Walnut oil keep?

How long does walnut oil keep?  Do you keep it in a fridge?

    About a year if protected from light, heat and oxygen. But that is for food use, a slight taste of rancidity will not deteriorate its art benefits. A fridge will assist in slowing the oxidation. Keeping air out of a well sealed bottle is important.

    The addition of clove oil (2%) is an antioxidant preservative for the walnut oil.

    A new bottle is only a few dollars in the supermarket and I have no problem buying a new supply every year.

  •  @dencal do you buy artists grade or just what’s at a grocery store?
