Wash the beets and peel if not organic or leave skin on if organic
Chop the beets in to small cubes, but don't grate.
Place the beets in the bottom of a half gallon glass jar.
Add the whey/sauerkraut juice and salt. If you don't want to use whey or sauerkraut juice, you can double the salt instead, though it may take longer to ferment.
Fill the jar the rest of the way with filtered water.
Cover with a towel or cheesecloth and leave on the counter at room temperature for 2 days to ferment.
Transfer to refrigerator and consume as desired. I drink 3-4 ounces each morning and night.
