Prosecco is Italy’s most important sparkling wine by volume and one of the world’s most commercially significant sparkling styles. Produced primarily in **Veneto and Friuli-Venezia Giulia**, Prosecco is defined by its use of the **Glera** grape and by its production via the Charmat–Martinotti method, which emphasizes freshness, aromatic purity, and primary fruit expression rather than autolysis.

Unlike traditional-method sparkling wines, Prosecco is designed to be immediate, fruit-forward, and approachable, with strict regulatory protection under DOC and DOCG legislation.

Prosecco is a popular Italian sparkling wine that comes from the Veneto region in northeastern Italy. The wine is primarily made from the Glera grape, although other grape varieties may be included in small amounts. Prosecco is renowned for its light and refreshing character, making it a well-loved choice for celebrations and casual enjoyment.

Key characteristics of Prosecco include its bright acidity, fruity and floral aromas, and effervescence. Unlike Champagne, which undergoes secondary fermentation in the bottle, Prosecco is typically produced using the Charmat method, where the secondary fermentation occurs in stainless steel tanks. This method helps preserve the wine's fresh and fruity flavors.

Prosecco is available in various styles, including:

1. **Prosecco DOC (Denominazione di Origine Controllata):** This is the standard classification, indicating wines produced in the delimited Prosecco region.

2. **Prosecco Superiore DOCG (Denominazione di Origine Controllata e Garantita):** This is a higher-quality designation within the Prosecco region, including specific subzones like Conegliano and Valdobbiadene.

3. **Brut, Extra Dry, and Dry:** These terms refer to the sweetness level of the Prosecco. Brut is the driest, while Extra Dry and Dry have slightly higher residual sugar levels.

Prosecco has gained international popularity due to its approachability, affordability, and versatility. It is often enjoyed as an aperitif, in cocktails like the Bellini or Aperol Spritz, and pairs well with a variety of foods. Its widespread appeal has contributed to Prosecco being a staple in the world of sparkling wines.

* Bianchetta Trevigiana

* Perera

* Glera Lunga

* International varieties (Chardonnay, Pinot Bianco, Pinot Grigio – DOC only)

---

## 3. Viticulture

### Climate

* **Moderate continental with Adriatic influence**

* Cool nights preserve acidity and aromatics

* High diurnal range in DOCG hills

### Soils

* DOC: alluvial, clay-loam, gravel

* DOCG: marl, sandstone, calcareous soils

* Cartizze: morainic, sandy-clay, well-drained

### Training Systems

* **Sylvoz** (DOC plains)

* High canopy management to protect aromatics

### Yield Limits

* DOC: up to ~18 t/ha

* DOCG: significantly lower, depending on sub-zone

* Cartizze: tightly regulated

---

## 4. Harvest Parameters

* **Harvest period:** Early–mid September

* **Typical must composition:**

* Sugar: 16–18 °Brix

* Total acidity: 5.5–7.0 g/L (tartaric)

* pH: 3.1–3.3

Harvest timing prioritizes **acid retention and aromatic freshness** over phenolic ripeness.

---

## 5. Vinification

### Primary Fermentation

* Stainless steel

* Temperature: **14–18 °C**

* Neutral yeasts to preserve varietal aroma

* Resulting base wine: 9.5–10.5% abv

### Secondary Fermentation (Charmat / Martinotti Method)

* Conducted in **sealed autoclaves**

* Duration:

* Standard Prosecco: 30–60 days

* Premium DOCG: up to 90 days

* Pressure:

* Spumante: ≥5 bar

* Frizzante: 1–2.5 bar

### Lees Contact

* Minimal to moderate

* Focus on fruit purity, not autolytic complexity

---

## 6. Styles & Residual Sugar

| Style | Pressure | Residual Sugar |

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

| **Brut Nature** | ≥5 bar | 0–3 g/L |

| **Extra Brut** | ≥5 bar | 0–6 g/L |

| **Brut** | ≥5 bar | 0–12 g/L |

| **Extra-Dry** *(traditional)* | ≥5 bar | 12–17 g/L |

| **Dry** | ≥5 bar | 17–32 g/L |

⚠️ Historically, **Extra-Dry** has been the classic Prosecco profile.

---

## 7. Alcohol Levels

* Minimum: **10.5% abv**

* Typical range: **10.5–11.5% abv**

* Cartizze often slightly higher due to ripeness

---

## 8. Sensory Profile

### Appearance

* Pale straw yellow

* Persistent, fine to medium bubbles

### Aromatics

* Green apple

* Pear

* White peach

* Citrus zest

* Acacia blossom

* Fresh herbs (occasionally)

### Palate

* Light to medium-light body

* High acidity

* Creaminess from CO₂, not lees

* Clean, refreshing finish

---

## 9. Ageing & Shelf Life

* Designed for **early consumption**

* Best within **12–24 months** of bottling

* Minimal bottle ageing potential

* Vintage rarely indicated (except select DOCG bottlings)

---

## 10. Technical Distinction vs Other Sparkling Wines

| Aspect | Prosecco | Champagne |

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

| Lees ageing | Minimal | Extensive |

| Style focus | Primary fruit | Autolysis & complexity |

| Alcohol | Lower | Higher |

---

## 11. Market & Regulatory Notes

* “**Prosecco**” is a **protected geographical indication**, not a grape name

* Glera was renamed to prevent international misuse

* Production tightly controlled by **Consorzio di Tutela**

---

### Summary

Prosecco is a **technically precise, freshness-driven sparkling wine**, whose identity relies on **Glera aromatics, controlled acidity, and Charmat fermentation** rather than complexity from ageing. At its best—especially in **Rive and Cartizze DOCG**—it combines terroir expression with commercial accessibility.
