Arbol chili peppers range from 15,000 to 30,000 Scoville Heat Units (SHU), making them 2-12 times hotter than jalapeños (2,500-8,000 SHU). This guide explains the exact heat comparison, cooking uses, and storage tips for maximum flavor.
| Pepper | Scoville Heat Units (SHU) |
|---|---|
| Bell Pepper | 0 |
| Jalapeño | 2,500–8,000 |
| Serrano | 10,000–23,000 |
| Arbol Chili | 15,000–30,000 |
| Cayenne | 30,000–50,000 |
| Habanero | 100,000–350,000 |
As shown above, the arbol chili pepper scoville rating ranges from about 15,000 to 30,000 SHU. That puts it firmly in the "medium-hot" category — hotter than a serrano, but far less intense than a habanero.
In practical terms, expect a noticeable burn, especially if you eat them whole or use them in large quantities. But unlike some other chilies, arbol peppers don't linger too long on your palate — the heat hits quickly and fades just as fast.
Comparing Arbol Chilies to Other Popular Peppers
- Jalapeño: Mild and versatile, jalapeños are great for beginners. Arbol chilies are significantly spicier, sometimes doubling the heat level.
- Serrano: Often used in salsas and tacos, serranos are similar in size to arbols but slightly milder.
- Cayenne: Known for its bright red color and sharp heat, cayenne is often used in powdered form. It's usually hotter than arbol chilies.
- Guajillo: Another popular Mexican chili, guajillo is milder than arbol (around 2,500–5,000 SHU) with a sweeter, berry-like flavor profile.
- Chile de Árbol vs Chile Pasilla: While pasilla peppers have earthy and smoky notes, arbol is sharper and cleaner tasting.
Best Uses for Arbol Chili Peppers in Cooking
Top 5 Ways to Use Arbol Chilies:
- Make Salsa Roja – Toast the dried peppers lightly in a dry pan, then blend with garlic, tomatoes, onion, salt, and a splash of vinegar. Simmer for extra depth.
- Spice Up Soups and Stews – Toss a few whole dried chilies into your next batch of chicken noodle soup or pozole for subtle background heat.
- Infuse Oils or Vinegars – Place a few arbol chilies in a bottle of olive oil or white vinegar for a few weeks. The result? A beautifully spiced cooking liquid perfect for dressings or drizzling.
- Grind into Powder – If you can't find arbol chili powder at your local store, make your own by toasting and grinding dried chilies in a spice grinder.
- Add to Marinades – Mix arbol powder with lime juice, garlic, cumin, and oil for a zesty marinade for grilled meats or tofu.
Buying Guide: How to Choose the Best Arbol Chilies
What to Look For:
- Dried Chilies – Opt for those that are brittle to the touch but still vibrant in color. Avoid soft or discolored ones.
- Smell Test – A fresh, slightly smoky aroma is a good sign. If they smell stale or musty, pass.
- Whole vs. Ground – Whole dried chilies last longer and retain more flavor. Ground arbol chili powder is convenient but loses potency faster.

Frequently Asked Questions About Arbol Chilies
How hot is an arbol chili on the Scoville scale?
Arbol chilies rate between 15,000 and 30,000 Scoville Heat Units (SHU), placing them firmly in the medium-hot category. This makes them significantly hotter than many common peppers but not in the super-hot range like ghost peppers or Carolina reapers.
How does arbol chili heat compare to jalapeño specifically?
An arbol chili is approximately 2-12 times hotter than a jalapeño. While jalapeños range from 2,500-8,000 SHU, arbol chilies reach 15,000-30,000 SHU. This means even the mildest arbol is nearly twice as hot as the mildest jalapeño, and the hottest arbol can be more than twelve times hotter than the mildest jalapeño.
Which is hotter: arbol chili or jalapeño?
Arbol chilies are definitely hotter than jalapeños. The lowest end of the arbol's heat range (15,000 SHU) is still nearly double the highest end of a jalapeño's heat range (8,000 SHU). When substituting one for the other in recipes, you'll need to use less arbol chili to achieve a similar heat level.
What does "15,000-30,000 SHU" actually feel like compared to jalapeño?
If jalapeños provide a gentle warmth that builds slowly, arbol chilies deliver a sharper, more immediate heat that hits quickly and fades relatively fast. The arbol's heat is cleaner and less vegetal than jalapeño, with less of the lingering burn that some peppers produce. It's intense enough to notice immediately but not overwhelming like habaneros.
Why does the Scoville rating for arbol chilies vary so much (15,000-30,000 SHU)?
Several factors cause this variation: growing conditions (soil, climate, water), maturity when harvested, and even the specific plant genetics. Peppers grown in hotter, drier conditions tend to develop more capsaicin (the compound that creates heat), resulting in higher SHU ratings. The measurement method itself can also introduce some variation.
Can I substitute jalapeños for arbol chilies in recipes?
Yes, but with caution. Since arbol chilies are significantly hotter, you'll need to use less if substituting jalapeños for arbol. As a general rule, use 2-3 times more jalapeño to match the heat of arbol. Remember that jalapeños also have a different flavor profile—more vegetal and less clean/nutty than arbol chilies.
Can I substitute arbol chili with another pepper?
Yes! If you can't find arbol chilies, try cayenne, Thai bird chilies, or a mix of jalapeños and chipotles for heat and flavor balance. For closest heat match, use cayenne (though cayenne tends to be slightly hotter at 30,000-50,000 SHU).
Are arbol chilies good for health?
Absolutely! Like all chili peppers, arbol chilies contain capsaicin, which may help boost metabolism, reduce inflammation, and improve heart health. They're also rich in vitamin C, vitamin A, and antioxidants that support overall wellness.
Do arbol chilies get hotter when cooked?
Cooking doesn't increase the Scoville units, but it intensifies the flavor and distributes the heat more evenly throughout the dish. The heat from arbol chilies becomes more immediate when cooked, though it doesn't linger as long as some other peppers. Toasting dried arbol chilies before use enhances their flavor without increasing actual heat.
Are arbol chilies the same as guajillo?
Nope! Guajillo peppers are milder and sweeter, while arbol is hotter with a grassier, cleaner taste. Guajillo peppers range from 2,500-5,000 SHU (similar to jalapeños), making them significantly milder than arbol's 15,000-30,000 SHU range. Guajillos also have a distinct berry-like flavor that arbol lacks.
How should I handle arbol chilies safely?
Always wear gloves when handling dried arbol chilies, as the capsaicin can transfer to your skin and cause irritation. Avoid touching your face, especially eyes, after handling. If you get capsaicin on your skin, wash with soapy water or use a milk-soaked cloth to neutralize the burn.
Where can I buy arbol chili peppers?
You'll find them in most supermarkets (often in the international or spice section), Latin American markets, or online retailers like Amazon, Walmart, or specialty spice stores. Look for them labeled as "chile de árbol," "arbol chilies," or "tree chilies."
