Grogue Sugarcane Rum Distillation

Grogue (also grogu, grog); the pressing mill is called a trapiche; the extracted juice is called caldo

The pressing, wild fermentation, and pot-still distillation of fresh sugarcane juice into grogue, a high-proof rhum agricole-style spirit and Cape Verde's national drink, produced almost entirely on the island of Santo Antão (where sugarcane covers roughly three-quarters of cultivated land) and, to a lesser extent, on Santiago, São Nicolau, Maio, and Brava. Grown on steep volcanic terraces without fertilizers or pesticides, cane is hand-harvested between January and July -- mechanization being impossible on the archipelago's terraced plots -- and carried on foot to the trapiche, a traditional stone-and-wood mill historically turned by oxen or mules walking in tireless circles, though some are now electrified. The extracted juice (caldo) is pressed without any added water and ferments naturally within hours using only wild yeasts present in the air and on the cane itself, reaching roughly 15% alcohol after seven to fourteen days in open wooden vats; distillation then proceeds through small, often handmade copper or iron pot stills heated directly over an open flame fueled by dried bagasse (spent cane fiber), with a first pass yielding approximately 20% alcohol and a second pass concentrating it to the traditional 44-48% target strength. Cape Verde's earliest documented traces of cane-spirit distillation date to 1504, and the practice remains fundamentally artisanal, sustained by hundreds of micro-distillers producing small batches across the islands' villages, now the subject of a dedicated international academic research initiative (GRoG: Global Research on Grogue).
