You may want to read this page (see below) - there is a lot of good
information on oils and they indicate that expeller-pressed should also have
an additional refinement classification in the description on the bottle.

Now with a hydraulically pressed oil labeled "cold pressed" or "pressed",
you can assume you have a crude or unrefined oil. But this is not true of
"expeller pressed" oil because the common fate of expeller pressed oil is to
be refined after extraction. So you need additional information with the
words "expeller pressed". Organic Merchants will use either the word "crude"
or "unrefined" to identify this additional classification of acceptable
oils. So Organic Merchants draws the line of acceptability at this point
and, to review, you may expect us to carry only four classifications of oil:
(1) virgin (2) cold pressed (3) pressed (4) expeller pressed-crude. And this
paper is your tool to remind yourself of what we mean by those words.
