Sparkling wine from terroir to table

Sparkling Wine Production Process

Sparkling wine gets its bubbles through a secondary fermentation process, which can occur in bottles or large tanks. There are several main production methods:

Traditional Method (Méthode Traditionnelle, Champenoise)

This method is used for producing Champagne, Cava, and many other high-quality sparkling wines. The process includes the following stages:

1. Primary fermentation – Producing base wine with high acidity. Grape varieties like Chardonnay, Pinot Noir, or Pinot Meunier are used.
2. Blending – Mixing different wines to achieve the desired style.
3. Tirage liqueur – A mixture of yeast and sugar is added to initiate secondary fermentation.
4. Secondary fermentation in the bottle – Natural carbon dioxide forms and dissolves in the wine, creating bubbles.
5. Aging on the lees – The aging duration affects the flavor (minimum 15 months for Champagne, 9 months for Cava).
6. Riddling (turning the bottles) – The sediment gradually moves to the neck of the bottle.
7. Disgorgement (removing the sediment) – The bottle neck is frozen, opened, and the sediment is expelled.
8. Dosage liqueur addition – Determines the wine’s sweetness level.
9. Corking and aging – The wine develops its final flavor before being sold.

Charmat Method (Tank Method, Cuve Close)

This method is used for producing Prosecco, Asti, and other lighter sparkling wines.

1. Primary fermentation – The base wine is produced.
2. Yeast and sugar addition – Secondary fermentation starts in large sealed tanks (autoclaves).
3. Controlled fermentation – Pressure is maintained to retain carbon dioxide.
4. Filtration and cooling – Fermentation is stopped by cooling, and the wine is filtered from sediment.
5. Bottling under pressure – Bottling occurs without losing carbonation.

Advantages: Faster production, preservation of fresh fruit flavors. Disadvantages: Less complex flavor and texture.

Ancestral Method (Méthode Ancestrale)

The oldest method used to produce Pet-Nat and other natural sparkling wines.

1. Fermentation in tanks – The wine partially ferments and is then bottled before fermentation is complete.
2. Natural completion of fermentation – The fermentation continues in a sealed bottle, naturally producing bubbles.
3. No riddling or disgorgement – The wine remains with sediment, creating a more “raw” and natural taste.

This method is often used for organic and biodynamic wines.

Sparkling Wine Aging

Aging duration significantly impacts the wine’s character:

• Non-Vintage (NV) – 12-15 months, has a fresh, light taste.
• Vintage (Millésimé) – 3-5 years, develops more complex aromas.
• Prestige Cuvée – 5+ years, becomes richer, revealing notes of pastry, nuts, and honey.

The longer the aging on the lees, the creamier the texture and the more complex the bouquet.

Sparkling Wine Tasting

To assess the quality of sparkling wine, consider the following aspects:

• Serving temperature: 6-10°C.
• Glassware: Tulip-shaped or flute glasses to preserve aroma.
• Aroma: Fruits, flowers, honey, nuts, yeasty notes.
• Taste: Balance of acidity, sweetness, and bubble texture.

Food Pairings with Sparkling Wines

Sparkling wines pair wonderfully with a variety of dishes:

• Champagne – Oysters, seafood, white fish, soft cheeses.
• Prosecco – Light salads, fruits, Brie cheese, nuts.
• Asti – Desserts, fruits, delicate creamy pastries.
• Cava – Tapas, Jamón, olives, fried chicken.
• Pet-Nat – Artisanal cheeses, smoked meats, craft snacks.

How to Choose a Sparkling Wine

When selecting a sparkling wine, consider the following aspects:

• Production method – Traditional method offers more complexity, while Charmat is suited for lighter wines.
• Sugar content – From Brut Nature (dry) to Demi-Sec (sweet).
• Aging – Longer aging results in a richer taste.
• Grape variety – Chardonnay adds freshness, Pinot Noir brings berry notes.
• Region of production – Champagne, France, produces the most refined examples, whereas Prosecco is more fruit-forward.
• Purpose – Whether for an aperitif, celebrations, or food pairings.

Choosing the right sparkling wine will help you fully enjoy the experience! 🥂
