That is an interesting smell and taste, I might give it a go at replacing the Cointreau in my long islands 🏝️ 😂 not the same orange vibes but it might be an interesting experiment

is that some kind of aguardente?

a funny thing, at least in portugal, aguardente, literally "firewater" is a normal name for almost anything from grape brandy to plum brandy to vodka to rum made from sugarcane juice, although those things usually get called "rum"
