The D.O. Calatayud, where it is placed Bodegas San Alejandro has its own history as a wine-growing area. To know about it we must mend to the time of the Celtiberians and speak about celtiberian city of Segeda.
Segeda is the most important celiberian city in the North of Spain. It is placed between Mara and Belmonte de Gracián at 4 km from Miedes.
In the year 2002, a winepress was found in Segeda, a sign of the existence of wine in these lands. Moreover, vessels and amphoras have been found with remains of tartrates, as well as seeds and leaves that were identified as of the Grenache variety dated in the year 153 B.C.
In the 1st century Marcus Valerius Martialis, historian born in the Roman city of Bilbilis, wrote about the great quality of the wines of the District of Calatayud, this being the first written reference about the wines of the area.
At the end of the 12th century the Cister monks founded the "Monasterio de Piedra", 50 km from Miedes, and promoted the planting of grapevines. Their cellars are a reflection of the importance of vineyards in these lands. And their spires adorned with grape leaves are another symbol of the importance of this crop.
From then until the now, wine continued to be made in this region, until, in the year 1989 Calatayud Designation of Origin appeared , with the aim of protecting and promoting the wines produced in this zone and continuing to do so in a more regulated manner.
