Hello neighbors! Having recently moved to Spain, I always get confused when I visit the ham section in supermarkets. Prices range from tens to hundreds of euros, and the packaging contains many unfamiliar terms like Bellota and Cebo de Campo… It can be really confusing. After spending some time researching, I finally understood the most important Iberian ham grading system. I’m sharing it here hoping to help fellow newcomers!
In fact, the easiest way to quickly identify the quality of Iberian ham is to look at the small plastic tag hanging from the ham’s back hoof. Since 2014, Spanish regulations require all Iberian hams to wear one of four different color tags based on the pig breed and feeding method. This acts like a “passport” for the ham, making it clear at a glance.
The Four Color “Passports” of Iberian Ham

To make it clearer, I summarized a simple table from the Spanish Ham Labeling resource that explains the meaning behind each color tag:
| Tag Color | Meaning | Pig Breed Purity | Rearing Method |
| Black | Bellota 100% Ibérico | 100% pure Iberian pig | Fully free-range in oak forests during acorn season, feeding on acorns |
| Red | Bellota Ibérico | 50% or 75% Iberian pig | Free-range during acorn season, feeding on acorns like black tag |
| Green | Cebo de Campo Ibérico | 50% or 75% Iberian pig | Raised in open pastures, feeding on cereals and natural plants |
| White | Cebo Ibérico | 50% or 75% Iberian pig | Indoors in farms, fed only with cereals |
In short, the black tag represents the highest grade — the legendary “100% acorn-fed purebred Iberian black pig ham,” the most expensive with the richest flavor. The red tag is also excellent quality with a great cost-performance ratio. The green and white tags are relatively more affordable and suitable for everyday consumption. Additionally, you might have heard the Pata Negra term before, which many believed meant top-quality ham due to the black hoof. However, this is no longer a reliable standard, since many crossbred pigs also have black hooves. So, please always look for the colorful tags!
Note that this color system applies only to Jamón Ibérico. Another common ham, Jamón Serrano, is not included here as it involves different production techniques and pig breeds and is usually cheaper. Hopefully, this little knowledge helps you! Next time you go to the supermarket or a ham shop, you can confidently choose your ham! Which type of ham do you like best? Feel free to leave your comments!
