Hazelnut trees are part of the birch family. Native to the north temperate zone, they are also cultivated today in some areas in the south temperate zone.
The scientific name of the world's most commonly cultivated hazelnut species is Corylus avellana. The name Corylus comes from the Greek ‘korys’ (helmet), a reference to the calyx covering the nut. Avellana references the ancient city of Abella (currently the city of Avella in Campania, Italy). One of the earliest mentions of hazelnuts has been found in a Chinese manuscript dating to 5,000 years BC. Hazelnuts played an important role in ancient Roman culture and in his poem about agriculture, "Georgics", the classical poet Virgil mentions the particular expertise needed in growing hazelnuts.
Hazelnuts are a versatile ingredient
available in many forms from raw, roasted or ground into a paste. As well as having a rich, premium and distinctive taste, they also have a positive nutritional role thanks to their antioxidants and micronutrients.
Hazelnut orchards can be found all around the world, mainly in Mediterranean-type climates
Hazelnut trees can take up to six to eight years to mature, but they can live for a very long time. The hazelnut tree is perennial (producing a crop each year without being replanted), with a height of 2-6 metres. The life cycle of this bushy plant goes through several stages before it becomes the nut that goes into many Ferrero products. Each plant produces female flowers, which are red and feathery; and long, yellow male flowers.
During winter, the wind carries the pollen from the male to female flowers, however, as hazelnut trees cannot pollinate themselves, orchards are typically laid out so the trees can pollinate each other. After pollination, the hazelnuts start to form and are ready for harvest in the late summer and early autumn. As a perennial crop the hazelnut tree has a permanent root structure. This means that in comparison with a crop which completes its whole life cycle in a single growing season (annual crop) it is more efficient in preventing soil erosion and limiting excessive water runoff. The root systems of perennial crops preserve soil humidity throughout the year.
Scientific studies have also shown that hazelnut orchards have a favourable potential for carbon sequestration, which means that they capture carbon dioxide from the atmosphere through photosynthesis and other biological processes. Carbon sequestration is common in all tree species, including fruit trees. Among fruit trees, hazelnuts are particularly beneficial from a carbon sequestration perspective due to the long growing cycle of an average orchard.
Different hazelnut varieties are suitable for different growing regions and they also have different organoleptic profiles.
There are more than 300 hazelnut varieties, and each is distinctive. For example, elongated types can be used in hazelnut pastes and rounded types are better for pralines. When blended with chocolate, the hazelnut accentuates the taste experience whilst still retaining its particular characteristics.
Our hazelnuts come from different parts of the world, the main origins are Turkey, Italy, Chile and the USA.
As part of our commitment to ensure a high-quality and fresh supply of hazelnuts throughout the year, we are involved in hazelnut cultivation in both the northern and southern hemispheres.
Turkey is an important sourcing country with a long history of hazelnut cultivation, as its Black Sea region is the world’s largest producer of hazelnuts.
Our expertise and tradition with this fruit also goes back to our roots in Italy, as hazelnuts are also grown in the Piedmont region - where Ferrero was founded - as well as in the regions of Lazio and Campania.
The northern hemisphere harvest takes place between the beginning of August and the end of September.
To ensure year-round availability of quality and fresh hazelnuts
cultivation also takes place in the southern hemisphere, providing an additional harvest from February to March. As part of this approach, we have established our own Agrifarms in countries such as Chile where traditionally hazelnut cultivation has not been significant.
We also source hazelnuts from Oregon in the USA. Oregon has a long and well-established tradition and expertise in hazelnut cultivation.
