Quick answer: Iberian ham is legally classified into four categories, each with its own label or seal color:
- black (100% Iberian acorn-fed),
- red (Iberian acorn, 50% or 75%),
- green (Iberian field bait)
- and white (Iberian bait).
The color indicates the breed purity of the pig and its diet , not the brand or the price.
Serrano ham does not use this color system: it is classified by curing time (bodega, reserva, gran reserva).

I've lost count of the times a customer has shown me a label with a doubtful look and asked me: "José Luis, this red cable tie thing, is it good or is it the cheap one?"
There are no stupid questions. What's stupid is buying without knowing how to read what's in front of you.
Not long ago, a customer came in with a ham under his arm to have it sliced. He told me it was a 5 Jotas, bought online during Black Friday.
I put it on the counter and had to tell him bluntly: that wasn't a 5 Jotas.
At first he was surprised. But I placed it next to the ones we have hanging up, and the difference was obvious: the morphology didn't correspond to a 100% Iberian pig, which is the one that gets a black tag. His had a red one. And 5 Jotas with a red tag doesn't exist.
He told me it had cost him just under 300 euros.
He refused to return it, but he fully understood that he'd been ripped off. 300 euros is considerably less than half the price of a genuine 5 Jotas.
We've been in the Mercado de la Paz for over fifty years, and if there's one thing I repeat every day, it's this: the color of the label isn't just decoration. It's legal information. It tells you exactly what you're buying. And if you know how to read it, nobody can pull a fast one on you.
Let's go to trouble.
What is the labeling of Iberian ham and why does it exist?
Before 2014, this was a bit like the Wild West. Every household called their ham whatever they wanted, and "Iberian" was used for almost anything.
The regulations (Royal Decree 4/2014, an update of the previous one from 2007) brought order to the system. Since then, every Iberian ham or shoulder must have a tamper-evident seal on the hoof—the tag—with a specific color according to two criteria:
- Racial purity of the pig: 100%, 75% or 50% Iberian.
- Type of feeding and handling: acorn, field bait or bait.
That seal isn't put on by the producer just because they feel like it. It's certified by an external organization.
That's why, when you see the right color, you know there's quality control behind it, not just a pretty label.
"The color isn't chosen by the seller. It's certified by the inspector."
The 4 colors of Iberian ham: what each one means

Black label: 100% Iberian acorn-fed
It is the highest category. 100% Iberian breed pig, father and mother registered in the Herd Book, raised free in the dehesa and fed exclusively on acorns and natural pastures during the montanera.
It is what many people know as "pata negra" , although that colloquial name is now reserved, by regulation, only for this category.
If you're looking for the most intense flavor, the finest marbling, and the highest guarantee, this is the label for you.
Red label: Iberian acorn-fed (50% or 75%)
Same type of breeding and feeding —acorns and pastures in the dehesa, during the montanera— but the pig comes from a crossbreed, not from a 100% Iberian breed.
It's not "the cheap, low-quality one." It's an excellent product, with less racial purity, and that's noticeable in the nuances, not in a lack of real quality.
Green label: Iberian field-fed
Pigs raised free-range or semi-free-range in the countryside, but fed mainly on feed instead of acorns. They can be 100%, 75%, or 50% Iberian.
A good middle ground for those who want Iberian products with a less intense flavor profile, and a more accessible price.
White label: Iberian pork fat
Farm-raised pig, raised in intensive farming, fed with feed, cereals and legumes. It can also be 100%, 75% or 50% Iberian.
It's the entry point to the Iberian range: good product, milder flavor, more affordable price.
Is there a blue label or an orange label?
I'm going to save you a pointless search here: no.
The regulations recognize four colors—black, red, green, and white —and no others. If you see references to a "blue label" or "orange label" for Iberian ham, it's not an official standard. It could refer to:
- A color of string or presentation of a specific brand, without normative value.
- A confusion with the seal of a Designation of Origin (which matches the color of the category, but adds the PDO logo).
- Simply put, it's a misinformation.
If someone tries to sell you a ham with a "blue label" as if it were a superior category, be suspicious. There's no such thing.
Here at Álvarez Selección, we do use a blue tag , but it's not part of the official system. We put it on ourselves in the factory drying rooms, with a number and the letter "A" for Álvarez, to separate and track which hams we've selected and prevent them from being confused with those of another customer in the same factory. That's all. It doesn't certify any category or replace the four official ones.
Jabugo Ham and Designations of Origin: one more seal
When you see "Jabugo," "Dehesa de Extremadura," "Guijuelo," or "Los Pedroches" on a label, you're not looking at a fifth color. You're looking at a Protected Designation of Origin, which is part of the color system.
The seal remains black, red, green or white depending on the category of the pig, but it also carries the PDO seal, which certifies that the ham meets additional requirements specific to that area: geographical origin, specific controls, tradition of the region.
It's an extra warranty on top of the basic warranty. It doesn't replace it.

Serrano ham labeling: why it's another story
Here's a very common misconception: people search for "serrano ham label" expecting the same color system as Iberian ham. But that's not the case.
Serrano ham comes from white pigs, not Iberian breeds, so it doesn't fall under the Iberian Quality Standard. Its classification is based primarily on curing time.
- Our wines: minimal curing, the youngest in the range.
- Book: longer curing time, more developed flavor.
- Great reserve: the longest cure, the one with the strongest character.
There's no black, red, green, or white here. There are months of curing, and that's the difference between a decent Serrano ham and an excellent one.

How to read a ham label in 30 seconds
Here's the order in which I always look at a label:
- Part type: ham (hind leg) or shoulder (front leg).
- Feeding and management: acorn, field bait or bait.
- Racial percentage: 100%, 75% or 50% Iberian.
- Seal color: that matches the above. If something doesn't add up, ask.
- PDO Seal (if applicable): additional area and process warranty.
If these five points are clear and consistent with each other, you have all the information you need to buy with confidence.
"You don't need to be an expert. You just need to know where to look."
Ham, shoulder ham, Serrano ham and tastings: at Álvarez Selección, no surprises
In our shop, we have Iberian ham in all four categories: Iberian shoulder ham and Serrano ham, all with clear and verifiable labeling—that's right, without exception. If you have any questions while looking at the ham, I'll answer them myself at the counter.
And if you want to try before deciding, we organize tastings and samplings in the Mercado de la Paz store itself, so you can compare categories and choose with your palate, not just the label.
Everything you buy - whole piece, boneless or sliced - is vacuum-packed to ensure it arrives in perfect condition, whether you pick it up from the store, have it delivered to your home in Madrid, or have it shipped anywhere in Europe.
More than once, after the tasting, the customer has opted for a green cable tie because it's less greasy. And I think that's perfectly fine: here everyone takes the one they like, without the obligation to always go for the most expensive one.

Frequently asked questions about ham labeling
Which is the best label for Iberian ham?
The black label, 100% Iberian acorn-fed, is the highest category: complete racial purity and exclusive acorn feeding in the dehesa.
Is the red label of poor quality?
No. It's Iberian acorn-fed pork, with the same acorn diet as the black variety, but from crossbred pigs (50% or 75% Iberian). It's still a high-quality product.
What is the difference between a green label and a white label?
Both are grain-fed, not acorn-fed. The green variety is free-range (the pig is raised in the countryside, fed on feed). The white variety is intensively farmed. The green variety usually has a slightly more natural flavor profile.
Is there a blue label for Iberian ham?
No, it's not an official category. The only colors recognized by the regulations are black, red, green, and white.
Does Serrano ham have a colored label like Iberian ham?
No. Serrano ham is classified by curing (bodega, reserva, gran reserva), not by color or Iberian breed.

P.S. 1: A black label isn't magic. It's just well-done paperwork behind a good product.
P.S. 2: If someone talks to you about "blue label" with an expert face, smile and keep reading the real one.
P.S. 3: If you have any doubts about a piece, that's what I've been behind the counter for for fifty years. Ask.
