The Impact of Harvest to Production Time on Olive Oil Quality
Consumers are becoming increasingly aware of the critical time window between olive harvest and oil production. Experts recommend that this period should not exceed a few hours to maintain the oil’s freshness and phenolic content, key indicators of quality.
In California, known for its modern methods, producers plant dwarf olive trees close together for quick machine harvesting. Meanwhile, Kiara Koutoulakis of Koronekes in Crete emphasizes similar speed for handpicked olives. “The fresher the olives, the better the oil,” she asserts, noting the fragility of olives as fruits and their highest phenolic levels before turning black.
Pressing Techniques: First Cold Press vs. Centrifuge
Small producers like Koronekes utilize terms like “first cold press” to denote a richer flavor and quality levels, employing traditional pressing techniques. In contrast, larger producers often opt for centrifugal extraction, foregoing such labels.
Storing Olive Oil: Enhance Its Longevity
Once at home, the clock starts ticking for olive oil usage. Selina Wang advises treating olive oil vierge extra like a perishable item, suggesting a maximum usage period of four months post-opening. Storage away from heat and light and limiting exposure to air during use are crucial for preserving its phenols.
Price and Global Challenge
The future price of olive oil is uncertain due to environmental challenges like floods, wildfires, and droughts. Investing in fresh oil when prices are relatively low is advisable, but storage can help extend shelf life. “Avoid repetitive temperature changes to prevent taste and appearance alterations,” warns Wang, recommending keeping the oil in a cool, dark place or frozen if unopened for extended periods.
