An Ethiopian earthenware vessel used for stages of tella, a traditional cereal-based fermented drink. Sources describe clay insira jars alongside modern plastic alternatives and document washing and smoke preparation before brewing.
The vessel and its names
Tella is a traditional Ethiopian fermented beverage made from cereal ingredients, and its brewing jar is known as insira or insera. A review also records gan or gaanii for earthen fermentation vessels in some contexts. Names, vessel choices and methods are not uniform across Ethiopia, so these terms should not be read as a single standardized pot design. The studied vessel is a sizable clay jar with an accessible upper opening; a published study shows clay pots used for tella alongside plastic jars.
In the 2020 comparison conducted in Dessie and Kombolcha, researchers used 20-litre clay pots and 20-litre plastic jars. Those figures describe that experiment, not a universal capacity specification. The sources do not establish a standard profile, wall thickness, closure or manufacturing method.
Preparation before brewing
Descriptions of tella preparation report repeated washing of the vessel with water and fresh grawa leaves, followed by smoke treatment. In one account, the clean vessel is inverted above smoldering splinters of weyra wood for roughly ten minutes. The literature describes this as customary preparation; it does not make the practice a general sanitation guarantee.
The jar is used through stages of brewing rather than only for storage. A review describes an initial mixture of gesho and water fermenting in a clay pot, followed by transfer or addition of further ingredients in a larger vessel during later stages. Household practice varies, and sources note that equipment, ingredients and process differ with region, community and economic conditions. Sources do not define one required lid or seal for every practice.
Clay and modern alternatives
Plastic containers appear in contemporary tella production alongside traditional clay vessels. In the Dessie and Kombolcha study, researchers compared tella made in each material under local conditions. The findings describe that experiment only: they do not prove clay always produces a better beverage or that vessel material alone explains differences in every household or region. A later review likewise emphasizes variation in methods and the lack of a single national standard.
The evidence supports an earthenware brewing jar as a traditional form, but does not establish when it first came into use, a universal size or one exact shape. It also does not support burying the jar. This entry records documented material, names and preparation context while leaving uncertain dimensions and acquisition routes unspecified.
Equipment details
CapacityNo universal capacity is established. A 2020 comparison in Dessie and Kombolcha used 20 L clay pots and 20 L plastic jars; these are the study's vessels, not general specifications.
SizeThe sources do not establish a standardized profile, wall thickness or closure. Published study images show clay pots used for tella brewing.
How you get oneNot established A study reports local-market access, but sources do not establish a general or current purchasing route.
CarePublished descriptions report washing the clay vessel repeatedly with water and fresh grawa leaves, then inverting it over smoldering weyra wood splinters for about ten minutes before use. These describe cited practices, not a general sanitation guarantee.
Made of
- earthenware clay
The documented traditional brewing vessel is clay. Plastic jars or buckets are modern alternatives; sources do not establish one standard material or form across Ethiopia.
