The Picual is an olive cultivar from Spain. Picual olives are the most commonly grown olive today for olive oil production,[1] with production centered in the Spanish province of Jaén.[2] Picual trees are estimated to account for 25% of all olive oil production in the world.[3][4] Naturally, this varietal is very high in oil content, at 20-27% by weight.[5][1]
Virgin olive oil from Picual olives have high levels of polyphenols (an organic compound which is known to have antioxidant effects),[3] typically between 300 and 700ppm.[4] Many Picual groves are primarily harvested when ripe or overripe to maximize oil content, and thus produce oil with poor taste qualities.[5][1] Less than one quarter of the harvest each year qualifies as Extra Virgin.[5]
