Polyphenols: The Science Behind Soma Grove
Our mountain Koroneiki olives produce a naturally polyphenol-rich oil — certified high phenolic every harvest, and fully transparent with lab analysis so you know exactly what's in the bottle.
Chemical Analysis Overview
Ultra-Low Acidity
- 0.24%
- Significantly below the strict international standard of 0.8% for extra virgin olive oil
- Indicates an extremely fresh and high-quality oil, free from defects and improper processing
Abundant Health-Boosting Compounds
- Oleocanthal + Oleacein: Responsible for the oil's distinct peppery taste and known for powerful anti-inflammatory effects.
- Hydroxytyrosol + Tyrosol: Recognized by the European Food Safety Authority for their role in protecting blood lipids from oxidative stress.
Polyphenol Count
- Total Polyphenols: 785 mg/Kg
- This high concentration of polyphenols far exceeds the threshold of 250 mg/kg needed for a health claim
- A significant portion of this total is made up of powerful compounds like oleocanthal, oleacein, and their potent cousins, tyrosol and hydroxytyrosol
The Altitude Difference
Higher Phenolic Density
Olive groves at mountainous levels, such as those in Zakynthos, have been scientifically proven to produce oil with significantly higher total phenolic content compared to lowland or coastal areas.
Superior Antioxidant Activity
Research indicates that mountainous altitude levels are positively correlated with increased antioxidant activity and radical-scavenging potential.
Unique Aromatic Compounds
Mountainous oils contain specific volatile compounds, such as the terpene (E,E)-α-farnesene, which are entirely absent in lower-altitude coastal oils, contributing to a more complex and "wild" flavor profile.
Rich in Oleocanthal & Oleuropein
Supports heart health, healthy inflammation response, cognitive function, and skin vitality from the inside out.
Enhanced Chlorophyll Content
High-altitude samples record the highest levels of chlorophyll, a natural pigment that contributes to the oil's deep green color and offers additional antioxidant value.

Scientific Analysis of Mountain Groves
Not all Koroneiki olive oils are equal. Soma Grove is sourced from the mountainous 'Level A' regions of Zakynthos, with elevations ranging from 300 to 500 meters above sea level. Scientifically verified by the University of Ioannina, our high-altitude environment produces a more potent, antioxidant-dense oil with a unique chemical fingerprint not found in coastal or lowland groves.
| SOMA GROVE (Mountainous) | Lowland & Coastal Oils |
|---|---|
| Altitude Level | |
| Level A: High-Altitude (Agios Leon) sitting at ~380m+ [cite: 50, 65] | Levels B & C: Lowland/Coastal ranging from 6m to 179m [cite: 50, 65] |
| Total Phenolic Content (TPC) | |
| Highest recorded: 102.25 mg GAE/kg | Significantly lower: 60.06 – 90.59 mg GAE/kg [cite: 196] |
| Chlorophyll (Pigment Quality) | |
| Highest Level: 8.74 mg PE/kg — yielding a deep, high-quality green | Lower Levels: 5.99 – 6.45 mg PE/kg [cite: 218] |
| Antioxidant Activity (DPPH) | |
| Superior Performance: 35.59% radical scavenging inhibition [cite: 182, 197] | Moderate Performance: ~22.87% – 23.09% inhibition [cite: 182, 197] |
| Unique Aromatic Profile | |
| Presence of (E,E)-α-farnesene; exclusive to mountain samples | Absence of specific mountainous terpenes |
| Purity & Acidity | |
| Ultra-low acidity (~0.32%), far below the 0.8% EVOO limit [cite: 182, 433] | Coastal samples recorded acidity nearly 2x higher than inland samples [cite: 171, 182] |
