How funny/coincidental. I just ended my perpetual bone broth. I think I had it going for a week or week and a half. I'd let it go for a day or two, strain off the broth and put it into mason jars, then add more vinegar and water and let it go again. I thought it would never end. The broth did seem to get sort of light/mild after a while though. I only ended it because a) ran out of jars and b) got some beef heart I want to put in the slow cooker.
