Every English-language guide to cava, Spain’s traditional-method sparkling wine, tells the same story: Penedès, near Barcelona, is where cava comes from, full stop. That story is incomplete. The Denominación de Origen Cava is a legal production zone that stretches across nine provinces in several regions of Spain, and two of its towns, Mendavia and Viana, sit inside Navarra itself, less than an hour from Pamplona. One of them has a winery certified to handle every stage of cava production on site, a distinction fewer than twenty wineries in the entire DO hold.
Getting this wrong is not a trivia problem. A visitor who assumes cava is strictly Catalan will never think to ask a Navarra wine shop or restaurant whether the bottle in front of them was actually grown and fermented in the region, and will miss that Navarra has its own small, certified stake in a wine most people file under “somewhere else.” It also flattens cava’s real relationship to San Fermín, which is not a week long presence like kalimotxo. It is a specific hour, and a specific, oddly guarded recipe, that most fiesta guides skip entirely.
This article draws on the official Denominación de Origen Cava regulatory board (cava.wine), the Ayuntamiento de Pamplona’s own registry of the city’s gastronomic societies, and cross checked Spanish-language reporting on Navarra’s cava producers, to lay out where cava actually comes from, how it is legally made, and the two moments it belongs to San Fermín.
From a Phylloxera Crisis to a Legal Name: How Cava Got Its Start
The traditional method (second fermentation inside the sealed bottle, the technique that gives cava its persistent, fine bubble) first produced bottles in Sant Sadurní d’Anoia, in Penedès, in 1872. The bigger turning point came fifteen years later. In 1887, phylloxera devastated Penedès vineyards, and the growers who replanted chose white varieties, primarily Macabeu, Xarel·lo, and Parellada, over the red vines they had been growing. That replanting decision is what gave cava its own identity rather than making it a sparkling red wine footnote.
The name “cava” itself did not appear in an official document until 1959, in Spain’s first legislation covering sparkling wine. The Regulatory Council of Sparkling Wines formally adopted “Cava” as the name for Spanish traditional-method sparkling wine in 1972, distinguishing it from Champagne. The legal production zone, what growers and regulators call “la Región Determinada del Cava,” was demarcated by ministerial order on February 27, 1986, and the current regulations date to 1991. In 2020, the DO Cava Regulatory Council restructured the zone into four legally defined areas: Comtats de Barcelona (where more than 95 percent of all cava is still made), Valle del Ebro, Viñedos de Almendralejo in Extremadura, and Zona de Levante around Requena in Valencia.
Navarra sits inside Valle del Ebro, the second of those four zones, alongside vineyard land in La Rioja and Álava.
The Zona de Levante zone, centered on Requena, has its own claim to fame beyond the DO label: it’s the same Valencian cava that goes into Agua de Valencia, the orange juice and cava cocktail invented in the city of Valencia in 1959.
The Two Towns Most Coverage Skips: Mendavia and Viana
Only two municipalities in Navarra fall inside the delimited DO Cava production zone: Mendavia and Viana, both in the Ribera Alta along the Ebro river. Together they account for roughly 84 hectares under vine, a small fraction of the DO’s total, but a legally real one. Two wineries anchor that production. Bodegas Mainegra operates in Mendavia. Bodegas Ondarre, founded in Viana in 1985, holds both Denominación de Origen Calificada Rioja status for its still wines and DO Cava certification for its sparkling wine, made from Viura, the same grape known as Macabeu across the border in Catalonia.
Ondarre carries the DO’s “Elaborador Integral de Cava” distinction, meaning the winery handles every stage of production (harvest, base wine fermentation, the bottle’s second fermentation, aging, and disgorgement) entirely on its own premises rather than buying in base wine or finished product from elsewhere. Only 17 of the roughly 350 wineries registered across the entire DO Cava hold that distinction. Ondarre bottles two labeled cavas, Millenium Brut and Brut Nature, and exports roughly half its production internationally. Between the two Navarra bodegas, annual output runs around 50,000 bottles each, a rounding error next to Comtats de Barcelona’s volume, but proof that “cava country” does not stop at the Catalan border. It also fits a wider pattern worth knowing before a Pamplona trip: Navarra produces far more than Garnacha, and cava is simply the least expected entry on that list.
How Cava Is Actually Made, and How the DO Says to Serve It
The traditional method is not a stylistic choice. It is the one requirement that applies everywhere inside the DO, regardless of which of the four zones the grapes were grown in: the base wine undergoes a second fermentation inside the exact bottle it will be sold in, which is what produces the fine, long lasting bead. Aging categories build from there. Cava de Guarda requires a minimum of nine months resting on its lees before release. Cava de Guarda Superior, which includes Reserva, requires at least 18 months. Gran Reserva requires at least 30. Cava de Paraje Calificado, the DO’s top tier introduced in 2015, is reserved for single, demarcated vineyard plots.
The Regulatory Board’s own serving guidance runs against the popular image of cava served in a flute at a wedding. Its official recommendation is a tulip shaped glass, narrow at the base and wider at the top, which the board says concentrates aroma better than a flute while still holding the bubble. Flutes are described as fine for emphasizing acidity and freshness; wide, coupe style glasses are explicitly discouraged because they lose carbonation fastest. Serving temperature depends on the category: Cava de Guarda, the youngest and most widely available style, is served coldest, around 8°C, to emphasize freshness, while Reserva and Gran Reserva are served slightly warmer, around 10°C, to let more of the aroma open up. Cava is not the only wine in this part of Spain with its own strict, method driven rules; txakoli follows an equally specific set of them, just a short drive north.
Cava’s One Hour in San Fermín: The Txupinazo Aperitivo
Cava is not the fiesta’s dominant drink. That role belongs to kalimotxo and beer, which take over the streets for the following nine days. But cava has a specific, narrow window at the very start of San Fermín: the aperitivo and toast that follows the txupinazo, the rocket the mayor launches from the Ayuntamiento balcony at noon on July 6 to formally open the festival. In the minutes after the rocket fires, families and cuadrillas across Pamplona open cava in the street as part of that first toast, before the week shifts decisively to kalimotxo. It is the same aperitivo instinct behind Navarra’s own hora del vermut, just compressed into a single, once a year moment instead of a daily ritual. It is a concentrated window rather than a fiesta long presence, and it is the reason cava belongs in any serious account of San Fermín’s drinking traditions even though it never becomes the week’s headline drink.
The Sorbete Sold Nine Days a Year: Gazteluleku
Cava’s second, more specific tie to San Fermín is not a generic custom but a named, verifiable institution. Sociedad Gastronómica Gazteluleku, a private gastronomic society founded in 1980 on Calle San Francisco in Pamplona’s Old Town with roughly 90 members, is registered as an active entity on the Ayuntamiento de Pamplona’s own website. Its signature product is a lemon sorbet blended with cava, served ice cold from pitchers, and sold only during the nine days of San Fermín. The recipe dates to 1991, worked out informally by a group of society members, and reporting on Gazteluleku consistently notes that the exact formula has never left the kitchen of whoever is preparing it that year. The society mixes roughly 15,000 liters of the sorbet and cava blend across the festival, and lines for it are a known feature of the week for those who know a sociedad gastronómica from the outside is not the same thing as a walk in bar. These societies are largely membership based, which is itself worth knowing before a visitor goes looking for the sorbete expecting an ordinary storefront.
For a visitor who wants a bottle for a private toast or a family table rather than the sorbete itself, both Ondarre and Mainegra produce DO certified Navarra cava, distinct from the Catalan bottles that dominate Spanish supermarket shelves nationally, and worth asking for by name in a Navarra wine shop rather than assuming cava has to come from somewhere else.
Frequently Asked Questions
Is cava only from Catalonia?
No. The Denominación de Origen Cava is a legal production zone covering roughly 160 municipalities across nine provinces in Catalonia, Aragón, La Rioja, Álava in the Basque Country, Navarra, Extremadura, and Valencia. More than 95 percent of production still comes from the Comtats de Barcelona zone in Catalonia, but Navarra has two certified municipalities of its own, Mendavia and Viana.
What is the difference between cava and champagne?
Both use the traditional method of second fermentation inside the sealed bottle, but they are legally separate designations tied to different countries and grape varieties. Cava is made primarily from Macabeu (called Viura in Navarra and Rioja), Xarel·lo, and Parellada, while Champagne is restricted to grapes grown inside France’s Champagne region, mainly Chardonnay, Pinot Noir, and Pinot Meunier.
What temperature should cava be served at?
The DO Cava Regulatory Board recommends serving Cava de Guarda, the youngest and most common style, around 8°C, and Reserva or Gran Reserva slightly warmer, around 10°C, to let more aroma develop.
Is cava served during San Fermín?
Yes, though it is not the festival’s dominant drink. Cava’s clearest moment is the aperitivo and toast that follows the txupinazo rocket at noon on July 6, and it also appears throughout the nine days in the sorbete de cava sold by the Sociedad Gastronómica Gazteluleku in Pamplona’s Old Town.
