Is there a best way to store your EVOO?

Extra virgin olive oil (EVOO) is a pure fruit juice and as such will naturally oxidize and lose its aromas over a period of around two years, even if stored in the best conditions. To slow down this process it is therefore important to prevent any excessive exposure to heat, oxygen and UV rays.

Singapore’s climate conditions are very different from the climate conditions of the Mediterranean, and given the high temperature and humidity, some of us may be tempted to put extra virgin olive oil in the fridge. However, EVOO has the peculiarity of becoming solid at around 13 degrees Celsius, and an EVOO which has solidified in the past will be less stable when exposed to oxygen.

The ideal storage temperature for EVOO is 18 degrees Celsius, but since the EVOO we select have high polyphenol levels (which make it more resistant) compared to mass market EVOO, we have observed it can be fine when stored up until 27 degrees Celsius. The worst storage spot for EVOO in your kitchen is definitely next to the stove, where it will quickly be exposed to temperatures above 30°C, as well as light.

Good old cupboard

The best storage spot for EVOO is therefore simply a convenient cupboard or drawer, where the oil will be protected from both heat and UV rays. Beware of cupboards located near sources of heat as well. If your place is equipped with a temperature-controlled wine cellar, you may also use this for EVOO storage, though ideal wine storage temperature at 16°C is slightly below that recommended for EVOO, and modern wine cellars may let some level of UV rays in. A good practice is to always close the tap and replace the bottle in the cupboard or drawer after use.

And as always, please remember to finish your EVOO within 2 months of opening! The opening of the tap marks the start of the countdown… once air starts entering the bottle and replace the oil as you use it up, it will slowly oxidise the oil. EVOO does keep much longer than wine, as the polyphenols present in the oil will slow down the oxidation process, but they will not prevent it.
