Cold Pressing vs. Cold Extraction: Key Differences

Cold pressing and cold extraction are two methods for producing extra virgin olive oil (EVOO). While both keep temperatures below 27°C to protect oil quality, they differ in process and outcomes:

• Cold Pressing: Uses traditional hydraulic presses to extract oil. It’s less efficient, harder to control for quality, and has higher contamination risks.
• Cold Extraction: Relies on modern centrifugation, offering better hygiene, higher yields, and consistent quality. It preserves more nutrients and flavors.

Cold extraction is now the preferred choice for modern EVOO production, ensuring better quality and flavor preservation.

How is Olive Oil Produced? Part 2: Cold Extraction

The Cold Pressing Method

How Cold Pressing Works

Cold pressing is one of the oldest techniques for extracting olive oil. It starts by grinding olives into a paste using stone mills. This paste is then pressed using hydraulic pressure applied to fiber mats, squeezing out the liquid. The extracted liquid is left to settle, allowing the oil to naturally separate from water due to their different densities ^[1][3].

A Glimpse Into Its History

The method has deep roots in olive oil production. The phrase "first cold press" comes from this traditional approach, where the first pressing produced the best-quality oil. Later pressings, often done with hot water, resulted in oils of lower quality ^[3].

Drawbacks of Cold Pressing

While cold pressing has historical importance, it comes with several challenges in today's olive oil production:

This batch-based method is less productive compared to modern continuous systems ^[3]. These drawbacks have led the industry to adopt cold extraction, a more efficient and controlled process that is now the standard ^[1][3].

The Cold Extraction Method

How Cold Extraction Works

Cold extraction is a modern approach to producing olive oil that keeps temperatures below 27°C during the entire process. This method uses advanced centrifugation to separate the oil from crushed olives, ensuring the oil retains its quality and flavor ^[2][4]. The process starts with crushing olives into a paste, followed by malaxation (mixing the paste), and then centrifugation to extract the oil - all while carefully controlling the temperature.

Why Cold Extraction Stands Out

Cold extraction has become a preferred method for olive oil production due to its many advantages:

These factors make cold extraction the go-to method for producing high-grade extra virgin olive oils.

The Industry’s Choice

Today, top olive oil producers rely on cold extraction to meet strict European food regulations and deliver exceptional quality. This method is celebrated for preserving delicate compounds, adhering to temperature requirements, and ensuring consistent results ^[3][4].

For anyone looking for premium extra virgin olive oil, cold extraction is key. By keeping temperatures below 27°C, this process protects the compounds that enhance the oil's flavor and health properties ^[4].

Comparison of Cold Pressing and Cold Extraction

Key Process Differences

Cold pressing relies on traditional hydraulic presses, while cold extraction uses modern centrifugation techniques. Both methods maintain temperatures below 27°C, but cold extraction represents a leap forward in olive oil production, transforming how premium oils are made.

Quality Impact and Benefits

Cold extraction outperforms cold pressing by preserving more of the oil's natural taste and aroma. This method ensures oils are fresher, more flavorful, and retain essential nutrients ^[2][3]. Its controlled process also delivers consistent quality, particularly excelling in:

• Preserving antioxidants
• Retaining natural flavors
• Maintaining freshness
• Meeting higher hygiene standards

"Thanks to modern production systems, the current extraction process is superior in all aspects to the traditional one, which allows 'cold extraction' extra virgin olive oils to have greater organoleptic properties than 'first cold pressed' oils." - Oleoestepa ^[3]

Conclusion

Key Takeaways

The transition from cold pressing to cold extraction has transformed olive oil production. Cold extraction not only preserves flavor, aroma, and nutrients but also ensures a cleaner and more efficient process ^[1][3]. This method has effectively replaced the older "first cold press" terminology, which is now considered outdated ^[6].

Modern mills have embraced centrifugation to maintain the integrity of the oil, showcasing the industry's emphasis on quality ^[3]. Knowing these production methods empowers consumers to make smarter choices when purchasing olive oil.

How to Spot Quality Olive Oil

Here are some key factors to look for in high-quality olive oil:

To find the best olive oil, look for products made using cold extraction and backed by certifications. Check for details like harvest dates, best-by dates, and the country of origin to ensure freshness and authenticity ^[6].

Brands like Big Horn Olive Oil highlight how modern cold extraction techniques can produce oils that retain both nutritional value and rich flavor. Their dedication to this method guarantees customers enjoy the freshest and highest-quality extra virgin olive oil available.

FAQs

What is the difference between cold press and cold extraction?

Cold pressing involves using hydraulic presses to extract oil from olive paste, while cold extraction uses modern centrifugation technology for improved efficiency and precision ^[1]. The cold extraction method allows for better temperature regulation and reduces contamination risks thanks to its enclosed system ^[3].

Is cold extracted olive oil better than cold-pressed?

Both methods can produce excellent olive oil when done correctly. However, cold extraction generally offers more control, higher efficiency, and consistent quality compared to cold pressing ^[3].

Both processes must keep temperatures below 27°C to maintain the oil's quality ^[2]. That said, cold extraction provides better control over temperature, hygiene, and quality consistency, making it the go-to choice for modern olive oil production ^[3][5]. Many top producers, like Big Horn Olive Oil, rely on cold extraction to produce premium extra virgin olive oils.
