## Amber Wine

### Introduction

**Amber wine** is a style of **white wine produced with extended skin contact**, where white grapes ferment together with their skins, seeds, and sometimes stems. This technique extracts **phenolics, tannins, pigments, and aromatic compounds**, resulting in wines with a **deep amber to copper color and a tannic structure similar to red wine**.

Although now produced globally, the tradition is most strongly associated with the ancient winemaking culture of Georgia, where such wines have been made for thousands of years in underground clay vessels called Qvevri.

The term **“orange wine”** is often used synonymously in modern wine markets, but **“amber wine”** is the more historically neutral and technically descriptive term.

---

# Technical Definition

**Amber wine:**

*A white wine produced by fermenting white grape varieties with prolonged contact between the grape juice and solid parts of the grape (skins, seeds, occasionally stems), resulting in significant extraction of phenolic compounds, tannins, and pigments that impart an amber to copper coloration.*

---

# Production Method

### 1. Harvest

White grape varieties are harvested at **full physiological ripeness**.

Common grapes include:

* Rkatsiteli

* Mtsvane

* Ribolla Gialla

* Pinot Grigio

* Malvasia Istriana

---

### 2. Crushing

Grapes are crushed to release the must while retaining skins and seeds.

---

### 3. Skin Fermentation

Fermentation occurs with the skins.

Contact duration may range from:

| Contact time | Result |

| -------------- | ------------------------------- |

| 3–7 days | light amber |

| 2–4 weeks | structured amber wine |

| several months | deeply tannic traditional wines |

Traditional Georgian wines may remain on skins **for 6 months**.

## Georgian Amber Wine

### Introduction

**Georgian amber wine** is a traditional wine style produced in Georgia by fermenting **white grapes with prolonged skin contact**, usually in buried clay vessels known as Qvevri.

This method represents one of the **oldest continuously practiced winemaking traditions in the world**, with archaeological evidence of viticulture in Georgia dating back **about 8,000 years**.

In Georgian terminology, these wines are typically called **“white wines made in Qvevri”**, but internationally they are widely referred to as **amber wine** or **orange wine** due to their deep color.

The traditional **Qvevri winemaking method** is recognized by UNESCO as **Intangible Cultural Heritage**.

---

# Technical Definition

**Georgian amber wine**:

*A white wine produced from native Georgian grape varieties fermented and macerated with skins, seeds, and often stems in buried clay vessels (qvevri), resulting in wines with amber coloration, significant tannin structure, and complex oxidative-reductive aromatic development.*

---

# Key Grape Varieties

Traditional Georgian amber wines are usually produced from indigenous grapes:

| Variety | Characteristics |

| ---------- | ----------------------- |

| Rkatsiteli | high acidity, structure |

| Mtsvane | floral aromatics |

| Kisi | aromatic complexity |

| Khikhvi | ripe fruit and spice |

| Chinuri | balanced acidity |

| Tsolikouri | softer structure |

---

# Qvevri Production Method

## 1. Crushing

Whole clusters are crushed and placed into **Qvevri**.

Unlike most white wines, the mixture contains:

* juice

* skins

* seeds

* often stems.

---

## 2. Fermentation

Fermentation occurs **naturally with indigenous yeasts**.

The thick cap of skins rises to the top and is periodically punched down.

---

## 3. Extended Maceration

Traditional maceration duration:

| Duration | Result |

| ---------- | --------------------------- |

| 1–2 months | lighter amber wines |

| 4–6 months | classic Georgian amber wine |

Many wines remain on skins **through winter until spring**.

---

## 4. Natural Clarification

After fermentation:

* solids settle to the bottom

* wine clarifies naturally without filtration.

---

## 5. Aging

Wines may continue aging in:

* **qvevri**

* oak barrels

* neutral vessels.

Total maturation often lasts **6–18 months**.

---

# Chemical Characteristics

| Parameter | Typical Range |

| -------------- | ------------------------ |

| Alcohol | 12–14% |

| Residual sugar | dry |

| Total acidity | 5–7 g/L |

| Phenolics | very high for white wine |

| Tannins | moderate to strong |

The high tannin level comes from **extended extraction from skins and seeds**.

---

# Sensory Profile

### Appearance

* deep golden

* amber

* copper

### Aromas

Typical aromas include:

* dried apricot

* orange peel

* tea

* honey

* nuts

* herbs

* resin

| ------------------- | ------------------- | ------------------ |

| Fermentation vessel | Qvevri | tanks / amphora |

| Maceration time | very long | variable |

| Tradition | ancient | modern revival |

| Tannin level | high | moderate |

---

# Cultural Importance

Amber wines are deeply embedded in Georgian culture and cuisine.

Traditional wine cellars called **marani** contain buried **Qvevri**.

The technique represents one of the **earliest forms of controlled fermentation in human history**.

---

✅ **Key identity of Georgian amber wine:**

*A tannic skin-fermented white wine produced in buried clay qvevri using indigenous Georgian grape varieties.*

---

If you want, I can also provide a **complete atlas of Georgian amber wine styles by region (15–20 traditional styles)** including:

* Kakhetian method

* Imeretian method

* Kartlian method

* Gurian method

which is extremely useful for a **global oxidative / skin-contact wine classification system**.

================================================

You are right to question that. **Qvevri wine** from Georgia should **appear in a global atlas of oxidative-related wine styles**, but the reason it is sometimes omitted is **classification ambiguity**.

Qvevri wines are **not primarily defined by oxidation**, but by **vessel type and fermentation method**. However, many of them show **mild to moderate oxidative characteristics**, especially the traditional amber wines.

---

# 1. What Qvevri Wines Are

A **qvevri** is a large clay amphora buried underground used for fermentation, maceration, and aging.

Qvevri

Typical process:

1. Whole grapes (often with stems)

2. Long skin maceration (3–6 months)

3. Fermentation and aging in buried clay vessel

4. Minimal intervention

This technique is recognized by:

* UNESCO

as **Intangible Cultural Heritage of Humanity**.

---

# 2. Oxidation Level in Qvevri Wines

| Style | Oxidative Level |

| ------------------ | -------------------- |

| Sherry / Madeira | strong oxidation |

| Vin Jaune | controlled oxidative |

| Qvevri amber wines | mild oxidative |

The oxidation occurs because:

* clay is **slightly oxygen permeable**

* vessels are **not perfectly airtight**

* long maceration increases phenolic oxidation

However, the goal is **structure and extraction**, not oxidation.

---

# 3. Georgian Amber Wines (Closest to Oxidative Style)

The wines most relevant to oxidative classification are:

| Wine style | Grapes |

| ----------------------- | ---------- |

| Amber qvevri wines | Rkatsiteli |

| Kakheti qvevri wines | Kisi |

| Traditional amber wines | Mtsvane |

These wines develop:

* amber color

* dried fruit aromas

* tea / walnut notes

* tannic structure

But unlike **Vin Jaune** or **Oloroso Sherry**, oxidation is **not the primary winemaking goal**.

---

# 4. Why They Are Often Classified Separately

Most wine classification systems place qvevri wines in:

**Traditional Vessel Fermentation Wines**

rather than:

**Oxidative Wines**

because their defining factors are:

| Primary factor | Qvevri wine |

| -------------- | ---------------------- |

| Vessel | clay amphora |

| Maceration | very long skin contact |

| Fermentation | with solids |

| Oxidation | secondary effect |

---

# 5. Correct Position in a Global Wine Atlas

A more accurate classification is:

### Oxidative / Oxygen-Influenced Wines

**Strong oxidative wines**

* Madeira wine

* Oloroso Sherry

**Moderate oxidative wines**

* Vin Jaune

**Oxygen-permeable vessel wines**

* Qvevri wine

---

# 6. Important Distinction

Oxidative flavor in qvevri wines usually comes from:

* **polyphenol extraction**

* **polymerization of tannins**

* **slow oxygen ingress through clay**

not from **deliberate oxygen exposure** as in Sherry or Vin Jaune.

---

✅ **Conclusion**

Georgian qvevri wines are **not excluded because they lack oxidation**, but because:

* their **classification is vessel-based rather than oxidation-based**

* oxidation is **secondary rather than intentional**

However, in a **complete global atlas**, they should definitely appear as:

**oxygen-permeable amphora wines**.

---

If you want, I can also show a **much deeper classification of oxidative and oxygen-influenced wines (≈70 styles worldwide)** including:

* amphora wines

* sous-voile wines

* rancio wines

* solera wines

* heated wines

This taxonomy is used in **advanced wine atlas systems and wine databases**.
