How Long Should Naked Kraut Ferment?

IMG_8070.jpg

Greetings!!
I followed the book “fermented vegetables” and it seemed my ferment was ready at five days. 
I didn’t want it too sour/“nasty” (my husband and a dear friend were skeptical at letting it sit too long) so i tasted it and jarred it up. it’s in the fridge. My first kraut. Naked kraut. 
Do you think I rushed it? 
We keep our house at 65F year round and i had this in a crock in my sewing room above our boiler room. 
Thank you!!!!

Hi there, 
Congratulations on your first Naked Kraut. Sorry for the slowish response. We have been traveling a lot. These look great. I am guessing you are enjoying them by now. As soon as the kraut smells pickley then it is technically done. As the time increases it just gets more sour. The only reason to let it go more is that it will continue to process the carbohydrates and “predigest” them for you. That said these younger ferments are super tasty and still good for you. 
Enjoy,
Kirsten
