In the world of canned fish, few confusions are as frequent as that between sardines and sardinillas. Most consumers assume they are the same product in different sizes, and technically they are not wrong, but the real difference goes far beyond size. It affects flavor, texture, price, presentation, and, above all, the most appropriate use for each.
At Mercat del Ninot, we have been selling both for decades, and the most common question at the counter is always the same: "Which one should I get?" The answer depends on what you want them for, and this guide gives you the criteria to make an informed decision.
What is a sardine and what is a sardinilla?
Sardine and sardinilla are the same fish: Sardina pilchardus, the European sardine from the Atlantic and the Mediterranean. The difference is exclusively in age and size at the time of capture:
- Sardinilla: young sardine, caught when measuring between 8 and 12 cm in length. It is between 1 and 2 years old. It is smaller, thinner, with finer bones and more tender flesh.
- Sardine: adult specimen, caught from 14-16 cm. It is 2 or more years old. It is larger, meatier, with thicker bones and higher fat content.
There is no rigid and official boundary between these two denominations. Canning regulations establish indicative ranges, but each producer applies their own selection criteria. What is consistent is that "sardinilla" always implies a significantly smaller specimen than "sardine."
Comparison table: sardine vs. sardinilla
| Characteristic | Sardine | Sardinilla |
|---|---|---|
| Size | 14-20 cm | 8-12 cm |
| Weight per piece | 20-40g | 5-15g |
| Pieces per can (standard) | 2-5 | 8-20 |
| Fat content | High (8-15%) | Medium (5-10%) |
| Bones | Noticeable, edible | Very fine, almost imperceptible |
| Texture | Firm, meaty, juicy | Tender, delicate, smooth |
| Flavor | Intense, marine, deep | Mild, clean, elegant |
| Average price (can) | €2-6 | €4-12 |
| Best use | Cooking, hearty tapas | Appetizer, gourmet platter |
Flavor: the difference that really matters
Size influences flavor because it affects two key variables: fat content and the flesh-to-bone ratio.
Adult sardines have more intramuscular fat, which translates into a more intense, marine flavor with more umami. When you open a can of large sardines in olive oil, the first bite fills your mouth with flavor. It is a product with character that makes no apologies. The bones are noticeable but perfectly edible (and an excellent source of calcium).
Sardinillas, on the other hand, have a cleaner, more elegant, and more subtle flavor. The flesh is more tender, the bones are so fine they are imperceptible, and the overall experience is more refined. It's the difference between a potent aged cheese and a mild semi-cured cheese: both are good, but for different occasions and palates.
If you've never paid attention to this difference, we recommend trying both side-by-side. Open a can of each, place them on a plate, and compare. The difference is immediately noticeable. Our guide to canned sardines delves into the quality criteria for choosing the best ones.

Price: why sardinillas are more expensive
Sardinillas consistently cost more than standard sardines, and there are objective reasons for this:
- Lower yield per piece: each sardinilla weighs 5-15 grams compared to 20-40 grams for an adult sardine. To fill a can of the same drained weight, 3-4 times more pieces are needed.
- Higher handling cost: each piece is handled individually during canning. More pieces per can means more labor time per unit of product.
- More demanding selection: uniform size is a visual requirement for quality sardinillas. Pieces that do not meet the size range are discarded or destined for lower-grade preserves.
- Limited season: the best quality sardinillas are caught at specific times of the year when the young specimens have the optimal size and fat content.
- Gourmet positioning: the market associates sardinillas with a more premium product, which allows for a higher margin in the distribution chain.
This does not mean that standard sardines are a second-rate product. It means that the price of sardinillas reflects a higher real production cost and a different market positioning. Good Dardo sardines in olive oil at €3.25 are an exceptional product for their price.
Common presentations and formats
Canned sardines
Adult sardines are usually presented in these formats:
- In olive oil: the classic and best-selling format. The oil preserves the moisture of the flesh and slightly softens the flavor. Dardo sardines in olive oil (12-18 pieces) are an example of quality standard sardines at an affordable price.
- In tomato: tomato sauce provides sweetness and acidity that complement the intensity of the sardine. Our sardines in tomato in a jar are perfect for those looking for a product ready to spread or add to pasta.
- Smoked: smoking adds a layer of complexity to the flavor that completely transforms the sardine. Smoked sardine fillets are an alternative to smoked salmon with more personality and at a better price.
- In escabeche: vinegar, paprika, and spices create a powerful and traditional flavor profile.
Canned sardinillas
Sardinillas are generally presented in more elaborate formats:
- In extra virgin olive oil: the premium presentation. Uniform pieces, perfectly aligned in the can, covered in first-press oil.
- In spicy sauce or with chili: a touch of spice that complements the smoothness of the sardinilla.
- With lemon: lemon zest and aromatic herbs that highlight the delicacy of the fish.

When to use sardines and when to use sardinillas
Choose sardines when:
- You are going to cook with them (pasta, empanadas, warm salads).
- You are looking for a hearty and satisfying bite as a tapa or snack.
- Budget matters and you want maximum flavor per euro.
- Sardines are accompanied by other strong ingredients (tomato, peppers, garlic).
- You are preparing a dish where the sardine is flaked or mixed in.
Choose sardinillas when:
- You are going to serve them as an appetizer or starter where fish is the star.
- You are setting up a gourmet conservas platter to share.
- You are looking for a delicate product for special occasions.
- Bones are an issue (children, people with difficulty eating bones).
- You want to impress visually: sardinillas in an open can are much more attractive.
Either works for:
- Toasts and canapés (adjusting the amount according to size).
- Cold salads with vegetables and vinaigrette.
- Eating directly from the can with good bread.
The smoked sardine: a third way
If you are interested in sardines but are looking for something different from the classic canned sardine in oil, smoked sardines deserve your attention. The smoking process radically transforms the flavor and texture of the sardine: the flesh acquires smoky notes, becomes firmer, and develops a complexity that places it in a completely different category.
Our smoked sardine fillets and 120g smoked sardine loins are products that surprise those who try them for the first time. For hospitality or large families, the 900g format offers the best quality-price ratio.
How to store canned sardines and sardinillas
Both follow the same storage rules:
- Unopened: in a cool, dry, and dark place. Ideal temperature: 15-20 °C. Quality preserves improve over time during the first 2-3 years (like wine), developing deeper flavors and a silkier texture as the oil penetrates the flesh.
- Once opened: transfer the contents to a glass container with a lid, making sure the fish is covered with oil. In the refrigerator, 3-5 days maximum.
- The oil from the can: don't throw it away. It is oil flavored with the taste of fish and is perfect for dressing salads, spreading on bread, or adding to a sofrito.
Frequently asked questions
Are sardinillas healthier than sardines?
There is no significant nutritional difference. Both are rich in omega-3, protein, calcium, and B vitamins. Adult sardines have slightly more fat and omega-3 per gram. Sardinillas have finer bones that are easier to digest. Both are excellent foods.
Why are sardinillas more expensive than sardines?
For three reasons: more pieces are needed to fill a can (lower yield), each piece is handled individually (more labor), and selection by uniform size discards part of the product. The production cost is higher, and gourmet positioning also plays a role.
Do canned sardines and sardinillas have bones?
Yes, both retain bones. Sardinilla bones are so fine they are practically imperceptible. Adult sardine bones are thicker and noticeable, although they are edible and an excellent source of calcium. If bones bother you, choose sardinillas.
Which sardine is best for children?
Sardinillas. The bones are finer, the texture is more tender, and the flavor is milder. For children starting with canned fish, mild olive oil sardinillas are ideal. Sardines in tomato also work because the sweetness makes them more appealing.
Do canned sardines improve with age?
Yes. Quality sardines in extra virgin olive oil develop deeper flavors and a silkier texture during the first 2-3 years. The oil penetrates the flesh, and the flavors harmonize. This is known as 'aging' preserves.
Can you make a conservas platter with only sardines?
Absolutely. A platter with sardines in olive oil, in escabeche, in tomato, and premium sardinillas offers a wide variety of flavors and textures. Add breadsticks, olives, pickles, and good olive oil for a complete appetizer.
