As mentioned on the Valencian Olive page, Olives are not the tastiest things to grow on trees until cured, pickled or dried, Olive oil though is somewhat easier to produce, squish them. In Valencia the oil is very special, the trees are trimmed to perfection each year and the ground around the trees is weed feed (the leaf less tree in the photo is an Almond, just coming into flower).
When ready the olives are picked gently by hand or with mechanical rakes with rubber fingers so as not to bruise them. Rough handling can raise the acidity in the fruit and you do not want an acidic olive oil. The target is an Acidity of 0.1 acidity and as smooth as silk anything high and it will not get into the extra virgin pressing.
The area of Valencia only produces about 1% of Spain’s Olive oil but what it produces is exceptional. It’s not easy to find outside of the area and most is sold within the communities that produce it but the odd gallon can slip through. On the Coast at Alcosebre, in Castellon Province there’s a street market every Tuesday near the marina and you can often buy some top quality oil straight from the farmer. In some of the smaller village shops the locals bring their own bottles to be filled from a barrel.
Most of the cheap super market olive oils are in green plastic bottles to make the oil look greener in colour. Notice the bottle on the right from the Olistrat co-op of Albocasser, Castellon the glass is clear rather than green so one can see the true colour of the oil.
Tesco are currently doing Spanish Organic extra virgiin Olive oil 500ml for a bargain £2.50. It’s good stuff too (08/04/2016).
