Cava

Cava is a protected Spanish sparkling wine made by the traditional method: the second fermentation occurs in the bottle, followed by a period on the yeast sediment and its removal through disgorgement. Its identity combines geographical origin, grapes, and production requirements.

The Penedès area of Catalonia is its principal historical and production centre, but the denomination includes delimited areas elsewhere in Spain. The protected name applies to wine from those defined areas.

Grapes and base wines

Macabeo, Xarel·lo, and Parellada form the familiar traditional combination. Their different growing habits and base-wine properties give producers options for blending. Chardonnay and other authorized varieties broaden the range, while red grapes including Pinot Noir, Garnacha, Monastrell, and Trepat contribute in applicable wines.

Fruit is harvested for the intended sparkling base, with attention to acidity, potential alcohol, aroma, and sound skins. Pressing, clarification, and the first fermentation establish much of the wine before bubbles are created. Producers may keep varieties, vineyards, and press fractions apart to assess the lots before blending.

A pale base wine can come from dark-skinned grapes if pressing limits pigment extraction. Rosé production follows its own permitted practices.

Second fermentation and maturation

At tirage, the base wine is bottled with yeast and fermentable sugar. The sealed fermentation generates carbon dioxide, which dissolves under pressure. The wine then remains with the sediment before riddling moves it toward the neck and disgorgement removes it.

Lees contact can add maturation character and modify texture. Its effects depend on the base wine, time, temperature, and yeast. A wine can retain fruit expression while developing more yeast-derived notes.

The final sweetness is another choice. Dosage and the finished wine's composition distinguish styles such as Brut Nature, Brut, and sweeter categories. A longer ageing category does not itself describe the amount of residual sugar.

Ageing categories

The specification linked by the regulatory board and consulted in October 2026 sets minimum periods from tirage to disgorgement of nine months for Cava, 18 for Reserva, 30 for Gran Reserva, and 36 for Paraje Calificado.1. Consejo Regulador de la DOP Cava, Pliego de condiciones, sections 3–4 and 7, version linked from its legislation directory on 28 October 2026. Periods run from tirage to disgorgement, not from harvest.

The current category framework groups Reserva, Gran Reserva, and Paraje Calificado under Guarda Superior. Additional conditions concern production, traceability, and category eligibility.

Geographical origin and comparison

The consulted specification names four zones: Comtats de Barcelona, Valle del Ebro, Viñedos de Almendralejo, and Requena. More focused subzones and qualified sites can supply further origin information.1.

Periods run from tirage to disgorgement, not from harvest. Their climates and vineyards add differences before the winemaker chooses a blend.

Champagne shares the bottle-fermentation method, using different grapes in a different growing environment. Most Prosecco undergoes its second fermentation in a tank, although it also has bottle-refermented traditions.
