Tchoukoutou and chakpalo (Benin and Togo sorghum beer)tchoukoutou
Tchoukoutou is an opaque, sour beer brewed at home from red or brown sorghum malt. The malt is mashed, soured overnight by lactic bacteria, boiled for hours and then fermented for about half a day with a dried yeast leaven called kpètè-kpètè. It is drunk while still fermenting, at about pH 3.2 and 4 % alcohol. Made in 7 steps over 5 days – 6.3 days. The longest step, germinate, takes 3–3.5 days (Lyumugabe F 2012). Saccharomyces cerevisiae, almost the only yeast by the end of fermentation and Lactic acid bacteria that sour the mash, and those carried in kpètè-kpètè do most of the fermenting.

What makes this one different
Tchoukoutou boils its mash residue and then its wort for hours, souring the mash overnight in between, and is fermented for only about half a day with a dried leaven. Dolo and amgba also boil their wort; East African sorghum beers such as ikigage do not.
Leaven
Kpètè-kpètè, a dried leaven saved from earlier brews (the name used in the Bariba, Denti and Yoruba languages)
Finished beer
Sour, opaque and pink, about pH 3.2 and 4 % alcohol
ChakpaloA clear, sweet, more fluid beer from the same malt.
Pasteurised bottled tchoukoutou (trial)3 h of fermentation in the bottle, then 15 min in a 75–80 °C water bath, kept the beer stable for at least six months (Osseyi et al. 2011).
Safety
Like other traditional sorghum beers it is drunk while still fermenting and keeps only about one to three days. In a trial, bottles fermented for 3 h and then pasteurised in a 75–80 °C water bath for 15 min stayed stable for at least six months.
Tchoukoutou has important social uses in Benin; it is an ancestral drink used in traditional ceremonies, and brewing it gives household income that goes towards family needs and children's schooling.
