Filbert nuts and hazelnuts are often mentioned in the same breath, leading many to wonder if they are identical. The short answer is yes, but with specific nuances that matter for cooking, nutrition, and agriculture. Filbert is a variety of hazelnut, but the term also refers to the harvest timing and the specific shape of the nut.
Defining Filbert and Hazelnut
To clear up the confusion, it is essential to look at the botanical classification. Both belong to the species Corylus avellana . However, the name "filbert" is traditionally used for nuts where the husk extends beyond the nut itself, resembling a filament or a beard. In contrast, "hazelnut" typically describes varieties where the husk is shorter, leaving the nut more exposed. This distinction is primarily agricultural, separating the late-harvest filberts from the early-harvest hazelnuts.
Flavor and Culinary Uses
When comparing the taste and texture, there is virtually no difference between a filbert and a hazelnut. Both offer a rich, buttery flavor with a slightly sweet undertone and a crunchy texture. Chefs and home cooks use them interchangeably in recipes, from chocolate spreads to baked goods and savory sauces. The roasting process enhances the oil content in both, creating the deep, toasted flavor that makes them a staple in pantries worldwide.
Nutritional Profile
From a health perspective, filberts and hazelnuts are powerhouses of nutrition. They are packed with monounsaturated fats, which support heart health, along with high levels of vitamin E, magnesium, and fiber. Whether you snack on filberts or add chopped hazelnuts to a salad, you are consuming the same dense nutritional package. This similarity makes them an excellent choice for anyone looking to improve their diet with natural, unprocessed foods.
Visual and Textural Differences While the meat of the nut is identical, the physical shell can provide a clue to the variety. Filberts tend to be more elongated and cylindrical, while standard hazelnuts are often more spherical. The husk on a filbert is leathery and thick, fully enclosing the nut until it is ready to be processed. A hazelnut husk is usually thinner and cups the nut rather than wrapping around it completely. These subtle differences help farmers sort the crops but do not affect the kernel inside. Global Production and Naming

The terminology often depends on the region and the language. In the United States, the Oregon hazelnut is the commercial standard, and the term "filbert" was historically used because the harvest coincided with St. Philbert's feast day. In Europe, particularly in Turkey, which produces the majority of the world's supply, the nut is almost exclusively called "hazelnut." The global market prioritizes the flavor and quality of the kernel, so the specific name matters less to the average consumer than the freshness and roast level.
Buying and Storage Tips
Whether you are shopping for filberts or hazelnuts, the selection criteria remain the same. Look for nuts that are heavy for their size, indicating a high meat-to-shell ratio, and have a rich, aromatic smell. Avoid packages with excessive oil on the interior, as this can indicate rancidity. Once home, storing them in an airtight container in a cool, dark place, or even the refrigerator, helps preserve the healthy oils and prevents them from turning bitter.
Conclusion on the Debate
Ultimately, the debate over filbert nuts versus hazelnuts is largely semantic. Botanists and farmers might use the terms to distinguish harvest times and specific cultivars, but for the consumer, they are the same delicious nut. Understanding the subtle differences can enhance your knowledge, but it does not change the fact that both provide the same versatile ingredient for countless culinary creations.
