I came across a paper today on the isolation of a newly identified S. cerevisiae strain from an indiginous Ethiopian mead called ogol. While the info on the new strain was interesting, it is also moot for most of us in the world (the strain is currently undergoing research in Tokyo for possible applications in the brewing industry there, and will not likely be available in the U.S. for many years, if ever -- so unless you have connections in the Japanese brewing industry, or are planning a trip sometime soon to the Gambella Region of Ethiopia, you aren't likely to get a sample to play with).
What really interested me was the the described process of making ogol, various pieces of which I quote below, that clearly indicates that it is a true mead -- which we define as an alcoholic beverage made with fermented honey as its primary sugar -- as opposed to t'ej, which, as Miriam has shown, is more like a lambic-style beer backsweetened with honey, and not a true mead at all. The ethnic group that makes ogol, the Majangir, seem to be a relatively small part of the population, and therefore it seems unlikely to me that this exact mead is the honeywine of Ethiopia. More likely, it is a local version of a regional drink which spans ethnicities, cultures, and languages in this, and maybe other nearby African countries.
While ogol is likely not the definitive "Ethiopian Mead", it may well be one of several such being brewed locally throughout the region. How t'ej has come to be so completely (and apparently incorrectly) identified in this fashion also needs further investigation, I think. There's a massive amount of misinformation about t'ej in the (Western) mead community, and I can only hope that it will be dispelled at some point in the near future.

Characteristics of fermentation yeast isolated from traditional Ethiopian honey wine, ogol
Accepted 20 December, 2005
Indigenous honey wine, known locally as ogol, was collected in a village of the Majangir ethnic group in Southwest Ethiopia, and the procedure for ogol fermentation was investigated.
The precise method for making ogol was determined during fieldwork in Southwest Ethiopia.
Procedure for ogol brewing
Four hundred ml of pulverized bark of the native tree, mange (Blighia unijungata Bak), 500 g of wild honey, and 1.5 l of fresh well water were mixed and incubated at room temperature in the tropical area for about 2 weeks or more to propagate the yeast and prepare a seed culture called bite (Figures 1 and 2). Mange was one of the plants of the honey source as well. The bark might provide some nutrition for yeast growth and chemical compounds that prevent microbial contamination and function as a kind of supporting material for the fermentation yeast.
Around 3 to 4 kg of wild honey containing beeswax and bodies of honeybees was diluted with well water to 10 to 12 l. Diluted wild honey was inoculated with bite as described above in a 15 l earthen pot. The pot was placed next to a dying fire to maintain the mixture at the proper fermentation temperature. Wax and other residues floating on the surface kept the fermentation more anaerobic, and the impurities in the wild honey served as yeast nutrients (Steinkraus, 1983).
After 1 night to 3 days, the fermented mash was ready to be drunk (Figure 3). It was strained to prepare the ogol. The residue composed of the bark and viable yeast cells was recycled to prepare bite for the next batch of ogol brewing. When recycled bark containing yeast cells was used, it took only 2 to 3 days to prepare the bite for the next batch.
While ogol is likely not the definitive "Ethiopian Mead", it may well be one of several such being brewed locally throughout the region. How t'ej has come to be so completely (and apparently incorrectly) identified in this fashion also needs further investigation, I think. There's a massive amount of misinformation about t'ej in the (Western) mead community, and I can only hope that it will be dispelled at some point in the near future.
