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 for 13 to 14 hours by lactic bacteria, boiled for hours and then fermented for about half a day with a traditional leaven called kpètè-kpètè. It is ready to drink after that fermentation, at about pH 3.2 and 4 % alcohol.

At a glance
Tchoukoutou is an opaque, sour beer brewed at home from red or brown sorghum malt. The malt is mashed, soured for 13 to 14 hours by lactic bacteria, boiled for hours and then fermented for about half a day with a traditional leaven called kpètè-kpètè. It is ready to drink after that fermentation, at about pH 3.2 and 4 % alcohol. Made in 7 steps over 5.1 days – 6.4 days. The longest step, germinate, takes 3–3.5 days (Lyumugabe F 2012). Saccharomyces cerevisiae, almost the only yeast dominating the fermentation does most of the fermenting.
Tchoukoutou boils its mash residue and then its wort for hours, souring the mash for 13 to 14 hours in between, and is fermented for only about half a day with a traditional leaven. Dolo and amgba also boil their wort; East African sorghum beers such as ikigage do not.
Leaven
Kpètè-kpètè, the traditional leaven added to the cooled wort (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, fluid beer, also made mainly from sorghum 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.
Kayodé et al. (2007) describe tchoukoutou as an ancestral beverage widely used in traditional ceremonies, and report that brewing income is used for household needs and partly for children's education.
