Wagyu A4 and A5 represent the highest quality grades in the Japanese beef classification system. A5 is the absolute top quality with the most marbling (fat marbling), while A4 also offers premium quality but with slightly less fat distribution. The difference lies mainly in the intensity of the buttery flavor, texture and melting point of the meat.
What exactly do the wagyu quality grades A4 and A5 mean?
The Japanese Wagyu classification system uses a letter-number combination where the letter indicates the yield and the number determines the quality. The A stands for the highest yield (yield grade), while the numbers 1 to 5 indicate quality based on four criteria: marbling, meat color, fat color and meat firmness.
A4 Wagyu has excellent marbling with clearly visible fat veins throughout the meat. The marbling score ranges between 5-7 on the BMS scale (Beef Marbling Standard). The meat has good firmness and a bright, cherry-red color.
A5 Wagyu represents absolute perfection with the highest marbling score of 8-12 on the BMS scale. The meat displays an almost artwork-like fat marbling that is evenly distributed throughout the entire piece. The texture is exceptionally tender and the meat has the ideal color and firmness.
The assessment is carried out by certified graders who individually inspect each carcass. They examine the density and distribution of fat veins, the brightness of the meat color and the overall quality of the meat. This strict selection ensures that only the very best meat receives the A4 and A5 classification.
How can you recognize the difference between A4 and A5 wagyu by taste and texture?
A5 Wagyu literally melts on your tongue at body temperature, while A4 Wagyu has a slightly firmer bite but is still extremely tender. The buttery flavor is more intense and creamier in A5 due to the higher fat content, whereas A4 offers a more balanced ratio between meat and fat.
When tasting A4 Wagyu, you experience a rich, full flavor with a pleasant texture that chews tenderly. The meat has sufficient resistance to remain interesting during eating. The flavor is complex with nutty undertones from the quality of the fat.
A5 Wagyu, on the other hand, offers an almost surreal eating experience. The meat melts away without chewing, immediately releasing the intense buttery flavor. This characteristic makes A5 particularly suitable for small portions, as the richness can be overwhelming.
The mouthfeel also differs significantly. A4 provides a satisfying texture that gives your teeth something to work with, while A5 is more of a sensory experience where flavor takes center stage. Both qualities have their own charm, depending on what you seek in a steak experience.
Why is A5 wagyu more expensive than A4 and what justifies the price difference?
A5 Wagyu costs significantly more because only 3-5% of all Wagyu cattle achieve this top quality. Production requires longer breeding periods, special feeding and more intensive care, while A4 is already rare but occurs slightly more often in the highest quality herds.
The breeding programs for A5 quality are extremely demanding. Cattle receive special feed for years, including high-quality grains and sometimes even beer or sake. They live in stress-free environments with individual attention. This intensive care often lasts 28-32 months, compared to 24-28 months for A4 quality.
The selection process is ruthlessly strict. Of thousands of cattle, only a few achieve the A5 classification. This rarity, combined with international demand from top restaurants and meat lovers, drives up prices.
Production costs are also higher due to the longer breeding period and more intensive care. Farmers invest more time, feed and labor per animal for A5 quality. These costs are passed on in the final price, but the quality experience justifies this for lovers of the very best meat.
Which wagyu quality should you choose for the perfect steak experience?
Choose A4 Wagyu for your first Wagyu experience or if you enjoy balanced texture with rich flavor. A5 is ideal for special occasions, small portions or when you want to experience the ultimate melting sensation. Your budget and personal preference for texture determine the best choice.
For romantic dinners or business occasions, A4 offers an excellent balance between luxury and palatability. You can serve larger portions without guests being overwhelmed by the richness. The texture provides satisfaction and the meat remains interesting throughout the entire meal.
A5 Wagyu fits perfectly with culinary explorations or as the highlight of a tasting menu. Serve smaller portions (75-100 grams) to appreciate the intensity without saturation. This quality requires minimal preparation – light searing is sufficient.
For preparation of both qualities, the rule is: less is more. Use only salt and pepper, and grill briefly at high temperature. A4 tolerates slightly longer cooking, while A5 is best seared very briefly to preserve the texture.

Frequently Asked Questions
How do I store A4 and A5 wagyu at home to maintain quality?
Store wagyu in the refrigerator at 1-3ยฐC and use within 3-5 days of purchase. Wrap the meat in breathable paper (not plastic) and place it in the coldest part of your refrigerator. For longer storage, you can freeze wagyu for up to 6 months, but this may slightly affect the texture.
Can I prepare A4 and A5 wagyu medium-rare or well-done, or must it always be rare?
A4 wagyu can be excellently prepared medium-rare and retains its juiciness. A5 wagyu is best rare to medium-rare, as longer cooking reduces the unique melting effect and can cause the fat to run out. Well-done is discouraged for both qualities due to quality loss.
Why is it recommended to serve smaller portions of A5 wagyu than A4?
A5 wagyu has an extremely high fat content (up to 50%) making it very rich and filling. Portions of 75-100 grams are ideal because larger quantities can be overwhelming. A4 wagyu is less fatty and therefore suitable for standard steak portions of 150-200 grams.
Which side dishes pair best with wagyu A4 and A5?
Choose light, neutral side dishes that don't overshadow the wagyu: grilled vegetables, simple salad, roasted potatoes or steamed rice. Avoid heavy sauces - a little sea salt or wasabi is sufficient. The focus should remain on the meat.
How do I recognize authentic A4/A5 wagyu and avoid counterfeit products?
Genuine Japanese wagyu always has a certificate of origin with the registration number of the cattle. Only buy from reputable butchers or importers who are transparent about the origin. Pay attention to the price - extremely cheap 'wagyu' is usually not an authentic Japanese product.
Is there a difference in cooking time between A4 and A5 wagyu steaks?
A5 wagyu has a shorter cooking time due to the higher fat content that melts faster. Grill A5 only 1-2 minutes per side at high temperature. A4 wagyu can take 2-3 minutes per side, depending on thickness. Both qualities should be brought to room temperature before cooking.
