Cava is Spain’s iconic sparkling wine, famous for its elegance, complexity, and bubbly character. With its roots deeply embedded in the heart of Catalonia, cava has evolved from a regional drink to a globally recognized wine with a rich history and a distinct winemaking method. While many are familiar with sparkling wines like Champagne, cava offers its own unique appeal. But how exactly is cava made? In this article, we will explore the intricate process of cava production, highlighting each step in detail, from vineyard to bottle.
Introduction to Cava: Spain’s Sparkling Treasure
Cava is a sparkling wine produced primarily in the Penedès region of Catalonia, Spain. Unlike other sparkling wines, cava has an interesting production process that combines traditional methods with the influence of the local terroir. The wine is made using the traditional “Método Tradicional,” the same process used for Champagne, though cava tends to have a different taste profile due to variations in climate, grape varieties, and regional practices.
Cava is typically made from three grape varieties: Macabeo, Xarel·lo, and Parellada. However, other grape varieties such as Chardonnay and Pinot Noir are also used in cava production, contributing to its diverse range of styles.
But how does cava go from grape to glass? In the following sections, we will guide you through every stage of cava production.
From Vineyard to Harvest: Growing Grapes for Cava
The journey of cava begins in the vineyard. The quality of the grapes used in the production of cava is paramount, as they are the foundation of the wine’s flavor, acidity, and overall character. The first step in creating cava is ensuring that the vineyard conditions are ideal for the production of quality sparkling wine grapes.
The Terroir of Cava
Cava is most commonly associated with the Penedès region, which enjoys a Mediterranean climate with cool breezes from the nearby Mediterranean Sea. The combination of warm days and cool nights provides the perfect environment for grape varieties like Macabeo, Xarel·lo, and Parellada to thrive.
The region is home to diverse soil types, including clay, limestone, and sand, all of which influence the flavor profile of the wine. Soil rich in limestone imparts a mineral quality to the grapes, while clay-based soils contribute to the freshness and acidity in the wine.
Choosing the Right Grapes
The three primary grape varieties used in cava production are:
- Macabeo (Viura): A neutral white grape variety that contributes freshness and lightness to cava. It is known for its floral and citrus aromas.
- Xarel·lo: A more aromatic variety that adds structure, acidity, and depth to the wine. Xarel·lo is often considered the backbone of cava.
- Parellada: A delicate variety that brings elegance, floral notes, and a subtle fruity character to the wine.
In addition to these traditional varieties, some cava producers experiment with international grape varieties like Chardonnay and Pinot Noir to create unique and innovative blends.
The Harvesting Process
Harvesting grapes for cava is done by hand, a labor-intensive process that ensures only the best grapes make it into the production process. The timing of the harvest is critical in sparkling wine production, as the grapes must be picked while they still have high acidity and low sugar levels.
The grapes are typically harvested early in the morning to prevent oxidation, ensuring the grapes remain fresh and crisp. After harvesting, the grapes are transported to the winery where they begin their transformation into cava.
The Winemaking Process: Turning Grapes into Wine
Once the grapes are harvested, the next step in making cava is the vinification process, which involves transforming the fresh grapes into base wines ready for sparkling wine production.
Pressing the Grapes
The first step in vinification is pressing the grapes to extract their juice. In cava production, the pressing must be done gently to avoid extracting bitter compounds from the grape skins. The process is typically carried out using pneumatic presses, which apply soft pressure to the grapes to release the juice without damaging the delicate skins.
The juice extracted from the first press, known as the “free run” juice, is considered the best quality and is used to make cava. The juice is then separated into different fractions, with the first press being the most sought after for producing high-quality sparkling wines.
Fermentation
The next step in the process is fermentation. The grape juice is placed in fermentation tanks, where yeast is added to convert the sugars in the juice into alcohol. During the first fermentation, the juice undergoes primary fermentation, resulting in a base wine. This base wine is the foundation for cava and has relatively low alcohol content and high acidity, which is crucial for creating a balanced sparkling wine.
Fermentation typically lasts for about 15 days, and temperature control is key to ensuring that the yeast ferments the wine slowly and steadily, preserving the freshness and aromatic characteristics of the grapes.
Blending the Base Wines
After fermentation, the wine is tasted, and different base wines are blended to achieve the desired style and profile for the cava. This is where the winemaker’s expertise comes into play, as blending can be an art form. The winemaker will combine wines from different grape varieties and vineyards to create the perfect balance of acidity, fruitiness, and complexity.
In many cases, some base wines are aged for a short period before blending to enhance their flavor and texture. The final blend is typically stored in stainless steel tanks to preserve its freshness before moving on to the next stage.
The Secondary Fermentation: Creating the Bubbles
One of the key elements that sets cava apart from other wines is its secondary fermentation. This process is what creates the signature bubbles that make cava so enjoyable to drink. But how does this process work?
Bottling the Base Wine
The base wine is bottled with a mixture of sugar and yeast, which kick-starts the secondary fermentation process. This mixture, known as the “liqueur de tirage,” is added to the wine in each bottle before it is sealed with a crown cap.
The wine is then placed in horizontal racks in cool, dark cellars to undergo fermentation a second time. This fermentation takes place inside the bottle, creating carbon dioxide gas that is trapped, resulting in the characteristic bubbles of cava. This is known as the “Méthode Tradicional” or “Traditional Method.”
Aging on Lees
Once fermentation begins, the wine undergoes a process called “aging on lees,” where it is left in contact with the dead yeast cells (lees) for an extended period of time. This aging process is essential for developing the complexity and richness of cava.
During this time, the wine takes on additional flavors and textures from the lees, including notes of bread, biscuit, and toasted nuts. The length of aging on the lees varies depending on the style of cava being produced, with premium cavas typically undergoing longer aging periods of 12 months or more.
Riddling (Remuage)
To remove the yeast sediment from the bottle, cava producers use a process called “riddling” or “remuage.” This involves gradually rotating the bottles to move the sediment toward the neck of the bottle. The bottles are placed in special racks, known as “pupitres,” and slowly turned by hand or machine over a period of weeks.
Riddling helps clarify the wine and ensures that the bubbles remain fine and persistent. The process is crucial for maintaining the purity and elegance of the final product.
The Final Touches: Disgorging and Bottling
Once the aging and riddling are complete, the final steps in the production process are the disgorging and bottling of the cava.
Disgorging
After the sediment has been moved to the neck of the bottle, it is time to remove it. This process, called disgorging, involves freezing the neck of the bottle and ejecting the frozen plug of yeast sediment.
Disgorging is typically done by dipping the neck of the bottle into a freezing solution to create a frozen plug of sediment. The bottle is then quickly opened, and the pressure inside the bottle forces the plug out. This process leaves the wine clear and free from any remaining yeast particles.
Dosage
At this stage, the cava may be topped off with a small amount of wine or sugar, known as the “dosage.” This step is used to adjust the sweetness level of the cava and to ensure that the wine has the desired balance of acidity and fruitiness.
The amount of sugar added during the dosage determines the style of cava, from the driest “Brut Nature” to the sweeter “Demi-Sec.” Once the dosage is added, the bottle is sealed with a cork and wire cage.
Bottling and Labeling
The final step is bottling the cava. After disgorging and dosage, the wine is sealed with a cork and placed in a wire cage to secure it. Bottles are then labeled and packaged for distribution.
Conclusion
The process of making cava is a meticulous and time-consuming journey, one that requires the skill and dedication of experienced winemakers. From the careful selection of grapes to the delicate art of secondary fermentation, each stage of cava production is essential in creating the signature bubbles, complexity, and refreshing acidity that make cava so special.
While cava shares some similarities with Champagne, it is distinct in its own right, offering a taste of Spain’s rich winemaking heritage. The combination of traditional methods, local grape varieties, and the unique terroir of the Penedès region ensures that every bottle of cava is a true reflection of its origins.
Next time you open a bottle of cava, take a moment to appreciate the craftsmanship and the centuries of tradition that went into its creation. Whether you’re enjoying it with a meal or celebrating a special occasion, cava is a wine that speaks to the heart of Spanish winemaking and the artistry of sparkling wine production.
