We recently added fermenting crock pots to the website here: http://www.wheatgrasskits.com/nik-schmitt-fermenting-crock-pot. These are great for making sauerkraut and preserving vegetables using lactic acid fermentation. Ann Wigmore recommended lactic acid fermented vegetables as part of her raw foods diet. Lactic acid fermentation preserves vegetable nutrients and adds beneficial bacteria essential for proper digestive health.
Virtually all store bought pickled vegetables and sauerkraut has been pasteurized which kills off the vital beneficial bacteria. It is possible that you have never even tasted real sauerkraut or pickled vegetables preserved in this ancient method.

Also Dr. Mercola has a great article on the benefits of lactic acid fermentation: http://articles.mercola.com/sites/articles/archive/2012/12/15/caroline-barringer-interview.aspx
Look for more lactic acid fermentation products to be added in coming months.
