 C. maxima is more sensitive to cold than C.avellana. Their main growing area is located in the Turkish Black Sea region, where three-quarters of the world's produced commercially available "hazelnuts" are produced.  C. maxima is more sensitive to cold than C.avellana.

 +Volatiles of hazelnut oil (Turkey, cold-pressed from roasted seeds) were characterized by high amounts of acetic acid (33.7%), 3-methylbutanal (19.1%), 2-methylbutanal (14.0%), and hexanal (3.3%). Compounds with known impact on roasted notes were 2-methylpyrazine (3.2%), furfural (2.3%), furfurylalcohol (0.5%), dimethylpyrazines (4.4%), γ-butyrolactone (1.1%), and benzaldehyde (0.7%). \\
