I have a bottle of sesame oil I think I bought about 8 years ago. I never opened it and it has been in the back of my bottom cabinet (fairly dark and cool) pretty much ever since then. I want to use it in a recipe, but not if it is spoiled. There is no date on the bottle anywhere so I am dating it by the price tag - and it is of a store I haven't shopped in since we moved 8 years ago.
So, how will I know if it is bad? Since it has never been opened, do you think it is ok to use?
Does sesame oil go bad?

Honestly, I wouldn't trust it after that long. Have you smelled it? Your first sniff of it should let you know if it is rancid. :tongue_smilie:Most oils will last a year or two unopened, but after opening just 4-6 months. But any oil will get rancid over time, regardless of how it was stored. I would toss it, and then buy a new, small bottle. If you have some sesame seeds, you can toss them briefly in regular oil and flavor that oil with it's lovely good sesame taste.

Rancid oil is really easy to detect--usually by smell, but a tiny tast will tell as well.. I have no idea how long oil keeps unopened.

Nut oils go rancid easily. I wouldn't trust it at this point. I keep my sesame oil in the refrigerator.
