Castoro Cellars is located in Paso Robles California’s thriving central coast grape growing region. Niels and Berit (Bimmer) Udsen began Castoro Cellars in 1983. In a span of a dozen years, the Udsen’s business grew from making a few barrels of wine for family and friends in a rented corner of a local winery to developing a notable commercial custom-crush operation and a 20,000-case, award-winning winery of their own. 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. After graduation he went to work with Tom Myers at Estrella River Winery. Niels' long-time nickname "Beaver”, evolved further when he was in Italy, his friends soon took to calling him "Il Castoro”, which is beaver in Italian. The name stuck, and since the beginning, Castoro Cellars' wines have pictured a beaver on each label. Castoro Cellars has also had the same expert production team since 1990. Veteran winemaker Tom Myers and assistant winemaker Mikel Olsten are key players in the hundreds of awards Castoro Cellar wines have earned over the years.
