Flaxseed Oil question

[Cut]

I bought my first bottle of Flaxseed oil recently and have a few questions.
I read in an article that if the oil tastes even slightly bitter it should be thrown out because it can quickly become rancid. The thing is the bottle I bought was the last on the shelf, and when I got home I noticed it was leaking. The seal didn't seem broken though but when I tasted it, I did notice a slighty bitter taste. Is this normal or should there be no bitterness at all?
Also, do you guys keep the flax oil in the fridge because I read that this was important too.

Thanks.

Get your bottle back to where you bought it

don't consume this oil
it is rancid

and keep any flax seed oil (liquid) int he fridge
