Fermented bread or grain drink, extremely low alcohol (0.5-1%), extraordinarily high in B vitamins especially B12, rich in lactic acid bacteria. In African boza tradition made from sorghum or millet. A true ancestral probiotic with minimal preparation requirements.
The African boza tradition predates Eastern European kvass. When enslaved Africans arrived in the Americas, this ancestral knowledge of grain fermentation was part of their survival toolkit.
Fermented grain beverages produce measurable B12 via bacterial synthesis during fermentation — particularly relevant for Black Americans with higher rates of B12 deficiency from metformin use (common in T2D management). Lactic acid bacteria inhibit pathogenic bacteria and support gut-immune axis.
Use stale whole grain bread or cooked sorghum. Add water, a small amount of raw honey, allow to ferment 24-48 hours with raisins or dried fruit as natural yeast source. Strain, refrigerate.
