Kartheins Organic Sauerkraut is obtained through the natural process of fermentation that creates beneficial probiotic bacteria. Natural Probiotics are also added during the fermenting process for added health effects and to avoid re-fermentation. Unpasteurized Organic Sauerkraut is a new experience for most people, but it's recorded use goes back 6000 years. Unpasteurized or raw cultured means the sauerkraut is never subjected to heat. High temperatures destroy naturally occurring digestive enzymes and beneficial bacteria such as various strains of lactobacillus.

Karthein's Organic Unpasteurized Sauerkraut is prepared the old fashioned way in labour intensive small batches. - no vinegar - no preservatives - no destructive heat processing - made with certified organic cabbage and unrefined grey sea salt - manufacturing process is certified organic by Ecocert Canada.
