Cleaning a cabinet and came across some opened bottles of liquor some haven't been used in years even a decade or two. They are brandies and liquors served with desert at a dinner. The color looks good, no staining on side of bottle or separation of any kind. They are glass bottles and have been left in the dark at room temperature in cabinet for YEARS. How long will an opened bottle of liquor last?
Also are any old liquor bottles collectable?
