Biodiversity and innovation for top quality extra virgin olive oils

The OLIONOSTRUM extra virgin olive oil was born in the heart of central Tuscany, more precisely in the municipality of Bucine in the Valdambra, on the border between the provinces of Arezzo and Siena.

It is the result of the selection of the best olives coming exclusively from the olive growers of this area who in 2020 created the Agricolae Oleum network.

The olives are processed in the Olivone oil mill (link to the oil mill page), an innovative high-tech plant. It is a prototype designed and built exclusively for the Agricolae Oleum network in order to obtain the highest quality and typicality from the local varieties.


A delight for the senses

Discover the unique aroma and taste of the native olive varieties of the municipality of Bucine and the Valdambra.

Medium-high intensity of fruitiness. The hints on the nose are green with marked notes of grass and salads but also of olive leaf, artichoke and green tomato. In the mouth, the scents of the nose are confirmed with more artichoke nuances and the appearance of green almonds, the bitterness and spiciness are balanced and quite intense, as is typical for the oils of the area. A very pure and complex oil that reflects the work and passion of all the actors in this project.
For the ideal pairings we want everyone to look for them following their own creativity, to experiment and play with the dishes they prefer, creating their own best pairings.


Light is the main enemy of a quality oil, which is why the glass has been enhanced so as to make the OLIONOSTRUM bottle impenetrable to light rays. The two colors that fade from lime green to purple are not accidental, they represent the change in color that the olive undergoes when it begins to ripen. This process is called veraison and to obtain oils of the highest quality it is first of all necessary to harvest the olives early, generally in the month of October. Our bottle evokes a process full of attention and care, a process of transformation that starts from the raw material, the fruit.

At the heart of the Olionostrum project are the local varieties, discovered and identified in the olive groves of the municipality of Bucine and the Valdambra by the researchers of the CNR-Ibe of Florence, who have identified well over 40 genotypes of unique olive trees, testifying to the extraordinary biodiversity of this area.

Faced with this important discovery, the municipality of Bucine considered it necessary to commit itself to the preservation of these autochtonous native olive varieties, launching the OLIONOSTRUM project with the aim of characterizing its production of oil by milling and extracting only local cultivars.

It is therefore thanks to the collaboration between the municipality of Bucine, the University of Florence DAGRI, the CNR National Research Center IBE and the olive growers of the Agricolae Oleum network that these unique cultivars, that would otherwise have risked extinction, have been saved.


OLIONOSTRUM is the fruit of the assembly of the best pressings obtained by the producers of the Agricolae Oleum network of growers, exclusively from olives harvested in the Municipality of Bucine and pressed with innovative extraction technologies developed in the Olivone olive mill.

To bear the OLIONOSTRUM brand, the oil is examined and judged by a panel of professional tasters who verify and decree its quality every year.

OLIONOSRUM is the demonstration of the ability of farmers and producers and the local community to join forces with the aim of giving olive growing and extra virgin olive oil the full value and recognition they deserve.

The collection of Valdambra olive trees

The more than 40 genotypes of the Valdambra olive trees are preserved and studied in the germplasm collection facility, created by the municipality of Bucine in collaboration with
the CNR IBE of Florence in the Villa a Sesta farm.

The objective is the characterization of the phenotypes for which the surveys are carried out aimed at collecting the morphological and bio-agronomic data necessary for the description and registration of the new native Valdambra cultivars in the olive repertoires of the Region of Tuscany.

The various olive varieties that were discovered did not have a name to help identify them, and it was decided to do so and many names refer to the name of the owner or farm so as to pass on their memory to future generations of olive growers.
