Nut oil longevity?

  • f

How long would you say hazelnut and walnut oil last in cans that have been refrigerated since opening?

  1. Walnut oil turns rancid very quickly. Refrigeration will prolong its life a bit, but your nose knows. If it smells off or tastes bitter, then it's time to replace it. I recommend buying in small bottles...

    not sure about the other but the same principle applies.

      I have some hazelnut oil from last year that I have kept in the fridge...tasted it recently and it seems good. Most of the recipes that I use it for are Autumn types of dishes, and I just did not use it at all over the summer, so I am glad I can still use it and don't have to get another bottle.
      The sure way to tell is just to taste it, a little bit by itself on a spoon.
      Walnut oil always seems to go rancid before I can use it all , so I have not even bought any for a long time, I don't even buy walnuts in bulk any more, just what I know I will use in a week....Fresh walnuts are showing up from this season in the Farmers markets here...

        Thanks, its good to know the hazelnut (aka filbert) oil is more stable over time if stored in a cool place.

    2. I have had a jar of Macadamia nut oil in the fridge for 3 years, and it still smells/tastes great. (I keep my fridge pretty darn cold).
