vergister
A vergister is a vessel or chamber used to carry out fermentation (vergisting) processes. In industrial and agricultural contexts, a vergister provides the environmental conditions—such as temperature, mixing, pH control, and, where appropriate, oxygen or anaerobic conditions—needed for microorganisms to convert substrates into desired products. Common applications include beverage production (beer, wine, spirits), dairy fermentation (yogurt, kefir), and bioenergy or waste processing (anaerobic digestion for biogas). The term encompasses devices from laboratory flasks to large industrial tanks.
Design and construction: Vergisters are typically made from stainless steel or glass-lined steel, though concrete or
Operation: Fermentation begins with inoculation of microbial cultures. Operators monitor and adjust parameters such as temperature,
