Koroneiki
A very small fruit with a disproportionately high and stable oil yield — the combination that made Koroneiki the only Greek variety adopted at scale in mechanised hedgerow orchards around the world. It covers 50 to 60% of Greece’s olive area.
In the grove
Koroneiki is concentrated in Crete and the Peloponnese and forms the basis of most new Greek plantings. It is of medium vigour with a sparse, spreading canopy, roots readily, flowers early, produces abundant pollen and yields high and constant crops with little alternance. It is drought tolerant but cold sensitive, resistant to leaf spot and Verticillium, and very susceptible to olive knot.
Outside Greece it is now one of the three cultivars used in super-high-density orchards worldwide, after Arbequina and Arbosana, and is planted in more than twenty countries. In the largest Greek phenolic dataset — 5,764 oils analysed by qNMR — Koroneiki accounted for 53% of all samples, sitting slightly below the national mean.

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.
