Storing Olive Oil

Olive oil is not like a good wine; it does not improve with age.
According to our registered dietitian, once opened, you should use the
oil within three months for optimum flavor. Store it away from light
and heat, in a tightly sealed container. 
 
It is OK to store olive oil in the refrigerator.Some believe that this might affect its flavor a little bit, but it also improves the shelf life of your oil.
 
Substituting olive oil for other fats can be a heart-healthy cooking
strategy!
