If the funding is successful, you will receive a personalized Christmas card by 15 December 2014, accompanied by a message that the Christmas gift will consist of KEFIRKO with swizzle stick and a printed booklet with user manual and 30+ recipes.
The top lid is screw-on and has a specially designed inner rim. If you unscrew the lid just a tiny bit, the fruit flies will not be able to get inside the jar while your kefir will still get enough airflow for fermentation.
The sieve was tested with water grains too: the slots are V-shaped and designed to keep the grains of all sizes in. Due to gravity the smaller grains remain on top of the bigger ones when you pour the water kefir out of the jar.
