A stupid comment, but not for the reason you might imagine. Brits don't buy Bertolli 😊 An Italian sounding name 😊 but they have suppliers in Italy, Spain, Greece, Tunisia, Portugal, Argentina, Chile, Peru...
A lot of the cheaper Extra Virgin in the U.K. comes from Spain. Used for general purpose and low temperature cooking. Not difficult to find single estate/region oils in the U.K. and it's not unknown for some to pop over to Sardinia to stock up on some fresh Bosana and Noccelara Extra Virgin direct from the farm.
As an aside, Big C Extra were knocking these out for 78 baht the other day: https://www.bigc.co.th/en/product/costa-d-oro-vitapiu-5-oils-1-l.3876860
Picked some up to use in fresh seasonings and vegetables stored in oil, such as sliced mushrooms etc.
