Royal de Cazorla
A mountain variety that survives as a six per cent minority inside a Picual monoculture, kept alive by its aroma rather than its yield. Royal gives less oil than Picual and measures higher in volatile compounds than any of the major Spanish cultivars.
In the grove
Royal grows in the Sierra de Cazorla and the natural park of Sierras de Cazorla, Segura y Las Villas — some 70,000 hectares of mountain country where Picual takes 94% of the ground and Royal about 6%. Five cooperatives certify roughly 400,000 kilos of Royal oil a year. The tree flowers earlier than its neighbours but ripens later, is vigorous and consistently productive, and has notably brittle wood.
One peer-reviewed study measured mill-extracted Royal at 74.9% oleic acid and 156 mg/kg total phenols under specified processing conditions, with volatile compounds at 18.98 mg/kg — higher than Picual, Arbequina, Koroneiki or Arbosana in the same work, dominated by C6 aldehydes. That is the trade in one line: less oil, less bitterness, more aroma.

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.
