Should apple cider vinegar be stored in an opaque container?

Apple cider vinegar should be stored at room temperature in a clean glass or ceramic container with a tight-fitting lid. Since vinegar is acidic, its acidity will cause metal containers to corrode over time. Additionally, exposure to light can cause the vinegar to lose some of its flavor and potency, so it is best to store it in an opaque container or keep it in a dark cabinet.
