Technique

Malting the sorghum
Sprouting develops enzymes that convert starch to fermentable sugars
Wild/spontaneous fermentation
Yeasts and lactic bacteria produce both alcohol and the signature sourness
Back-slopping (using prior brew as starter)
Carries over an active microbial culture for a reliable, fast ferment
