Borgla has developed the Kefirko system for homemade kefir preparation and other utensils for the preparation of fermented foods at home, marketed under the brand name Kefirko. It consists of a special glass container and a two-layer lid, which regulates the flow of air and maturation of kefir. Using this system, the final beverage is separated from the grains without the use of other utensils and above all, without messing up the kitchen.
