ORO CELESTE's Three Single-Cultivar Oils Measure 0.14–0.20% Acidity — About a Quarter of the EVOO Limit
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.

ORO CELESTE has printed the measured acidity of each of its three single-cultivar oils directly on the label. Sibarita registered 0.14%, Ojiblanca 0.16%, and Picual 0.20%. The International Olive Council (IOC) sets the acidity ceiling for extra virgin olive oil (EVOO) at 0.8%, meaning all three cultivars came in at roughly one quarter of that threshold.
Acidity as a Measure of Freshness
Acidity in olive oil is not a flavour descriptor — it measures free fatty acid content. According to the IOC, when olives are harvested late or when oxidation occurs during transport and storage, that figure climbs. It is for this reason that acidity has become a primary indicator of both freshness and grade. Under IOC classification rules, any oil exceeding 0.8% free acidity loses its extra virgin status and is reclassified as virgin or refined grade.
The Process Behind the Numbers
ORO CELESTE states that harvested olives are pressed on the same day they are picked, with no refining step before bottling. The brand reports an average window of under 12 hours from harvest to pressing, and an average pressing temperature at or below 27 °C. Because there is no refining, blending, or reprocessing stage, the opportunity for oxidation is correspondingly reduced, according to the brand. Acidity is measured for every batch, so the figure printed on the label matches the reading in the third-party test certificate accessible via the QR code on each bottle.
Frequently asked questions
- What does acidity percentage mean in olive oil?
- Acidity in olive oil refers to the proportion of free fatty acids, not a taste sensation. It rises when olives are harvested late or exposed to heat, damage, or prolonged storage. According to the International Olive Council (IOC), an oil must measure 0.8% acidity or below to qualify as extra virgin.
- How do ORO CELESTE's acidity numbers compare to the EVOO standard?
- The IOC sets the extra virgin grade ceiling at 0.8% free acidity. ORO CELESTE's three single-cultivar oils measured 0.14% (Sibarita), 0.16% (Ojiblanca), and 0.20% (Picual) — each roughly one quarter of that upper limit.
- Why does same-day pressing affect acidity?
- Once olives are harvested, enzymatic activity and oxidation begin to raise free fatty acid levels. Pressing within hours of harvest, as ORO CELESTE states it does — averaging under 12 hours from grove to mill — limits the time available for that process, which is associated with lower acidity readings.

- The 0.16% on Your Olive Oil Label Has Nothing to Do With Sourness
The acidity figure printed on an extra virgin olive oil label is not a measure of sour taste — it is a chemical indicator of free fatty acid content that reflects the condition of the fruit before and after pressing.
