Soft drinks from Ghana
Asaana is a sweet-sour Ghanaian drink made from malted maize. The malt is milled, soaked and boiled until the foam clears, then strained and left to ferment for about three days before caramelised sugar is stirred in. In the Volta Region the same drink is called aliha. Made in 5 steps over 3 days. The longest step, ferment the wort, takes 3 days (Madilo F.K 2025). Lactic acid bacteria, which rise as the acid climbs between 24 and 72 h and Limosilactobacillus fermentum and the yeast Pichia kudriavzevii, isolated from spontaneously fermented aliha and tested as starters do most of the fermenting.

Asaana is a malted maize drink that is boiled before it ferments, soured for about three days and then sweetened with caramel, which gives its brown colour. Thobwa and togwa are thick malted porridges; asaana is strained to a thin drink.
Vended asaana often carries high counts of bacteria and fungi, including E. coli, because of poor hygiene during preparation and storage. Producers are advised to backslop or use starter cultures, which sour the drink faster and cut Enterobacteriaceae, and to keep the drink cold.
Hazards the sources name: Enterobacteriaceae, high early in fermentation; the 'original' method was highly contaminated; Escherichia coli and total counts above 10^6 CFU/ml in vended asaana.
Every number is labelled with how it is known. How this atlas is made
Asaana is a street and cafeteria drink across Ghana. Studies of aliha, the Volta Region form, find it made mostly by small producers with several different methods.
