Science that proves the difference
EARLY HARVEST
The olives are picked early, when they have the most healing power and are still green. This is followed by a quick, cold extraction in less than 24 hours, which is key to maintaining quality. The result is an extremely low acidity (0.2-0.4%), which is well below the EU standard (0.8% for EVOO), ensuring that the oil remains fresh and stable for much longer.
BITTERNESS = HEALTH AND POLYPHENOLS
The original bitterness and spiciness are not a defect, but a natural antioxidant shield. This taste is a testament to the exceptional freshness and high content of polyphenols (typically 450-600 mg/kg), which are essential for your health. The European Food Safety Authority (EFSA) confirms that polyphenols help protect blood lipids from oxidative stress.
Tested in the lab and with the senses
Laboratory tests confirm the oil's freshness and the strength of its antioxidant shield, and a sensory panel verifies it to be flawless. Bittergreen contains exceptionally high levels of polyphenols – two to three times more than the average extra virgin oil. These natural antioxidants protect cells and contribute to heart health.
Low acidity further confirms proper processing and stability: less degraded fats, more shelf life and a flavor that remains alive even weeks after opening. Our values are well below the official limit for extra virgin oil – scientific and sensory proof that every bottle is truly fresh.
DOUBLE GUARANTEE: IGP TOSCANO & ORGANIC
Authenticity is based on two certificates that prove the truth in every bottle. IGP Toscano is a legal guarantee of origin: the olives are grown and pressed exclusively in Tuscany, and each batch is confirmed by a laboratory test and a sensory taste evaluation. The EU organic certificate guarantees production without pesticides, herbicides and compromises.
Authenticity you can follow
Every bottle of Bittergreen has its own digital passport. We believe that authenticity and quality are the foundation of every great experience. Our commitment to science means that every step – from selecting the finest Tuscan olives to pressing and packaging – is backed by evidence of nutritional value and aromatic perfection.

Lower acidity means better quality, greater freshness and a higher content of health-promoting compounds. While the standard for extra virgin oil is 0.8%, Bittergreen oil ranges from 0.10 to a maximum of 0.45%.
Yes. There is a code on each bottle that you can use to check the production location, harvest, and certifications.
Olive harvesting begins in early October, when they contain the most antioxidants. The yield is lower, but the quality, taste and nutritional value are significantly higher.
Bitterness and spiciness are signs of quality – they indicate a high content of polyphenols, which act as natural antioxidants. If the oil "burns in the throat", it means that it is really fresh and rich in medicinal compounds.
Think of polyphenols as the vitamins of olive oil, they keep the oil alive, while also keeping the cells alive.
When you feel that slight 'burning' sensation in your throat, that's polyphenols at work — proof that the oil is fresh and full of life.
For optimal taste and effect, we recommend using within 12-18 months of bottling. As this is a fresh product, store it in the dark and at room temperature.
