Castoro Cellars

The husband and wife team of Niels and Bimmer Udsen estab­lished Castoro Cellars   in 1983 with the goal of producing worldclass wines from Paso Robles appellation   grapes. Niels, born and raised in Ventura, California, got started in the   Paso Robles wine business while studying Agribusiness at California   Polytechnic University, San Luis Obispo. Eventually, his love of production   and wines led him and Bimmer to establish their own winery in the area.


Castoro Cellars has grown to what it is today by a series of events that Niels and   Bimmer Udsen call the ​‘backwards approach.’ The Udsen’s first made and sold   the wine, then purchased their own equipment, the winery, the tasting room,   and then began purchasing and planting vineyards.

Castoro’s   tasting room is in Templeton off scenic High­way 46 West and the wine­making   facility is located on the East Side of Paso Robles in San Miguel. Both   facilities opened in 1990.


With the help of Niels’ mentor and Castoro Cellar’s winemaker, Tom Myers, the Udsen’s have gone from making a few barrels of wine for family and friends in a rented corner of someone else’s winery to developing a custom crush operation and a 30 – 40k case enterprise for Castoro Cellars.


The creation of Castoro Cellars has been an organic process for Niels and Bimmer Udsen. Both view wine as an integral part of the daily meal and hold strongly to the belief that quality wine should be available to all wine consumers. Both share a deep respect for the land and a desire to encourage stewardship of the environment. Thus, Niels and Bimmer have structured Castoro Cellars to reflect their values and have developed an approachable and environmentally conscious brand.


Castoro Cellars currently has over 1,400 acres of Estate vineyards, which are certified organic by CCOF and all the vineyards are SIP Certified.
