First opening its doors to the public in April 2007, the Castello di Amorosa is located near Calistoga, California. It is the pet project of 4th generation vintner, Dario Sattui who also owns and operates the V. Sattui Winery named after his great-grandfather who originally established a winery in San Francisco in 1885. Sattui claims to have spent nearly all his resources during the 14 year process of building this medieval replica castle on the vineyard grounds.
