    Shelf life of Grapeseed and Olive Oil

    Cleaning out the pantry to prepare for the remodel and ran onto a bottle of expensive grapeseed oil and Olive oil with spices in it for dipping. Both unopened and kept in a cool dark environment for 10 years! Toss them or use them?

    If in doubt throw them out. That would be the safe thing to do, although I suspect the are still good.


      Is there not a best before date on the bottles?
      My first impulse would be toss em


        With oil, I would give it a sniff and taste test. If it is rancid, it should be obvious.

        EDIT: I will go with the world renowned Troutman on this, and say throw it out. Unless you are participating in the "use expired rancid oil challenge" of course! Some foods, like honey, never really go bad if stored in a sealed container, even though they may crystalize.

        About the only oil I have in my pantry that MIGHT go a full year before I use it up are some flavoring oils like Toasted Sesame oil. However, I also buy that in small containers, and not in gallon jugs.

          According to the old Interweb, properly stored oils should last around 18 months or whenever the expiration date stamped on the container says. If you have 10 year old oil I'd toss it.


            I would put it in my lawn mower with some basil and garlic to make mowing more enjoyable!

            Well it looks like they go to the bin. I can't believe they hid in the corner for so long.

              Last time I cleaned out our pantry I found a tetra of pea soup....best before some month in 1999....tossaroo....

            I would save it for a squeaky door hinge, but not for food.


              I get this question a lot in the soap making groups I belong to.

              Your nose is a good detector of rancidity. If the fat has little odor, but what odor there is is mild and sweet, it's fine. If the fat smells like old crayons, or has an obvious "fatty" or stale odor, or just plain stinks ... use it for a non-food purpose or discard it. Most people don't even use rancid fat for making soap, because the rancid odor persists in the finished soap.

              Both fats are high in unsaturated fatty acids, so it's likely they're going to be rancid. Even though they've been stored under ideal conditions, ten years is a loooong time.


                I like to use old oil in my firepit

              The amazing Karubecue is the most innovative smoker in the world. The quality of meat from this machine is astonishing. At its crux is a patented firebox that burns logs above the cooking chamber and sucks heat and extremely clean blue smoke into the thermostat controlled oven. It is our favorite smoker, period.

              The Pit Barrel Cooker May Be Too Easy

              The PBC has a rabid cult following for good reason. It is absolutely positively without a doubt the best bargain on a smoker in the world. Period. This baby will cook circles around the cheap offset sideways barrel smokers because temperature control is so much easier.

              Masterbuilt MPS 340/G ThermoTemp XL Propane Smoker

              This is the first propane smoker with a thermostat, making this baby foolproof. Set ThermoTemp’s dial from 175° to 350°F and the thermostat inside will adjust the burner just like an indoor kitchen oven. All you need to do is add wood to the tray above the burner to start smokin’.

              Is This Superb Charcoal Grill A Kamado Killer?

              The PK-360, with 360 square inches of cooking space, this rust free, cast aluminum charcoal grill is durable and easy to use. Four-way venting means it’s easy to set up for two zone cooking with more control than single vent Kamado grills. It is beautifully designed, completely portable, and much easier to set up for 2-zone cooking than any round kamado.
