[1] The origin of the company dates back to Francisco Duffo Foix, born in Saint-Laurent-de-Neste, France, in 1873.
On a trip to San Sebastián, Spain, he met his future wife, Victoria González, with whom he eventually had five children.

In Spain, the popularity of the product has led to the use of its name to refer to any citrus soda, regardless of the brand.
