Personal portable device for fermentation

A portable device for fermenting milk into kefir from at least one kefir grain agglomerate, the device comprising:

• a container having an upper opening, the container defining a reaction space therein for containing milk;
• a lid removably attachable to the upper opening of the container to enclose the reaction space, the lid including a plurality of holes for the passage of air into and out of the reaction space;
• a separate chamber defining an internal space configured for containing at least one kefir grain agglomerate, the chamber dimensioned for being wholly insertable into the reaction space of the container;
• the separate chamber including a plurality of ports formed therein for providing the flow of milk in the reaction space into and out of the chamber internal space to contact the at least one kefir grain agglomerate therein for fermentation to form kefir;
• and
• an elongated tube adapted to project through an opening in the lid and into the reaction space of the container, the tube configured for allowing the drinking of kefir fermented from milk from the reaction space of the container;
• the elongated tube engaging the separate chamber and passing therethrough isolated from the internal space for supporting and suspending the chamber in the reaction space of the container for fermentation while allowing drinking of kefir from outside of the chamber internal space.
