Basque cider is an apple cider from the Basque region of Europe served at sagardotegi (cider houses). Known as Sagardoa, the cider in Basque cuisine is produced at cider houses in areas such as Astigarraga, Spain, an apple growing region. It is sold in bottles, is flat (non-carbonated), and poured from height. Salted cod omelette is a traditional dish eaten in Basque cider houses. Quince jelly and nuts are also served as well as steak.
