Bandji has to be drunk within hours of tapping — left overnight, it keeps fermenting on its own and turns noticeably more sour and alcoholic by the next morning.
Sap tapped straight from oil or raphia palms is collected in gourds and drunk fresh, still faintly sweet, lightly fizzy and only mildly alcoholic. Tappers sell it by the roadside in villages around San-Pédro's palm forests, often within hours of collection.
