Nocellara del Belice
The variety sold worldwide as the Castelvetrano table olive — and the reason those olives are green rather than black is simply that the fruit stays green at full ripeness. It is one of very few olives that is a first-rank table variety and a serious oil variety at the same time.
In the grove
Nocellara del Belice comes from the Belìce valley straddling Trapani and Agrigento, and is overwhelmingly Sicilian: 98 of 125 samples in Italy’s national monovarietal database came from the island. The tree is of medium vigour, self-sterile, and only moderately productive, but its fruit detaches easily, which makes it genuinely mechanisable. It is susceptible to drought and very susceptible to olive fly, peacock spot and olive knot.
It is the only variety here holding protected status in both product categories: Valle del Belìce DOP for the oil, which requires at least 70% Nocellara, and Nocellara del Belice DOP for the table olives. Do not confuse it with Nocellara Etnea or Nocellara Messinese, which are separate varieties despite the shared name.

Polyphenol figures are the ranges published for each variety, not measurements of any bottle in the library. A single oil's figure depends on when it was picked and how it was milled, and is shown on that oil's own page where the producer states one.
