Banana wine is a fruit wine made exclusively from bananas. It is different from banana beer, which has a long tradition and great cultural significance in East Africa. Blocker et al. (2001) wrote a chapter on "Banana Wine" in the book "Alcohol and temperance in modern history: an international encyclopedia", though this is slightly confusing, as they define what is traditionally referred to as banana beer as being banana wine. The data they present on Production Techniques and Social Practices and Rituals relates to the latter and not to what is commonly known as banana wine.
In Tanzania, banana wine is made commercially by fermenting peeled, mashed, ripe bananas. Water (to dilute the rather thick banana mash), wine yeast and sugar is added to the "banana mash".
The traditional banana beer processing (as described in the banana beer page and in Blocker et al. (2001)) is different from commercial banana wine processing. For example, the process of making banana wine used by Banana Investment Ltd. is as follows:
In commercial production, ‘Cavendish’ bananas are used, while in informal production, a variety of cultivars, including both cooking and beer East African Highland bananas,‘Pisang awak’, ‘Gros Michel’ and Apple bananas are used. Commercially produced banana wine is a clear, slightly sparkling alcoholic beverage with a longer shelf-life than banana beer, which is spoiled easily and therefore not stored for long periods. Depending on the strain of yeast and amount of sugar added, the sweetness and alcohol level in the final product is variable.
Production of banana wine is mostly at a small-scale level, though attempts have been made to bring it up to industrialized production, and there are commercial producers of banana wine (i.e. Arusha-based Banana Investment Ltd).
Since the early 2000s, attempts have been made to expand banana wine production to other countries where the crop is prevalent. The Philippines government has sought to expand a local banana wine industry, while India has produced both award-winning banana wines and research into expanding production.
The French Caribbean island of Guadeloupe now produces banana wine.
