It might be safe to say that we can use the term "Sparkling valley" or "ruta del espumante", when talking about Casablanca.
The Casablanca valley now produces a vast amount of sparkling wine and its growing as a trend in the region.
Vina Mar
Indomita
Morande
Casas del Bosque
Quintay
OC wines
Bodegas RE
Vina las Nubes
Catrala
Vina Casablanca
Over 8 vineyards are producing sparkling wine with traditional methods. Vina Mar the first vineyard to produce sparkling in the valley, used to produce with the Charmat method in Casablanca, but not any longer.
It has been a surprise that this phenomenon had not happened sooner, since the raw ingredients for sparkling,
being Chardonnay and Pinot Noir, have always grown in abundance under the cool climate of the Casablanca valley.
So any sparkling wine fans would do well to venture to Casablanca to sample the sparkling wine buzz.
