The Dominance of English Walnuts
The English walnut, Juglans regia, is the most prevalent variety available in grocery stores globally and is the one most consumers picture when they think of a walnut. Originally from Persia, this walnut has been selectively bred over centuries for its desirable characteristics, including a mild flavor and a thin, easy-to-crack shell. Its broad appeal makes it a staple for snacking, baking, and cooking. Within the English walnut category, some stores may carry specific cultivars like the 'Chandler,' which is prized for its attractive light amber color and easy-to-remove kernel. Most shelled walnuts, sold as halves and pieces in bags, are also English walnuts.
Why English Walnuts Are the Grocery Store Standard
- Mild Flavor: The pleasant, buttery taste is versatile and appeals to a wide range of palates, making it suitable for numerous recipes.
- Thin Shells: Their easy-to-crack shells make them a convenient option for home use.
- High Yield: Commercial breeding has maximized the amount of edible nutmeat, providing more return on investment for producers and better value for consumers.
- Efficient Processing: Their structure allows for efficient mechanical shelling, a critical factor for large-scale commercial production.
The Strong, Earthy Flavor of Black Walnuts
Black walnuts, Juglans nigra, are native to North America and are known for their distinctively bold, earthy, and sometimes musty flavor. They are far less common in standard grocery store aisles for several reasons. Their shells are significantly thicker and harder to crack, often requiring special equipment. Furthermore, the husks contain a substance that can stain hands, and the nutmeat-to-shell ratio is much lower than in English walnuts. If found, they are typically sold in smaller, specialty packages and are often more expensive. Because of their intense flavor, they are often favored by bakers for specific recipes, like fudge and ice cream, where the strong, nutty taste can hold its own.
Other, Rarer Walnut Varieties
While English and Black walnuts dominate the market, very occasionally, specialty grocers or online vendors might carry other types, such as:
- Red Walnuts: A rare and naturally red-skinned variety of English walnut known for its buttery flavor and lack of bitterness.
- Butternuts: A North American variety (Juglans cinerea), but these are not commonly sold for commercial food production.

How to Choose Walnuts at the Store
Whether you’re buying English or Black walnuts, in-shell or shelled, there are several key indicators of freshness and quality.
- Check the Appearance: Look for walnuts with clean, intact shells free of cracks, holes, or mold. Shelled walnuts should be pale, plump, and creamy-colored.
- Smell for Freshness: Fresh walnuts have a rich, nutty scent. If they smell sour, musty, or like paint thinner, they have gone rancid and should be avoided.
- Perform the Weight Test: A good quality in-shell walnut will feel heavy for its size, indicating a full kernel. If it feels light, the kernel is likely small or shriveled.
- Consider the Packaging: Look for airtight, resealable packaging, which helps maintain freshness. Many brands, like Happy Belly, clearly indicate the variety, such as 'Chandler,' and the origin, like 'California'.
The Processing Journey to Your Shopping Cart
The walnuts you find at the grocery store undergo a meticulous process to ensure quality and freshness. First, they are harvested and separated from their tough outer husk by mechanical hullers. The walnuts are then dried to an optimal moisture level to prevent spoilage. Next, they are sorted and graded by size and quality. Walnuts destined for the 'shelled' market are then cracked by machines that minimize damage to the delicate kernels. Finally, they are inspected, packed, and delivered to stores.
Conclusion
In summary, the vast majority of walnuts found in grocery stores are the English variety, celebrated for its mild, buttery flavor and versatile use in cooking and baking. While Black walnuts, with their stronger, earthier taste, are less common and typically found in specialty sections, they can be sought out for specific, robust recipes. When purchasing, always prioritize freshness by inspecting the appearance, scent, and weight. By understanding the differences, you can confidently choose the right walnut for your culinary needs.
