La normativa de la Unión Europea sobre vinos ecológicos se aplica a todos los tipos de vino, incluidos los espumosos como el Cava, el Prosecco y el Champán. La base de la regulación es la misma que para los vinos tranquilos, pero se aplican algunas consideraciones adicionales específicas de la producción de espumosos.

Here are the key points:

1. Organic agriculture and viticulture:

• 100% organic grapes: The wine must be made exclusively with grapes grown according to the principles of organic farming.
• Prohibition of synthetic chemicals: The use of synthetic chemical pesticides, herbicides, fungicides, and fertilizers is not permitted.
• Focus on biodiversity: Organic winegrowers promote soil health and a balanced vineyard ecosystem by encouraging biodiversity to strengthen the vines' natural resilience. Natural fertilizers, such as compost and manure, are used.
• Non-GMO: Genetically modified organisms (GMOs) are not allowed anywhere in the process.
• Vineyard management: Soil health and biodiversity are prioritized, using natural methods to control pests and diseases.

2. Production in the winery:

• Sparkling wine production methods: Organic regulations adapt to the different sparkling wine production methods, such as the traditional method (Cava and Champagne) and the Charmat method (Prosecco).
• Additives and Processes: The use of certain additives and oenological techniques is restricted. For example, in organic wines, the use of organic yeasts is preferred, and the use of some clarification products is prohibited or limited.
• Licours of expedition and tirage: In the case of sparkling wines, the addition of sugars and must is permitted, but these must come from organic farming for the wine to be certified as such. The liqueur of expedition (added before the final cork) and the liqueur of tirage (for the second fermentation) must meet organic criteria.

3. Sulfite limits:

• Sulfite limits are stricter for organic sparkling wines than for their conventional counterparts. In general, organic sparkling wines have a lower maximum sulfite limit than conventional ones.
• In the EU, organic white and rosé wines have a limit of 155 mg/l for dry wines with a residual sugar level above 2 g/l (compared to 205 mg/l for conventional wines). It's important to note that these limits are general and can vary depending on the type of sparkling wine and the sugar level, but the main rule is that the permitted levels for organic wines are always lower.

Un caso especial: La Denominación de Origen Cava

La D.O. Cava ha ido un paso más allá de la normativa de la UE. Ha establecido un reglamento que exige que todos los Cavas de la categoría “Guarda Superior” (incluyendo los Cavas Reserva, Gran Reserva y de Paraje Calificado) sean elaborados con uvas procedentes de viñedos 100% ecológicos. Esta normativa entró en vigor con la vendimia de 2025, convirtiendo a la D.O. Cava en un referente mundial en la producción de espumosos ecológicos de alta calidad.

In short, sparkling wines like Cava, Prosecco, and Champagne can be certified organic as long as they comply with strict EU regulations, which apply not only to agriculture but also to winemaking practices and the limited use of sulfites. The Cava D.O. has reinforced this commitment with its own internal regulations.
