Ingredients: Pineapple Vinegar Produced through traditional natural fermentation. As long as air is exposed after the lid is opened, sediment-color change and a transparent layer called "mother" may form on the surface of the vinegar. These are not signs of spoilage and the vinegar can be filtered again and used. This indicates that fermentation is continuing - the vinegar has not been pasteurized and filtered. It does not contain any chemical additives, preservatives or dyes. Store in a cool place with the lid closed and protect from sunlight. There is no. Naturally fermented vinegar is an indefinite product. The batch number is the production date.
