I had three batches of kefir fermenting and getting too much ahead. The three jars were strained and the grain all mixed in one jar, milk added for food, and stored in the refrigerator until needed for a new batch. This will be my seed grains for all future batches. It appears about half a liter per day will meet my requirements. The grains will be a mixture of some from a local supplier and some from a commercial supplier.
