You may think that it is a good idea to refrigerate your olive oil, based on what I have been telling you so far i.e. the darker, the cooler, the better However, I don’t advise storing EVOO in the fridge The cooler temperature will cause the olive oil to cloud & solidify. Yes, it will return to liquid once it is back at room temperature, but the repeated temperature fluctuations can reduce its quality & freshness.
