Kefir grain is not necessarily needed for making Kefir.
You can buy a bottle of Kefir at Merivale Costco. Take one table spoon Kefir and add two cups of milk, rest it in room temperature and it will be ready after 24 hours.
I have made Kefir this way for over a year. I think it is easier than using the grain. The key to the success was to use a clean container that was absolutely oil free.
