1100 yr old Brandy

Hi there i am new to this forum (hi everone) i would like to ask anyone for their opinion on a bottle of brandy we have been given as a wedding present. We have been told that this bottle is around 100 years old?
It is an Osborne Brandy Viejo VETERANO the top of the bottle has been wax sealed and has Casa Fundada En 1772 on the label also as well as Puerto De Santa Maria. There does not seem to be any other numbers or markings on the bottle except at the bottom right hand side of the label which has Graficas Andulucia? and above it Impuesto provincial a metalico. Any information on this would be greatly appreciated.
