It was evaluated different traditional kefir grain populations and their derivatives, kefir, kefir leban and kefir whey, regarding physicochemical and sensorial characteristics when inoculated into different standardized milk concentrations, with incubation time/temperature, maturation and filtration variables. The manipulation of the population of kefir grains was effective in obtaining products with similar physicochemical characteristics and the volume of milk used in the incubation significantly influenced the characteristics of derivatives. The sensory evaluation of kefir leban food formulations such as spiced hors d'oeuvre, showed good acceptability.
