I was driving to the local bottle supplier the other day and was surprised to see olive picking nets laid under the trees. Very early I thought and then remembered that one of the local producers produces an oil which made from olives picked on the 5th new moon after the olives have flowered. They call it "La Quinta Luna".
This is today - 27th September.
I have tasted the oil before and because practically all the olives are still green the oil is very aggressive, green with a big acidic hit. Not to my mind very pleasant but I do like the idea.
