The recipe has traditionally been guarded by 'dolotières' — women over forty initiated into the Sandogo secret society — who pass the exact brewing method down only through that initiation.
Sorghum or millet is soaked, germinated, sun-dried, ground and slow-boiled for hours into a tangy, low-alcohol beer, then served warm or cool from large calabashes. It's brewed and sold by women in dedicated 'tchapalodromes' across northern towns like Ferkessédougou near Korhogo.
