Various schematics have been published detailing the methods for producing
kefir on an industrial scale.8,96,101,102 Rossi and Gobbetti103 outlined the details of a
continuous process for producing kefir using a multistarter made up of bacteria and
yeast isolated from kefir grains. Kefir was produced over a 30-day period; it was
lower in viscosity and lacked some of the volatiles normally found in kefir.
