The fountain with free wine exists and is located at Bodegas Irache. It is a unique attraction on the pilgrimage route of the Camino de Santiago, situated in the town of Ayegui in the Navarra region of Spain. The fountain was installed on the wall of the Bodegas Irache winery, which was founded in 1891..
The fountain is open daily from 8:00 to 20:00. There are no special restrictions regarding the use of the fountain, but it is worth remembering that the wine is mainly intended for pilgrims passing along the Camino de Santiago.
On the webpage https://www.irache.com/es/fuente-del-vino.html there is even a camera available showing the fountain live.
On the official website, you can read:
Monks welcomed pilgrims arriving at the hospital with a glass of wine. Many of them were very ill, and the wine was used as a restorative. The wine fountain at Bodegas Irache aims to remember this; in the late nineties, the fountain was formally installed, as previously wine was offered to pilgrims randomly, but after the fountain was installed, the pilgrims themselves were served as they passed by..
The fountain has two spouts, one with water and the other with wine. It is the only wine fountain that exists along the entire Camino route. Every day, the fountain is filled with about 100 litres of young red wine to quench the thirst of pilgrims and make their journey more bearable..
