Kefir Fermenter for Water Kefir 1.0L Water Kefir Fermenter has spigot at relatively high level, while grains stay on a bottom. You don't need to remove grains when transfer liquid to plastic bottles: just open spigot and drain mixture. Upper lid has tiny holes for aeration and protection even from small flies. Lower lid doesn't have holes. It is "storage lid". You don't need strainer and funnel to fill bottles: spigot makes thin but strong stream. See Instruction at Images
