Although the European Union has issued precise guidelines on its quality designation, these are often circumvented.

Olive oil is available in an unusual range of flavors. There are very mild oils with a delicate aroma reminiscent of bananas (mostly from Greece) and very strong Spanish oils that already oscillate into bitterness. In between everything is possible.
