Question: are acorns the same as filberts?
Answer: The main difference between Hazelnut and Acorn is that the Hazelnut is a nut of the hazel tree and Acorn is a fruit/nut of the oak tree. ... A filbert is more elongated, being about twice as long as its diameter. The nut falls out of the husk when ripe, about 7 to 8 months after pollination.
