Andrew Quady’s change of career from making fireworks to making wine produced an explosion of its own kind when he created Essensia from the Orange Muscat grape. It was an instant success and until 1985 he could not make enough to satisfy demand. Now Quady is the foremost American winery specialising entirely in dessert wines and continues to win medals worldwide. In 1975 winery’s first port-like wine was made from Amador County Zinfandel. Now it is made from traditional Portuguese varietals such as Tinta Roriz and Tinta Cao.
