Hazelnuts are harvested in late summer to autumn, when the nuts have reached their full size, the shell has turned brown and the leaves of the hazelnut bush are beginning to turn yellow. Harvesting machines are used to shake the trees and collect the fallen nuts. After harvesting, the hazelnuts are cleaned and dried thoroughly to prevent mold growth. The nuts are then cracked by machine so that the kernels can be removed from the shells and the pure nut meat extracted. The shelled hazelnut kernels are processed in a cold press. In this mechanical process, the oil is extracted from the nuts without heat and without the use of chemicals. This preserves the natural aromas and nutrients of the hazelnuts. A final filtration removes natural suspended particles and ensures a high-quality oil of exceptional quality. Final laboratory analyses in our own DIN ISO 17025-certified laboratory confirm the high degree of purity and quality, which is highly valued in the food and cosmetics industry in particular. NATRUE certification confirms the authenticity and naturalness of our refined hazelnut oil.
