La Casera

La Casera is a traditional Spanish brand of soda. It is one of the most popular soft drinks in Spain. It is a sweet fizzy drink known in Spain as gaseosa. It can be served as a regular soda, although it is also customary to mix it with wine, receiving the name of Tinto de Verano, or beer, called a Clara or Rubia. La Casera may also be used to prepare sangria. 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. From that moment on, his life was connected to Spain.
