Many foods are stored in vinegar. But did you know that vinegar itself should be stored properly? Here is how.
Use the right container. Vinegar is acidic. As such, it should not be stored in containers made from brass, copper, iron or tin or corrosion and leaching will set in, creating reactions between the metals and the vinegar and therefore damaging the food. The safest container for storing vinegar in is glass.
Store the vinegar in a cool, dark place. You can even put it into the refrigerator. Although vinegar is the product of wine having gone bad, vinegar can also go bad after a while and it tends to lose flavor after it is opened. Store for around 6 months; after a year you will probably find that the vinegar doesn't taste as good as it did when first purchased. Fruit and herb vinegars are best kept in the refrigerator as this keeps their flavor at its best.
Keep the lid closed tightly. In between use, avoid contact with air by ensuring that the lid is on properly. Don't leave the lid off for storage.
