Vietnamese cashew nuts are graded based on several criteria, including size, color, quality, and the presence of defects. The grading system helps categorize cashews for different markets and uses. Here’s an overview of how Vietnamese cashew nuts are typically graded:
1. Size
Whole Cashews: Cashews are primarily graded by size, which is indicated by the number of kernels per pound. Common sizes include:
W180 (Jumbo): 180 nuts per pound
W210 (Large): 210 nuts per pound
W240 (Standard Large): 240 nuts per pound
W320 (Medium): 320 nuts per pound
W450 (Small): 450 nuts per pound
2. Color and Quality
White (W): Whole white kernels are the most popular and are graded by their color uniformity and appearance.
Scorched (S): Cashews that are slightly over-roasted during processing but still acceptable in quality.
Dessert (SSP): Broken pieces of cashews, used primarily for cooking and as ingredients.
3. Defects
Whole vs. Broken: The percentage of whole kernels versus broken pieces affects grading.
Speckled or Blemished: Cashews with spots or blemishes might be graded lower.
Scorched and Lightly Blemished: These may be classified separately due to their less-than-perfect appearance.
4. Other Grades
Splits (S): Kernels split naturally or during processing.
Butts (B): Cashew halves with the large end intact.
Pieces (P): Broken pieces of various sizes, often used in processed foods.
5. Packaging and Labeling
Cashews are also graded based on packaging standards, moisture content, and overall presentation, which affect their shelf life and suitability for export.
International Standards
Vietnam adheres to international standards, such as those set by the Cashew Export Promotion Council of India (CEPCI) and other global trade organizations, ensuring that the grading system is consistent with global expectations.
Conclusion
Vietnam is one of the largest producers of cashew nuts globally, and the grading system is essential for meeting the diverse needs of international markets. The grading not only helps in pricing but also in ensuring that buyers receive the quality they expect for their specific applications.
W – 180, is the ‘ King of Cashew ‘ – They are larger in size and very expensive.
W – 210, are popularly known as ‘ Jumbo ‘ nuts.
W – 240, it is an attractive grade which is reasonably priced.
W – 320, are the most popular among cashew kernels and highest in terms of availability, worldwide.

In the cashew nut classification system, the high-quality nuts are usually big, whole-grain, and white nuts. Varieties Of Cashew Tree Grown in Vietnam only produce small and medium raw cashew nut (RCN) sizes. W240 cashew is the best cashew nut of Vietnamese origin, the kernels have Medium Size , beautiful, pale ivory, whole-grain cashew that has between 220 and 240 nuts/pound (395 – 465 beans/kg) and is known internationally as Vietnamese Premium Large Cashew Nuts. W240 cashews are the best cashew nut of Vietnamese origin. https://www.linkedin.com/pulse/which-best-quality-vietnamese-origin-cashew-nuts-hanh-tran/
The taste of cashew nuts is influenced by a variety of factors that contribute to their flavor profile and overall quality. Here are the main determinants:
1. Genetic Variety
Cultivar: Different cultivars of cashew trees can produce nuts with distinct flavors. The genetic makeup of the tree affects the nut’s taste, texture, and size.
2. Growing Conditions
Climate and Soil: The climate and soil in which cashews are grown can significantly impact their taste. Cashews grown in nutrient-rich soils and under optimal climate conditions tend to have a better flavor.
Rainfall and Sunlight: Adequate rainfall and sunlight are crucial for the development of flavorful nuts.
3. Harvesting and Processing
Ripeness at Harvest: Cashews harvested at the right time, when they are fully ripe, tend to have a richer flavor.
Processing Techniques: The methods used to process cashews, such as drying, roasting, and salting, can enhance or diminish their natural flavor.
Roasting: Roasting can bring out the nutty flavors and enhance the aroma of cashews. The degree of roasting can affect the taste, with light roasting preserving more natural flavors and heavy roasting adding a deeper, toasted note.
Salting: Salted cashews can have a more robust flavor due to the contrast between salt and natural sweetness.
4. Freshness
Storage: Cashews that are stored properly retain their flavor better than those exposed to air, moisture, or heat, which can cause them to go rancid.
Shelf Life: Fresh cashews taste better as they maintain their natural oils and nutrients, which contribute to flavor.
5. Oil Content
Cashews with a higher oil content often have a creamier texture and richer flavor. The natural oils contribute to the nut’s characteristic taste.
6. Moisture Content
The right moisture level is important for maintaining flavor. Too much moisture can lead to spoilage, while too little can make the nuts dry and less flavorful.
7. Presence of Defects
Quality Grading: Higher-grade cashews with fewer defects, such as discoloration or blemishes, tend to have a better taste. Defective nuts might have off-flavors or reduced quality.
8. Cultural Practices
Farming Techniques: Organic or sustainable farming practices can impact the taste by ensuring the nuts are grown in healthier environments without harmful chemicals.
Conclusion
The taste of cashew nuts is a result of a complex interplay of genetic, environmental, and processing factors. By optimizing these factors, producers can ensure that cashews maintain their desirable flavor and quality. When selecting cashews, considering freshness, processing, and quality grades can help in choosing the best-tasting nuts.
The quality of cashew nuts also depends quite a lot on the processing process. To get the finished cashew nut, cashew nuts will have to go through many different stages of processing and screening. Each facility has a different processing process, so the quality of each facility’s cashews will also be different. https://vihaba.global/product/cashew-nuts-sk2-vietnamese-cashew-nuts/
The cashew fruit, also known as the cashew apple, is a unique part of the cashew tree that is often overlooked compared to the cashew nut. Here’s what typically happens to the cashew fruit:
Structure of the Cashew Fruit
Cashew Apple:
The cashew apple is the swollen, fleshy part of the cashew fruit. It is pear-shaped and can be red, yellow, or orange in color. It is rich in vitamin C and other nutrients.
Cashew Nut:
The actual cashew nut is encased in a hard shell that grows at the bottom of the cashew apple. The nut is the seed of the fruit.
Uses of the Cashew Apple
Consumption:
In countries where cashews are grown, such as Brazil, India, and parts of Africa, the cashew apple is often consumed locally. It can be eaten fresh or used to make juices, jams, and chutneys.
The cashew apple has a sweet and tangy flavor, but it can be somewhat astringent due to its tannin content.
Juice Production:
Cashew apple juice is popular in regions where the fruit is grown. It can be consumed as a fresh juice or fermented to produce alcoholic beverages such as cashew wine or spirits like feni, which is popular in Goa, India.
Animal Feed:
In some cases, cashew apples that are not used for human consumption may be used as animal feed due to their nutritional content.
Composting:
Cashew apples are sometimes composted, returning nutrients to the soil to support the growth of more cashew trees.
Challenges with Cashew Apples
Perishability:
Cashew apples are highly perishable and have a short shelf life, making them difficult to transport and market outside the regions where they are grown.
Tannin Content:
The high tannin content in cashew apples can make them astringent, which may be off-putting to some consumers. This limits their popularity compared to other fruits.
Limited Market:
The market for cashew apples is not as developed as for the nuts, which means they are often underutilized.
Conclusion
While the cashew nut is the primary focus of commercial production, the cashew apple is a valuable byproduct that is used locally for food and beverages in regions where cashews are grown. The potential for expanding the use of cashew apples exists, particularly through processing into value-added products. However, challenges such as perishability and market demand need to be addressed to maximize their utilization.

Kathryn Paige Hardenの著書で、原書のタイトルは、The Genetic Lottery: Why DNA Matters for Social Equlityというものです。本の帯には、「親ガチャ」を乗り越えろ! とか、個人でなんとか変えられるとエールを送るような文言がならんでいますが、内容はちょっと違うように思います。別に個人が頑張れば遺伝の影響を超えられるといった話は出てきません。本書の主張は、社会の平等は遺伝的な差異に配慮すべきというものだと思います。
