Banana beer is made from ripe (but not over-ripe)
East African Highland bananas (
Musa acuminata Colla (AAA-EA),
Mbidde clone set). To accelerate the ripening of bananas, a hole is dug in the ground, lined with dried banana leaves which are then set on fire. Fresh banana leaves are laid on top of them, then the unripe bananas. These are then covered by more fresh
banana leaves and pseudostems. After four to six days, the bananas are ripe enough. Two types of banana are used for banana beer: the harsh tasting
igikashi and the milder tasting
igisahira. The banana beer mixture consists of one third
igikashi and two thirds
igisahira. Once ripened, the bananas are peeled. They are not ripe enough if they cannot be peeled by hand. After peeling, the bananas are kneaded until soft. The juice is then filtered to get clear banana juice, which is then diluted with water.
Sorghum is ground, lightly roasted, and then added to the juice. This mixture is left to ferment for 24 hours and then filtered. After filtering, the beer is packaged in glass or plastic bottles. In commercial production, the beer may first be
pasteurized before packaging to stop fermentation and extend shelf life. ==Varieties==
