Kefir is a lot easier to make than yoghurt as it's not very temperature sensitive - cold temps just make it slow down a bit and room temp is fine for it to ferment. It's also cheaper as once you have some Kefir grains you just keep feeding them with milk and they'll continue growing so you end up throwing away unwanted grains.
