Galega Vulgar
Portugal’s dominant traditional variety by tree count — about 60% of the country’s olives — and one of its lowest yielding. Under 18% oil from fruit weighing less than two grams is precisely why it is being replaced in new intensive plantings.
In the grove
Galega grows across Beira Interior, Ribatejo, Alentejo and the Algarve, and is also reported in Spain. It is rustic and drought tolerant with marked alternate bearing, but sensitive to cold, salinity and active limestone. It is resistant to Verticillium and very susceptible to anthracnose — the disease Portuguese growers call gafa — as well as to olive fly and olive knot.
Its agronomic problem is compound. Fruit under two grams, a poor flesh-to-stone ratio, oil yield below 18%, and a tree poorly suited to both trunk-shaker harvesting and high-density systems, giving 3 to 5 tonnes per hectare where foreign varieties in intensive orchards give 8 to 13. There is a quality consequence too: research shows anthracnose-infested Galega fruit loses phenolic content, so the oil’s compliance with the EU health claim depends on disease control, not on the variety alone.

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.
