I have nothing to do with the company below, but I AM half Greek, and my Greek mother is 90 years old and going strong. Even in the war, when she was in Athens, and starving, her mother used to walk for hours across the city in search of olive oil. Bread: they had none.
Michael mentions in his book the problem with counterfeit extra-virgin olive oil and on this Clever Guts site he says that although he has not yet managed any definitive listing of safer brands, he recommends small, individual companies. I read in his book about unripe olives etc – so here we are …… and of course, he’s right about price, too.

Or just see below ( I’ve pasted from site)
This is the first olive oil of the season, made from unripe olives when they are still small and green. A truly superior olive oil with intense flavour and a unique grassy taste.
