beets

i am well on my way to beet kvass.  it has been 24 hours since i cut up the beets and covered them with water and the required salt and some whey.  there is a bit of frothy film on the top of the liquid so i know that chemistry that is supposed to be taking place is actually taking place.  in a couple more days i will put this into the fridge and when it is chilled i will reluctantly sample of the result.  it is always a question of that first sampling...is it safe to drink?  will i suffer ill effects? will i like salty beet water?  until then i feel safe as an observer in this experiment:)
