When you purchase fresh Extra Virgin Olive Oil (EVOO), it is important to store it properly to ensure it retains its wonderful flavor and many health benefits. The three biggest threats to EVOO are heat, light, and air! Exposure to these three things will cause oxidation, and thus rancidity, in your olive oil.
The best place to store your olive oil is in a dark, cool location such as a wine cellar or cupboard. Never ever keep your olive oil near the stove, while it might seem convenient, it will expose the bottle to too much heat and cause it to spoil more quickly. With proper storage your EVOO will last for up to 18 months, however it is always best to consume your olive oil within 12 months of pressing. Unlike wine, olive oil does not get better with age.
Since light and air are two of EVOO’s enemies, it should come as no surprise that a good storage container is necessary to extending the life and continued health benefits of olive oil. Olive oil enthusiasts should store their EVOO in either tinted glass or nonreactive metal containers. Stainless steel is a good choice, but he sure to avoid metal containers made of either copper or iron.
Olive oils are delicious and offer a multitude of health benefits, but they are fragile, so make sure you are treating them properly.
