Eden Organic Apple Cider Vinegar is naturally fermented with 'mother' of vinegar, a friendly natural bacteria culture similar to 'starter' used to make country bread. Appearing as cloudiness in the final product, the presence of mother indicates the best quality raw vinegar. The apple juice goes through a primary fermentation to reach the desired alcohol content, and a secondary fermentation to change the alcohol into acetic acid. Then it is patiently aged. EdenVinegar is bottled in amber glass to protect its flavor, bouquet and nutritional integrity.
