There are three enemies of good olive oil: Light, heat, and hungry friends!
We don’t mind sharing our good oil with the third enemy, but we’re careful to keep oil away from the first two. .
Our oils are stored in a cool, dry room away from sunlight, So we’d suggest that you do something similar: store in the coolest part of the kitchen.
The worst thing you can do is keep your container of oil on a window sill, on the back ledge of your stove, or even in a cabinet right over the stove. You might be surprised at how often we see oil stored in those ways. It does not take long for the oil to turn rancid when it is exposed repeatedly to light and heat.
