How to Make Banana Beer

Product description

Banana beer is made from bananas, mixed with a cereal flour (often sorghum flour) and fermented to an orange, alcoholic beverage. It is sweet and slightly hazy with a shelf-life of several days under correct storage conditions. There are many variations in how the beer is made. For instance Urwaga banana beer in Kenya is made from bananas and sorghum or millet and Lubisi is made from bananas and sorghum.

Preparation of raw materials

Ripe bananas (Musa spp.) are selected. The bananas should be peeled. If the peels cannot be removed by hand then the bananas are not sufficiently ripe.


The first step of the process is the extraction of banana juice. Extraction of a high yield of banana juice without excessive browning or contamination by spoilage micro-organisms and proper filtration to produce a clear product is of great importance. Grass is used as an aid in obtaining clarified juice.

One volume of water is added to every three volumes of banana juice. This makes the total soluble solids low enough for the yeast to act. Cereals are ground and roasted and added to improve the colour and flavour of the final product. The mixture is placed in a container, which is covered in polythene to ferment for 18 to 24 hours. The raw materials are not sterilized by boiling and therefore provide an excellent substrate for microbial growth. It is essential that proper hygienic procedures are followed and that all equipment is thoroughly sterilized to prevent contaminating bacteria from competing with the yeast and producing acid instead of alcohol. This can be done by cleaning with boiling water or with chlorine solution. Care is necessary to wash the equipment free of residual chlorine as this would interfere with the actions of the yeast. Strict personal hygiene is also essential (Fellows, 1997).

For many traditional fermented products, the micro-organisms responsible for the fermentation are unknown to scientists. However there has been research to identify the micro-organisms involved in banana beer production. The main micro-organism involved, is Saccharomyces cerevisiae which is the same organism involved in the production of grape wine. However many other micro-organisms associated with the fermentation have been identified. These varied according to the region of production (Davies, 1994).

After fermentation the product is filtered through cotton cloth.

Packaging and storage

Packaging is usually only required to keep the product for its relatively short shelf-life. Clean glass or plastic bottles are used. The product is kept in a cool place away from direct sunlight.

Measure the following physico-chemical properties and and adjust accordingly to your set standard. Properties should be uniform every batch.
a. sugar content. Sugar concentration can be increased by adding sugar or can be lowered by adding water or pulp.
b. pH. This can be lowered by adding citric acid or can be increased by adding water or pulp.
c. titrable acidity. Adjustment can be made by mixing different concentrations or addition of citric acid.
d. alcohol content. Adjustment can be made by mixing different concentrations.
Adjustments can be computed using Pearson’s Square formula.
e. See standards for wine here.


  • nice. i found out that the the shelf-life for banana beer only last for several days. i just want to ask if there are any approaches or studies made to lengthen the shelf life for banana beerso that it will be available for industrial or large scale purposes without the fear of early expiration of product. thank you.

    • The storage life could be lengthen by pasteurizing the finished product and packing it properly.

  • […] had this for the first time on tour and fell madly in love with it. It tastes a bit like banana soda or a […]
