Basque cider, also known as sagardoa, is a traditional alcoholic beverage that is popular in San Sebastian and the surrounding Basque Country. It is made from fermented apple juice and has a slightly tart and fizzy taste. Basque cider is typically poured from a height to create bubbles and release its natural carbonation. It is often enjoyed alongside a traditional Basque cider house meal, which includes dishes like salt cod omelette, grilled steak, and Idiazabal cheese. The cider houses in San Sebastian offer a unique dining experience where visitors can taste the local cider and indulge in delicious Basque cuisine.
