This mini has been kicking around the back of a shelf for years, so @slkinsey and I busted it open last night.
We did get the sense that whatever it began as had oxidized somewhat: there was not much citrus present in the nose or taste, and we sensed some sherry-like characteristics. Plenty of alcohol was present—the bottle said 70 proof, and I doubt it was any lower than that. It’s hard to say exactly what it tasted like. Prune brandy liqueur? That makes it sound worse and more specific than it was, though. Also interesting is that it was a drier liqueur than we expected—more triple sec than curaçao, and perhaps even less sweetness than that.
We wrung two miniature cocktails out of the sample: a Gift of the Gods (equal parts dry gin, dry vermouth and Forbidden Fruit) from Tarling, and the Tantalus Cocktail (equal parts Forbidden Fruit, brandy and lemon juice) from McElhone. The former was more the successful drink, and it even unraveled a bit more citrus character from the liqueur, but alas, there was overall nothing to get excited about, here. Oh well.
