Do I need to store a mixture of olive oil and balsamic vinegar in the refrigerator?

1As you probably already know, pay attention to the fact that Extra-virgin Olive Oil is very different from simple Olive Oil. The latter being the "poor quality brother"...– drAlberTNov 4, 2010 at 15:11

As a general principle, any ingredients which do not require refrigeration on their own will not require refrigeration when mixed. A notable exception is raw garlic in olive oil; raw garlic carries botulinum spores, which propagate in anaerobic environments. Cold helps to prevent the spores from multiplying and producing toxin, but doesn't prevent it entirely. In addition, you will find texture effects; olive oil is fairly unique among unprocessed (as in, unhydrogenated) vegetable fats in that it solidifies at refrigeration temperatures.

I have a bottle of peanut oil that has turned into "slush" in the fridge. It is not a problem because it re-liquefies in a minute or two. Dec 21, 2010 at 0:03

Another exception is water. Many dry things when mixed with water will spoil.– MichaelNov 17, 2019 at 20:38
I don't think so unless it's not pure mixture of oil and vinegar as I think both of them can be stored un-frigerated independently.

Olive oil also tends to get flakes when cooled, however these will simply 'melt' when it warms back up Nov 3, 2010 at 16:54

This is precisely what had happend to my oil making it look ugly. I had a feeling it didn't have to be refrigerated. Nov 4, 2010 at 14:53
Extra-virgin Olive Oil is a product with long life (one year until the next season will produce the next generation of products) and is stored at environment temperature, as long as it is prevented to be exposed to light and heat.
Modena Traditional Balsamic Vinegar is a very long life product, deriving from a long term process during years, environment temperature too.
Mixing them will not change they cold-affinity, so prevent the mixture from direct light and eat, no need for a refrigerator at all.
