I wonder too. Simply in the plastic bottle it came in, unopened, no sunlight. Was 3 years old.
It was stored in a non climate controlled place. So temperatures will have ranged quite a bit over the years (-10C to 30C are the min/max where I live). Perhaps that was a problem?
I’ve had sunflower oil go rancid before. Is it perhaps due to bad storage?
How? Opened and on sun during a few months?
