It's a process. I didn't like spooning the "moldy" fermenting bubbly stuff off the top. Seemed really gross to me but I guess it's fairly normal, depending upon the temperature. Grandma use to keep her crocks of fermenting cabbage down in the cool "fruit cellar" but the stink still made it upstairs to the rest of the house......
But, like Norm said, it really is good tasting.
