In 1935 Brother Timothy Diener became wine master, and he served in this position for 50 years. In the 1950s they acquired Greystone Cellars near St. Helena, California. Varietal wine was made at the Napa Valley facility, generic wine and brandy were produced at Reedley in the San Joaquin Valley, and barrel aging was handled at Greystone.
