Olive oil being poured into bowl with bowl of olives in the background

Answer:

It is not necessary to refrigerate an unopened bottle of olive oil. Even after being opened, refrigeration is not necessary as long as stored properly. However, if you won't be using an opened bottle for several weeks, refrigeration may help preserve the oil until you need it. Just be sure to let it warm to room temperature afterward so that it is completely liquid before using.

I have never refrigerated my olive oil. I buy the large bottles and I keep them in them in a cool dark place. A large bottle last me about a month and in that time i have never had a bottle go rancid. I have however had a bottle of vegetable oil go rancid i had kept and hadn't used all of it before its expiration date. It was awful!

Oils left outside go rancid. But the various beneficial substances are better maintained in the dark. So the bottles should be dark or kept out of sight.

When the large bottle of refrigerated olive oil has come to room temperature I pour about 1/4 cup or so into an empty bottle that I keep in the cupboard. That way there is always some ready to use.
