The Science Of Freshness
Freshness is one of the most important indicators of genuine extra virgin olive oil quality, yet it is often overlooked. Unlike many shelf-stable pantry products, olive oil is highly sensitive to time, temperature, oxygen, and light. Preserving freshness requires careful control throughout every stage of production, storage, and bottling.
The journey toward exceptional freshness begins during harvest. At KORAJE, olives are harvested early while still green and at optimum ripeness. This stage naturally provides higher concentrations of antioxidants and polyphenols, along with the vibrant green-fruity aroma associated with premium early-harvest Picual olive oil.
Timing after harvest is equally critical. Once olives are detached from the tree, enzymatic activity and oxidation begin immediately. Delays in milling can negatively affect acidity, flavor, aroma, and nutritional integrity. To minimize degradation, our olives are transported to the estate-owned mill within two hours of harvest, preserving both chemical stability and sensory complexity.
Extraction temperature also influences freshness significantly. While standard cold extraction regulations allow temperatures below 27°C, KORAJE maintains extraction below 21°C. Lower temperatures help retain volatile aromatic compounds and delicate polyphenols responsible for bitterness, pungency, and long-term oxidative stability.
Proper storage remains essential even after extraction. Olive oil is vulnerable to three primary enemies: heat, oxygen, and light. To protect freshness, the oil is filtered, stored in stainless steel tanks under controlled temperatures below 18°C, and protected with nitrogen blanketing to minimize oxidation exposure.
Packaging choices further reinforce preservation. Dark glass bottles help shield the oil from light degradation, while tamper-proof closures help maintain integrity after bottling. Every bottle is labeled with traceable production information, ensuring transparency from grove to table.
Freshness is not simply about flavor. It directly affects authenticity, nutritional value, and the overall olive oil experience. A truly fresh extra virgin olive oil should express balance—vibrant aromas, peppery complexity, natural bitterness, and structural harmony.
At KORAJE, freshness is treated as a measurable quality parameter, not a marketing phrase. Because preserving what nature created requires precision, discipline, and respect at every stage of the process.
