When cleaning the basement, two bottle of California brandy brandy were discovered hidden in the rafters. Based on the labeling declaring it illegal to give or sell to a sailor or soldier, I believe the bottles were most likely manufactured between 1917-1920. There is no other information on the labeling aside from "California Brandy" and a picture of grapes. Both bottles contain liquor and the corks are waxed and intact. Is this any good to drink or is the liquor strictly a collector's item at this point?
