When it comes to olive oil here in Quebec I've found that there are only a small number of importers. Generally these companies import in bulk and bottle here, often under a variety of names for each importer.
It might not mean much, or a great deal (I don't know) but I've taken to seeking out extra virgin olive oils that are pressed and bottled in Greece or Italy. It may mean I pay a few bucks more, but I don't care.
I'm not adverse to anyone telling me that I'm wrong. In fact, if posters know why I shouldn't take this stance, I'd be pleased to read it. What I also want to find out is which brands are considered the best for folks who don't have the budget to blow on a bottle. Olive oil can get quite pricey, and I'm not even going into the realm of the "boutique" brands that you can only find in select shops such as those in the Atwater market.
I've seen bottles at Adonis going for upwards of $20+, and I know there are some out there that can command a small fortune. Keep it reasonable folks. Are Greek and Italian bottled imports actually better than those bottled in bulk here in Canada, and if so which (or, au contraire, which bulk brands are good)?
I've become wary since I've heard tales of importers passing off lesser grades of olive oil as better ones to command a higher price.
