How long does unfiltered vinegar last? I bought some in Sept. and can see the settling in the bottom. Should I be worried? Or just careful when I pour? Or am I supposed to shake it up before using?

The sediment is natural, just shake it gently and keep it in the fridge.
If it gets bad or you become worried you can filter it through a fine mesh strainer, or damp coffee filter to clean it up.
