Alvanian brandy
Alvanian brandy is an alcoholic beverage typically housed in pyramidal-shaped, glass bottles.
Sometime prior to stardate 49930.3, Doctor Bashir of Deep Space 9 received a case of Alvanian brandy as payment from a patient which he donated to Quark's Place. Bashir insisted that the brandy wasn't charity for Quark, as he found the stuff "undrinkable". (DS9: "Body Parts")
