Notes on olive oil & taste
Polyphenol levels in extra virgin olive oil can vary by a factor of ten or more depending on cultivar. This data-driven guide compares the polyphenol content and flavor profiles of three benchmark varieties: Greece's Koroneiki and Spain's Picual and Arbequina.
ORO CELESTE's 2025 harvest brought three early-picked extra virgin lines — Ojiblanca, Sibarita, and Picual — each with its own acidity, polyphenol count, and sensory profile. Tasted side by side, the differences between cultivars grown in the same region and the same season are striking.
The best-by date on an olive oil bottle assumes it has never been opened. Once air gets in, oxidation begins immediately — and how fast it progresses depends on polyphenol content, storage temperature, light exposure, and container type.
ORO CELESTE Picual's certificate of analysis carries a notation that its polyphenol reading exceeded the instrument's quantification limit. Here is a calm, precise look at what that number means in the context of olive oil quality.
Acidity and polyphenol numbers set the baseline, but the IOC's six-point sensory evaluation is where an EVOO's personality actually shows. This guide walks through every criterion—color, aroma, taste, pepperiness, balance, and finish—across ORO CELESTE's Ojiblanca, Sibarita, and Picual expressions.
While most producers wait for full ripeness, ORO CELESTE times three separate harvests in early November — catching Ojiblanca, Sibarita, and Picual at the narrow window when polyphenols peak and acidity is at its lowest.
The temperature at which olives are pressed determines how much flavor and polyphenol content survives into the bottle. This guide examines why 27°C is the regulatory and sensory threshold that separates genuine cold-press olive oil from ordinary extraction.
ORO CELESTE's Picual registers an acidity of 0.20% and polyphenols above 800 mg/kg — figures that push standard laboratory instruments to their measurement limits. This guide examines what those numbers mean and why this oil's peppery finish is in a category of its own.
ORO CELESTE's Ojiblanca registers 0.16% acidity and more than 600 mg/kg polyphenols — numbers that frame a flavor profile built in three distinct layers, from green-apple aroma to a gently peppery close.
ORO CELESTE has published certified lab figures for three single-varietal extra virgin olive oils directly on labels and its official website. Picual tested above the instrument detection limit at 800 mg/kg or more; Ojiblanca and Sibarita came in at 600 mg/kg or more and 500 mg/kg or more, respectively.
ORO CELESTE has printed the measured acidity of each of its three single-cultivar oils directly on the label. The figures — Sibarita 0.14%, Ojiblanca 0.16%, Picual 0.20% — sit well below the International Olive Council's 0.8% ceiling for extra virgin classification.
Acidity alone does not determine olive oil quality. When an IOC sensory panel detects a defect at tasting, even an oil below 0.8% acidity can be downgraded from extra virgin status.
