The biggest sorghum crop the world produced in the last 40 years was inwith However, the microbiologically active characteristic of the beer also increases the safety of the product by creating competition between organisms.

Commercial sorghum

African sorghum beer brewed using grain sorghum undergoes lactic acid fermentationas well as alcoholic fermentation.

After the mix has fermented for several days, it is strained - a somewhat labor-intensive task. Some hybrids commonly grown for feed have been developed to deter birds, and therefore contain a high concentration of tannins and phenolic compounds, which causes the need for additional processing to allow the grain to be digested by cattle.

Sorghum is used in the same way as barley to produce a " malt " that can form the basis of a mash that will brew a beer without gliadin or hordein together " gluten " and therefore can be suitable for coeliacs or others sensitive to certain glycoproteins. The seeds and stalks are fed to cattle and poultry.

It was unknown in the Mediterranean area into Roman times. The natural microflora of the sorghum grain maybe also be the source of lactic acid bacteria; a handful of raw grain sorghum or malted sorghum may be mixed in with the wort to start the lactic acid fermentation.

This solved the problem of white rate-payers having to foot the cost of segregation, and ensured the whole scheme paid for itself. In Arab cuisinethe unmilled grain is often cooked to make couscousporridgessoupsand cakes.

It is aimed at those with coeliac diseasealthough its low-carb content also makes it popular with health-minded drinkers.

Despite the antiquity of sorghum, it arrived late to the Near East. Redbridge was the first sorghum-based beer to be nationally distributed in the United States. The most productive farms of sorghum were in Jordanwhere the national average annual yield was The last wild relatives of commercial sorghum are currently confined to Africa south of the Sahara — although Zohary and Hopf add "perhaps" Yemen and Sudan — indicating its domestication took place there.

Little research has been done to improve sorghum cultivars [ citation needed ] because the vast majority of sorghum production is done by subsistence farmers. It is called mabele in Northern Sotho and "brown porridge" in English.

This beer is said to be very thirst-quenching, even if it is traditionally consumed at room temperature.


For this reason, special plastic or carton containers with vents are used to allow gas to escape.
