₂

Keep low if you want wild fermentation. For controlled skin contact, add 20–30 mg/L free SO₂ and inoculate with commercial yeast.

Whole-bunch or crushed?

• Whole bunch in the vessel: Carbonic maceration develops naturally, producing aromatic complexity. Bunches later crushed by the weight above them.
• Crushed and destemmed: More conventional; more surface area; faster tannin extraction. Remove stems unless fully lignified.

Temperature during maceration

• Cold maceration (8–12°C, pre-ferment): Slower extraction, more delicate tannin. 3–7 days common.
• Warm fermentation (18–22°C): More vigorous extraction, more structure.

Cap management

Exactly like red wine pigeage — push the skin cap down 2–3 times daily. White grape skins form a more fragile cap than red varieties.

How long to macerate?

Taste the wine daily. Tannins should be detectable but not harsh. For first attempts, stop maceration when:

• Colour is the amber/orange shade you desire
• Tannins are present but velvety (not harsh or drying)
• Aromatics are still present under the phenolic layer

For a first attempt, 5–10 days is a safe range. Longer maceration is a more advanced technique.

Pressing

Press gently. Skin-contact wines are typically pressed to free-run + P1 only; heavy press fractions will be too harsh.

Post-press handling

Contrary to conventional white winemaking, skin-contact wines are often:

• Racked with some lees present (oxidative protection, complexity)
• Aged with minimal SO₂ additions (deliberate oxidative character)
• Not filtered or fined (preserving natural texture)

That said, higher SO₂ and filtration produce cleaner, more stable orange wines — a valid commercial choice.

Flavour Profile

A well-made orange wine is unlike any other category:

• Aromatics: Dried apricot, marmalade, chamomile, beeswax, mushroom, dried flowers, nuts
• Palate: Tannic grip, full body, texturally more like a red wine than a white
• Acidity: Present but often less prominent than conventional white
• Finish: Long, savoury, sometimes slightly oxidative
• Faults (to avoid): Excessive VA (vinegar), excessive brett (barnyard), or excessive oxidation (flat, brown, "old sherry" character without fruit)

Common First-Time Mistakes

Using under-ripe stems: Adds harsh, green tannin. Destem or confirm stem lignification.

Insufficient acidity: Without enough acid, the tannin overwhelms the palate. Pick earlier or acidify.

Poor sanitation: Wild acetobacter on unwashed skins converts alcohol to acetic acid. Sanitise all equipment; optionally add low-dose SO₂ to the must pre-ferment.

Tasting too rarely: Without regular tasting, you can't judge when to press. Taste daily from day 3.
