True Nature Apple Cider Vinegar is 100% naturally fermented to 5% acidity from the finest and delicious Himalayan grown apples. It is unfiltered and unpasteurized and hence retains the benefits of the natural residue & Mother and also retains essential minerals like sodium and potassium required by the body. Following are the unique things of my product: 1. It is manufactured in Shimla where the qualities of the Apples are the best in India. 2. To manufacture the Apple Cider Vinegar we require less temperature since it is a two-step (Apple Juice to Cider and then Cider to Vinegar) bacterial fermentation process. Shimla being a hill station with the desired temperatures gives us that leverage so that we manufacture it naturally instead of creating low temperatures artificially in the manufacturing setup if it is located elsewhere. Product Description: 500ml plastic packing (Plastic Used is food grade plastic) 18 months shelf life from the date of manufacture. No refrigeration required.
