This is the best I have ever found. We now buy it by the case. When we receive our oil, we put the oil in quart canning jars and put a vacuum pump on the lid and suck the air out of the oil first thing. Air in the oil, light and heat destroy oil faster than anything. We remove the air from the oil, store it in glass, in a cool room, underground/basement. It lasts for a year or more this way. If you do anything like this at all, be sure to date the oil, when it was squeezed as well as when it was put in a jar.
