DOP Umbria — Colli del Trasimeno

DOP Umbria Certification

Protected Designation of Origin - Colli del Trasimeno

VerdePaciano holds the DOP Umbria - Colli del Trasimeno certification. This EU designation ties our oil to a specific geographic area and requires compliance with strict production standards.

Our DOP Olive Varieties

The DOP Umbria Colli del Trasimeno certification recognizes four olive varieties. We grow all four.

What is DOP?

DOP (Denominazione di Origine Protetta) is the Italian equivalent of PDO (Protected Designation of Origin), a European Union certification that protects and promotes agricultural products whose characteristics are essentially or exclusively due to their geographical environment. For olive oil, DOP certification ensures that every stage of production—from cultivation to bottling—takes place within a specific region using traditional methods.

Colli del Trasimeno Designation

The Colli del Trasimeno area encompasses the hills surrounding Lake Trasimeno in Umbria, central Italy. This unique microclimate, characterized by mild temperatures and optimal sun exposure, creates ideal conditions for cultivating exceptional olive varieties. The lake's thermal regulation protects the groves from extreme temperatures, contributing to the oil's distinctive flavor profile.

Quality Standards & Criteria

To earn and maintain DOP certification, our oil must meet rigorous chemical and organoleptic requirements:

Maximum Acidity

≤ 0.65%

Free fatty acids (expressed as oleic acid per 100g)

Polyphenol Content

≥ 100 mg/kg

Antioxidants contributing to health benefits and flavor

Oil Yield

≤ 17%

Maximum olive-to-oil extraction rate per DOP regulations

Harvest Deadline

December 31

Olives must be harvested directly from trees by this date

Maximum Yield per Hectare

≤ 6,500 kg/ha

For intensive olive grove plantings

Organoleptic Characteristics

Color

Green to golden yellow

Aroma

Light to mild fruity

Flavor

Fruity with slight hints of bitterness and piquancy

Packaging Requirements

Official DOP regulations for consumer packaging

Maximum Container Size

≤ 5 Liters

DOP certified oil must be sold in containers no larger than 5 liters

Permitted Materials

Glass or Tin Plate

Only glass bottles or tin plate containers are permitted for DOP certification

Understanding Quality Indicators

Professional olive oil tasters use specific terminology to describe quality. Here's what these terms mean:

Fruity (Fruttato)

The fresh aroma of olives. This is what tasters check for first. No fruitiness means the oil has degraded or was poorly made.

Bitter (Amaro)

A taste from green olives that signals high polyphenol content. Most people assume bitterness is a defect, but in olive oil it is the opposite.

Pungent (Piccante)

The peppery, throat-catching sensation from fresh oil. Caused by oleocanthal. The International Olive Council uses this as an official quality indicator.

Peroxide Value

Measures oxidation levels. Lower values mean fresher oil. DOP limit is ≤ 20 meq O2/kg; ours stays well below 6.

Our Certified Analysis

Analysis conducted by certified laboratory. Values shown are from actual lot samples.

The 2025 harvest produced two lots: AL01, picked early with very high polyphenols (566 mg/kg) and sharp freshness, and B24, picked a week later with a rounder taste and slightly lower but still strong polyphenols (482 mg/kg). Both are well above DOP Umbria minimums.

International experts use these spectrophotometric values (K232, K270, ΔK) to measure oil purity and oxidation levels. Lower values indicate superior quality and freshness.

Traditional Production Methods

DOP certification requires adherence to traditional production methods that have been refined over centuries. Our process includes hand-harvesting or gentle mechanical harvesting directly from the tree, immediate transport to the mill (within 24 hours), cold extraction at temperatures below 27°C, and natural decantation without chemical filtration. Every step is designed to preserve the oil's nutritional properties and authentic flavor.

Traceability & Authenticity

Each bottle of VerdePaciano DOP Umbria - Colli del Trasimeno carries a unique identification code that traces back to the specific harvest, grove location, and production date. This complete traceability system, mandated by DOP regulations, guarantees authenticity and allows consumers to verify the origin and quality of their oil.
