Ok, turning to Wikipedia:
"
Grape seed oil (also called
grapeseed oilor
grape oil) is a
vegetable oil derived from the
seeds of
grapes."
"
Rapeseed (Brassica napus subsp. napus) is a bright-yellow flowering member of the family
Brassicaceae (mustard or cabbage family), cultivated mainly for its oil-rich seed, which naturally contains appreciable amounts of toxic
erucic acid.
Canola are a group of rapeseed
cultivars which were bred to have very low levels of
erucic acidand are especially prized for use for human and animal food. Rapeseed is the third-largest source of
vegetable oil and second-largest source of protein meal in the world."
"
Canola oil is a
vegetable oil derived from a variety of
rapeseed that is low in
erucic acid"
Ok, rapeseed and canola, at least derived from the same plant, grapeseed is different all together. I do remember reading years ago, I think, that "canola" is a made-up name, more for marketing, to avoid the term "rapeseed," for the North American market.
I remember driving through England and seeing absolutely stunning fields of bright yellow...and then my sinuses immediately seizing up.
