My mother recently died and among the items she left behind is a Green bottle (filled with some kind of wine(?) with the following words inscribed:

Vielle Reerve
MIS EN BOUTEILLE AU DOMAINE
Domaine
Le Leahitte
Bas Armagqnac
APPELLATION ARMAGNAC CONTROLEE

750 ml
80 Proof
PROPRIETAIRE RCOLTANT A
MAULEON D'ARMAGNAC (GERS)

This has never been opened and I've no idea what this is. Could you please help me or direct me to someone who can?

Thank you.

Marilyn
