Isastegi Sagardo Naturala is a traditional Basque cider crafted by Isastegi Sagardotegia, located in the Basque Country of Spain. This natural cider is produced using indigenous apple varieties, primarily the sharp Errezil, sourced from local orchards.

The fermentation process employs natural yeasts in stainless steel tanks, resulting in a beverage that embodies the authentic characteristics of Basque cider. Tasting notes reveal aromas of apple skin, orchard floor, pear, and mandarin zest, offering a complex and slightly sour profile with a touch of funk.

The cider is unfiltered and unpasteurized, preserving its natural effervescence and cloudy appearance. With an alcohol content of approximately 6%, it is traditionally served chilled and poured from a height to enhance its natural carbonation.
