Oil storage - importance of air-tight seal

[seans_potato_business]

I purchased one of these bottles for oil, just because I thought it looked nice. I'm now wondering whether oil stored in this bottle will go rancid more quickly since the closure it not air-tight?

I have two of these bottles. One for vinegar and one for oil. I no longer keep the vinegar in one because I found that it was evaporating. But I do with the oil. I use the oil often enough that having it go rancid is not a problem. One of the benefits of having my oil in it, is that because the opening is so small, I find I use less. Or just the right amount. Whereas the bottle it came in has a wider opening and too much pours out. (The more you use, the more you buy.) It is a great tool for helping you to use less fat in your diet.

I use similar bottles for the oils I use most often. However, my everyday olive oil bottle is ceramic and the glass ones are dark green. Preventing light from reaching the oil will help it to last longer.

I'd be as concerned about exposure to light, but in our small household (2 people) 500 ml is not around long enough to go rancid.
