Cava, Spain’s answer to Champagne, is a sparkling wine that has captured the hearts of wine enthusiasts around the world. Known for its vibrant bubbles, crisp acidity, and complex flavors, Cava is a versatile and celebratory drink that can elevate any occasion. But what goes into making this delightful sparkling wine? In this article, we will delve into the intricate process of how Cava wine is made, from the vineyard to the bottle, exploring the traditional methods, key ingredients, and regional characteristics that make Cava unique.
The Origins of Cava
A Brief History
Cava has its roots in the Penedès region of Catalonia, Spain, where it was first produced in the late 19th century. The story of Cava begins with Josep Raventós, a winemaker from the Codorníu winery, who was inspired by the Champagne-making techniques he observed during a visit to France. Upon his return, Raventós adapted these methods to local Spanish grapes, creating a sparkling wine that would eventually become known as Cava.
The Name “Cava”
The term “Cava” originally referred to the caves or cellars where the wine was aged. In 1970, the name was officially adopted to distinguish Spanish sparkling wines made using the traditional method from those produced elsewhere. Today, Cava is protected by a Denomination of Origin (DO) status, ensuring that only wines produced in specific regions and adhering to strict regulations can bear the name.
The Grapes of Cava
Traditional Varieties
Cava is typically made from a blend of three traditional grape varieties: Macabeo, Parellada, and Xarel·lo. Each grape contributes unique characteristics to the final wine:
Macabeo: Also known as Viura, Macabeo is the most widely planted grape in Cava production. It provides fresh, floral aromas and a light, crisp acidity.
Parellada: This grape adds finesse and elegance to the blend, with delicate floral and citrus notes. It is often used to enhance the wine’s aromatic complexity.
Xarel·lo: Known for its robust structure and high acidity, Xarel·lo contributes body and depth to the wine, along with hints of apple and pear.
Other Permitted Varieties
In addition to the traditional trio, other grape varieties such as Chardonnay, Pinot Noir, and Subirat Parent (Malvasía) are also permitted in Cava production. These grapes can add additional layers of flavor and complexity, allowing winemakers to create a diverse range of styles.
The Traditional Method: Méthode Champenoise
Cava is made using the traditional method, also known as the “Méthode Champenoise,” which involves a secondary fermentation in the bottle. This labor-intensive process is what gives Cava its signature bubbles and complex flavors. Here is a step-by-step breakdown of how Cava is made:
1. Harvesting and Pressing
The journey of Cava begins in the vineyard, where the grapes are carefully harvested by hand to ensure optimal ripeness and quality. Once harvested, the grapes are quickly transported to the winery to preserve their freshness.
The grapes are then gently pressed to extract the juice, which is known as the “must.” The pressing process is crucial, as it determines the quality and character of the base wine. For Cava, only the first press, or “free-run juice,” is typically used, as it is the purest and most delicate.
2. Primary Fermentation
The must is transferred to stainless steel tanks or oak barrels for the primary fermentation. During this stage, yeast converts the natural sugars in the grape juice into alcohol, producing a still base wine. The primary fermentation typically lasts for about two to three weeks, depending on the desired style and characteristics of the wine.
3. Blending
After the primary fermentation, the base wines are carefully blended to create the desired flavor profile. This is a critical step in Cava production, as the blend determines the final character and complexity of the wine. Winemakers may blend wines from different grape varieties, vineyards, or vintages to achieve the perfect balance of acidity, body, and aroma.
4. Secondary Fermentation
The blended wine is then bottled, and a mixture of sugar and yeast, known as the “liqueur de tirage,” is added to initiate the secondary fermentation. The bottles are sealed with a crown cap, and the wine undergoes a second fermentation in the bottle. This process produces carbon dioxide, which dissolves into the wine, creating the bubbles that Cava is known for.
The secondary fermentation typically lasts for several weeks, during which the yeast cells consume the added sugar and produce alcohol and carbon dioxide. As the yeast cells die, they form a sediment known as “lees,” which contributes to the wine’s complexity and texture.
5. Aging on Lees
After the secondary fermentation, the bottles are stored horizontally in cool, dark cellars for an extended period of aging on the lees. This aging process, known as “sur lie,” is a key factor in developing the wine’s flavor and aroma profile. The minimum aging period for Cava is nine months, but many producers age their wines for much longer to achieve greater complexity and depth.
During this time, the yeast cells break down and release compounds that contribute to the wine’s bready, toasty, and nutty characteristics. The length of aging on the lees can vary depending on the style of Cava being produced:
Cava Joven: Aged for a minimum of nine months, this style is fresh and fruity, with vibrant acidity and lively bubbles.
Cava Reserva: Aged for a minimum of 15 months, this style offers greater complexity and depth, with notes of toast, nuts, and baked apple.
Cava Gran Reserva: Aged for a minimum of 30 months, this style is rich and sophisticated, with pronounced autolytic flavors and a creamy texture.
6. Riddling (Remuage)
After aging, the bottles undergo a process called “riddling” or “remuage,” which involves gradually tilting and rotating the bottles to collect the yeast sediment in the neck. Traditionally, this was done by hand, with skilled workers turning each bottle a small amount each day. Today, many producers use automated riddling machines to achieve the same result more efficiently.
7. Disgorging (Dégorgement)
Once the yeast sediment has been collected in the neck of the bottle, the wine is ready for disgorging. The neck of the bottle is frozen, and the crown cap is removed, allowing the frozen sediment to be expelled by the pressure of the carbon dioxide. This process leaves the wine clear and free of sediment.
8. Dosage
After disgorging, a small amount of wine and sugar, known as the “liqueur d’expédition” or “dosage,” is added to the bottle to adjust the sweetness level and balance the acidity. The amount of sugar added determines the final style of the Cava:
Brut Nature: No added sugar, with less than 3 grams of residual sugar per liter. This style is bone-dry and crisp.
Extra Brut: Very low sugar, with 0-6 grams of residual sugar per liter. This style is dry and refreshing.
Brut: Low sugar, with 6-12 grams of residual sugar per liter. This is the most common style, offering a balance of dryness and fruitiness.
Extra Seco: Slightly sweeter, with 12-17 grams of residual sugar per liter. This style is off-dry and approachable.
Seco: Medium sweetness, with 17-32 grams of residual sugar per liter. This style is semi-sweet and fruity.
Semi-Seco: Sweet, with 32-50 grams of residual sugar per liter. This style is rich and dessert-like.
Dulce: Very sweet, with more than 50 grams of residual sugar per liter. This style is luscious and dessert-worthy.
9. Corking and Finishing
After the dosage is added, the bottle is sealed with a cork and wire cage to secure the pressure. The final step involves labeling and packaging the wine, ready for distribution and enjoyment.
