Ossian is also jokingly referred to as the White Aalto because Ossian is the mini-project of Javier Zaccagnini, also partner and director of Aalto in Ribera Del Duero, and Ismael Gazalo, whose family has been making wine in the region for years. The extremely old Verdejo vineyards are located in the village of 'Nieva' and are 850 meters above sea level. The vines are between 100 and 160 years old making this the longest certified vineyard in Castilla y León. On Ossian not just any Rueda is made as you will find thirteen in a dozen. No, on the contrary, Javier hired a Burgundian topoenologist. Together they vinify the small yield unique Verdejo in a Burgundian way, just like Pierre does with Chardonnay in Meursault and Puligny Montrachet. In some years a top-top cuvée is made 'Ossian Capitel'. In a few years, Ossian has grown into Spain's most revered white wine.

In 2013, Ossian was bought by José María Ruiz (from the top house Pago de Carraovejas from the Ribera del Duero) and Zaccagnini left the company. Nevertheless, the young winery remains focused on the same high quality standards and there is even more innovation and Ossian is among the absolute top of the Verdejo wines from the Rueda.
