Olive Harvesting Process
In Ribatejo, harvesting is a careful blend of timing and technique, combining both traditional methods and modern tools to produce high-quality olive oil.
When to Harvest
Producers closely observe several factors to determine the perfect time to harvest. These include:
- The shift in olive color from green to purple
- The development of oil content within the fruit
- Current weather conditions
- Historical trends for specific olive varieties
Once the timing is decided, the focus shifts to selecting methods that protect the olives from damage during harvest.
Harvesting Methods
Both traditional and modern approaches are used to uphold quality during harvest. For the finest olives, many producers prefer hand-harvesting, as it allows for careful selection and minimizes damage. In larger groves, specialized equipment comes into play, such as:
- Mechanical tree shakers equipped with catching frames
- Hand-held branch shakers for smaller trees
- Protective nets to catch falling olives
These techniques ensure the olives remain intact and are swiftly transported for processing, which is crucial for maintaining oil quality.
Post-Harvest Care
Handling olives properly after harvest is critical to preserving their freshness before processing. Producers act quickly, moving the olives to processing facilities within hours to prevent quality loss.
Standard post-harvest practices include:
- Using shallow, ventilated crates for storage
- Keeping olives in cool, shaded conditions
- Sorting out any damaged fruit
- Ensuring processing begins within 24 hours of harvest
These steps guarantee that only the best olives make it to the extraction process, contributing to the exceptional quality of Ribatejo olive oil.
Oil Extraction Steps
In Ribatejo, time-honored methods blend with advanced technology to turn carefully selected olives into high-quality olive oil. After a quick post-harvest process, the olives move to the mill for extraction.
Mill Preparation
At the mill, freshly harvested olives are inspected and sorted to remove leaves, twigs, and any damaged fruit. They are then gently washed to clean off impurities while protecting their natural properties.
Cold Extraction Process
The cold extraction method helps retain delicate flavors and natural compounds. Here’s how it works:
- The olives are crushed into a paste.
- The paste is gently mixed (a process called malaxation) to combine oil droplets.
- Oil is separated from water and solid components.
Temperature is carefully controlled during each step to avoid overheating, which could affect the oil's quality. After extraction, specialized equipment is used to refine the process further.
Processing Equipment
While some producers continue to use traditional stone mills, modern systems allow for real-time adjustments, ensuring consistent results and precise quality management.

Final Production Stages
Oil Purification
To separate oil from water and sediment, producers use advanced filtration systems under tightly controlled temperatures. These systems remove even microscopic particles while preserving the oil’s natural qualities. This process plays a key role in achieving the high smoke point - typically 410°F or higher - that premium extra virgin olive oils are known for. Once purified, the oil is stored in ideal conditions to maintain its quality until it’s ready for bottling.
Storage Methods
After purification, maintaining freshness is crucial. In Ribatejo, producers rely on stainless steel tanks with controlled environments to protect the oil from its biggest enemies: light, heat, and oxygen. These tanks are temperature-regulated and filled to reduce air exposure, ensuring the oil stays fresh.
Even with proper storage, olive oil naturally degrades over time. Producers monitor the storage period closely and track the crush date of each batch. For the best flavor, they recommend consuming the oil within 9 months of production.
Quality Control
Strict quality control ensures only the best olive oil makes it to market. Testing includes the following standards:
| Test Parameter | Quality Standard |
|---|---|
| Smoke Point | 410°F or higher |
| Oil Purity | 100% extra virgin olive oil (EVOO) |
| Grade Selection | Top 5% of olive harvests |
| Freshness Window | Best within 9 months of crush date |
Each batch undergoes detailed analysis for chemical composition and sensory attributes. Oils that meet these rigorous standards are certified for sale. Regular testing during storage ensures the oil retains its premium qualities until bottling. This dedication to quality helps Ribatejo producers deliver olive oil that stands out for its exceptional flavor and characteristics.
