Piparras (Ibarra peppers, Capsicum annuum var.) are small, mild, slightly acidic green peppers cultivated in the Basque Country. They are the base of the gilda pintxo, along with anchovies and olives. They are not spicy (Scoville 0-500), are preserved in vinegar, and are an essential ingredient in Basque cuisine and Spanish appetizers.

What are piparras: Ibarra peppers
The piparra is the Ibarra pepper (Capsicum annuum var. annuum), a thin, elongated (5-8 cm) light green pepper with a crispy texture. It is harvested unripe — before it matures and turns red — and preserved in white wine vinegar.
The name "piparra" comes from Basque — pipar (pepper) with the diminutive suffix. It is synonymous with "Ibarra pepper" or "Basque pepper," although a similar variant is also cultivated in the French Basque Country (Iparralde).
What defines piparras compared to other chili peppers is their lack of spiciness. On the Scoville scale, piparras score between 0 and 500 SHU (Scoville Heat Units), compared to 30,000-50,000 for a cayenne pepper or 100,000-350,000 for a habanero. Piparras are not spicy — they have a mild, slightly acidic flavor from the vinegar, with a herbaceous and fresh note.
Ibarra, the Gipuzkoan town that gives the variety its name, hosts the Pepper Fair every September, where the best local productions are exhibited. Ibarra peppers do not have a designation of origin, but local farmers' associations maintain the variety and cultivation standards.
Piparras vs. chili peppers vs. cayenne
Confusion between these peppers is common. Let's clarify it:
| Characteristic | Piparra / Ibarra Pepper | Green chili pepper (generic) | Cayenne | Padrón pepper |
|---|---|---|---|---|
| Species | C. annuum | C. annuum | C. annuum var. cayenne | C. annuum |
| Spiciness (SHU) | 0-500 | 500-5,000 | 30,000-50,000 | 0-500 (some 5,000) |
| Size | 5-8 cm, thin | 5-12 cm, variable | 8-15 cm, thin | 3-5 cm, rounded |
| Color | Light green | Dark green | Red (dried) | Green |
| Preservation | Vinegar | Vinegar or fresh | Dried or powdered | Fresh (fried) |
| Main use | Gildas, appetizers | Condiment | Spicy in cooking | Fried as a tapa |
| Origin | Basque Country | Variable | South America | Galicia |
| Price | 8-15 €/kg (preserved) | 3-6 €/kg | 15-25 €/kg (dried) | 4-8 €/kg (fresh) |
The key difference: piparras are mild and eaten in vinegar as an appetizer. Generic chili peppers can be spicy and are used as a condiment. Cayenne is pure spice. Padrón peppers are fried. Each has its place.
Cultivation in the Basque Country
Ibarra peppers are mainly cultivated in the valleys of Gipuzkoa and Biscay, where the Atlantic climate (mild, humid, without severe frosts) offers ideal conditions. The plant grows up to 60-80 cm tall and produces fruit continuously from July to October.
Harvesting is done by hand when the fruits measure 5-8 cm and are still green. If left to ripen, they turn red and develop a slight spiciness — then they are no longer piparras, but ordinary chili peppers. The harvesting time is crucial to maintain that characteristic mildness.
After harvesting, piparras are pickled in white wine vinegar with salt. The process is simple: 6-7% acidity vinegar, salt (20-30 g/liter), and a minimum of 15 days of maceration. Quality piparras are packaged in glass jars with their covering vinegar. They do not need preservatives — vinegar and salt are sufficient.
Local production is limited. Many of the "piparras" sold in supermarkets are mild green chili peppers from other origins (Navarra, La Rioja, even Morocco or Turkey) pickled in the Basque style. They are not the same — the variety, soil, and climate influence the final flavor.
Uses in cooking: gildas, pintxos and more
The gilda. The queen of Basque pintxos. A skewer with an olive, a Cantabrian anchovy, and a piparra. That simple, that perfect. The name comes from the movie Gilda (1946) with Rita Hayworth — because the pintxo was "green, salty and a little spicy," like the protagonist. The gilda was invented at Bar Casa Vallés in San Sebastián in the 1940s.
The perfect gilda has balance: the saltiness of the anchovy, the fat of the olive, and the crisp acidity of the piparra. Without piparra, it's not a gilda — it's just any other banderilla.

Other uses for piparras:
- Accompaniment for preserves. Open a can of anchovies, place some piparras next to them, a little bread and EVOO. Perfect appetizer in 2 minutes.
- Salads. Chopped piparras add acidity and crisp texture to tomato, potato, or mixed salads.
- On toasts. Crystal bread toast with cream cheese, smoked salmon, and a piparra on top. A combination of textures and flavors that works.
- In sandwiches. Basques put them inside sandwiches like one puts a pickle — it's both a condiment and a garnish.
- Stuffed. Piparras stuffed with tuna, cod brandade, or goat cheese. They are served as pintxos in premium bars in Donostia.
- In stews. Added at the end of a cod, bean, or hake in green sauce stew, they provide acidity that balances the fats.
Fried piparras and sweet piparras
Beyond the classic pickling in vinegar, there are two piparra preparations that are increasingly sought after: fried piparras and sweet piparras.
Fried piparras. These are prepared with fresh Ibarra peppers (green, unpickled), just like Padrón peppers. They are fried whole in hot olive oil over medium-high heat for 2-3 minutes, until the skin wrinkles and browns. They are removed, drained, and served with a pinch of coarse salt. They are mild, slightly sweet from cooking, and not spicy at all — a quick and attractive tapa. They only work with fresh, seasonal piparras (July-October); pickled piparras are not fried.
Sweet piparras. These are Ibarra peppers pickled with a touch of sugar in the brine, which reduces the acidity of the vinegar and provides a very pleasant bittersweet taste. They are the easiest version to eat for those who find traditional piparras too acidic. More and more brands and supermarkets offer this "sweet" variant, ideal for appetizers with cheese or as a side dish for white meats. If you like them mild, they are your best option.
Mercadona and supermarket piparras: are they worth it?
"Mercadona piparras" is one of the most frequent searches, and the short answer is: they are suitable for a quick appetizer, but they are rarely authentic Ibarra peppers. Most large-supermarket piparras (Mercadona, Carrefour, El Corte Inglés) are mild green chili peppers pickled in the Basque style, from Navarre, La Rioja, or imported. They fulfill their purpose, but they lose the herbaceous nuance and firm texture of seasonal piparras.
The difference is especially noticeable in the gilda: a soft or overly vinegary piparra unbalances the pintxo. If you are looking for the complete experience, it is worth upgrading to artisanal piparras from the Basque Country. It's the same principle as with Mercadona's preserves versus gourmet ones: the price per kilo goes up, but the product is in a different league.

Comparative table of pickled peppers
| Product | Spiciness | Acidity | Texture | Main use | Approx. price |
|---|---|---|---|---|---|
| Piparra (Ibarra) | None | Medium | Crisp, firm | Gildas, appetizers | 8-15 €/kg |
| Pickled gherkin | None | High | Very crisp | Hamburgers, salads | 3-5 €/kg |
| Banderilla | Variable | Medium | Variable | Appetizer | 5-10 €/kg |
| Pickled jalapeño | Medium (2,500-8,000 SHU) | Medium | Fleshy | Nachos, Tex-Mex | 4-8 €/kg |

Nutritional value
Piparras are nutritionally light — basically water, fiber, and vitamins, with the salt and acetic acid from the vinegar:
| Nutrient | Per 100 g of pickled piparras |
|---|---|
| Calories | 18-25 kcal |
| Proteins | 0.8-1.2 g |
| Fats | 0.2-0.5 g |
| Carbohydrates | 2-4 g |
| Fiber | 1.5-2.5 g |
| Sodium | 800-1,200 mg (due to vinegar with salt) |
| Vitamin C | 40-60 mg (partially degraded by vinegar) |
| Vitamin A | 150-250 mcg |
The only point to watch is sodium — like all pickles, piparras contain salt. A serving of appetizer (4-6 piparras, about 20-30 g) provides 160-360 mg of sodium, which is reasonable.
Where to buy quality piparras
In the Basque Country: directly from local producers in markets in Tolosa, San Sebastián, Bilbao. The best are seasonal (July-October) freshly pickled ones.
Reference brands: Guindillas Ibarra, Piparras Arantzazu, Guindillas Fina (Gipuzkoa). Look for glass jars that state "guindilla de Ibarra" and Basque Country origin.
Supermarkets: they are available in any Spanish supermarket, but many are generic chili peppers. Read the label: if it says "guindillas en vinagre" without further detail, they are probably not from Ibarra. If it says "piparras" or "guindilla de Ibarra," there is a higher probability of authenticity (although it is not a legal guarantee).
Online: gourmet and specialized stores ship piparras throughout Spain. Buy in glass jars (better preservation than cans) and verify that the covering vinegar is transparent and clean.

Frequently asked questions
Are piparras spicy?
No, or practically not at all (0-500 SHU). That is precisely their appeal: they provide freshness, acidity, and a crisp texture without the heat of spicy chili peppers. A stray piparra might have a slight hint of spiciness, but that is the exception.
How do you make a perfect gilda?
A long skewer. First thread an olive (Manzanilla or Gordal type), then a Cantabrian anchovy folded in half, and finally a whole piparra. The order matters: the olive goes at the bottom (base), the anchovy in the middle (flavor), the piparra at the top (freshness). Some versions add a spicy chili pepper, but the classic gilda is not spicy.
Do piparras expire?
In a sealed jar, they last 2-3 years without problem (best before date). Once opened, in the refrigerator covered with their vinegar, 3-4 weeks. If the vinegar becomes cloudy or the piparras soften too much, discard them.
Can I make pickled piparras at home?
If you have access to fresh Ibarra peppers, yes. Wash the peppers, place them in a sterilized jar, cover with 6% white wine vinegar + 25 g of salt per liter. Seal tightly and wait at least 15 days. They are best after 1 month.
What is the difference between piparras and gherkins?
Different botanical family (piparra is a pepper, gherkin is a cucumber), different flavor (piparra is more herbaceous and less acidic), and different texture (piparra is firmer and crisper, gherkin is juicier). Both are pickled but are not interchangeable in recipes.
What is the difference between piparra and guindilla?
"Piparra" is the Basque name for Ibarra pepper: a specific, green, mild, non-spicy chili pepper (0-500 SHU), harvested unripe and pickled in vinegar. "Guindilla" is a generic term that includes varieties that are spicy. All piparras are guindillas, but not all guindillas are piparras. If it's spicy, it's not a piparra.
How are piparras eaten?
As they are, straight from the jar as an appetizer; in a gilda with anchovy and olive; chopped in salads; on toasts with cheese or smoked fish; inside sandwiches; or fried in oil if fresh. They are eaten whole, including the stem if it's tender.
What are the benefits of eating piparras?
They are very low in calories (18-25 kcal/100 g), provide fiber, vitamin C, and vitamin A, and contain no fat. Since they are not spicy, they are suitable for sensitive stomachs. The only point to moderate is the sodium from pickling. As an appetizer, they are a light alternative to fried foods and salty snacks.
