Storage

Why is clear plastic or glass packaging bad?

Extra Virgin Olive Oil is very sensitive to light, air and heat. Given the proper storage conditions you olive oil should last you over a year without any issues. Olive oil is best stored in a dark place that stays at room temperature, like a cupboard. NEVER store olive oil in the refrigerator as it will coagulate and lose its flavor. It will stabilize again at room temperature and is still good but it is not advised. salad dressings and such are fine in the refrigerator but may need to me mixed once removed from the cold. Parthena’s Food Grade Stainless Steel packaging is excellent because it keeps out the light, and air keeping your products fresher longer. Also, because we don’t use glass you can show off your great new oil on your table or counter top without worrying about it losing quality!

It is also advised to NEVER buy any olive oil in clear packaging for these same reasons, clear glass and even 75% of tinted glass does not protect the olive oil. Many cheaper suppliers have been known to use tinted glass to simulate the quality of Italian glass – which has a dark green appearance and built in UV protection. The Chinese glass may look green but does not have the UV resistance.

Tin cans used for the larger 3L sizes and larger are also used for packaging which do eliminate light, but recent studies have shown that the acidic properties of olive oil can react with the tin which ultimately degrades the quality of the oil.

How should olive oil be stored?

We suggest that you  keep your olive oil away from all sources of light and heat, so basically the worst place you can keep your olive oil is on your kitchen counter or next to your stove. Instead, store your olive oil in a dark cupboard. Once you have opened your olive oil it is good for a year! Parthena EVOO has unique Food Grade Stainless Steel packaging that is resistant to light and will allow you to keep it out on your countertop or on your table without degrading the quality.

Why is our oil in cans?

It is a question of quality – Food Grade Stainless Steel protects the contents from the deteriorating effect of light. Even a few weeks of light exposure will accelerate the aging of olive oil. The fact that so many olive oils are in clear bottles is certainly a question of marketing. Tin cans which are quite common are also advised against because olive oil and tin can react spoiling the oil. 

 

Should olive oil be kept in the refrigerator?

No, EVOO will become cloudy and thick under refrigeration. And, as with wine, we have found that extended refrigeration can result in diminished aromas and muted flavors, even after the oil is back to room temperature.
