Kirkland Organic extra virgin olive oil is not pure olive oil...

I do the same thing, but I save old wine bottles for the task.

See these? This is what I do - get yourself a kitchen funnel, and a bottle with a speed pourer on top (you can find them at pretty much any department store). Transfer your oils to one of them - the one on the left is olive, the center is vegetable oil, and the right is...well, empty right now. Anyway, the speed…

Mastro olive oil is a regular Walmart rollback and is used regularly by chefs everywhere (including some of Italian origin). It's no wonder that I regularly find the Mastro section of the shelf completely cleaned out.
