What’s the Scoville Scale?

The Scoville scale is like the spice lover's thermometer. Created by pharmacist Wilbur Scoville back in 1912, it measures how spicy (or “hot”) a chili pepper is by determining the concentration of capsaicin, the compound responsible for that burning sensation in your mouth.

Ratings are expressed in Scoville Heat Units (SHU). For example:

• Plain bell pepper = 0 SHU
• Jalapeño = 2,500–8,000 SHU
• Tabasco pepper = 30,000–50,000 SHU
• Ghost pepper = over 1 million SHU

The higher the number, the more intense the heat. And now, let’s see where our star ingredient, the arbol chili pepper, lands on this fiery map.

A Quick Overview of Arbol Chili Peppers

Arbol chilies — also known as pimiento arbol in Spanish — are small, slender red peppers commonly used in Mexican cuisine. They’re named after their thin, woody stems (“árbol” means tree in Spanish), and they pack quite the punch despite their size.

Typically found dried, these chilies offer both heat and a clean, slightly nutty flavor without too much bitterness. Perfect for salsas, soups, sauces, or even grinding into powder, arbol chilies are a must-have in any well-stocked pantry.

How Hot Is the Arbol Chili Pepper? Scoville Rating Explained

The moment of truth — where does the arbol chili stand on the Scoville scale?

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

Let’s take a closer look at how the arbol chili stacks up against its fiery relatives:

• 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

Here’s where the real magic happens — putting arbol chilies to work in your kitchen!

Top 5 Ways to Use Arbol Chilies:

1. 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.
2. 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.
3. 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.
4. 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.
5. 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

Whether you're shopping at your local grocery store or exploring international markets, here’s what to look for when buying arbol chili peppers:

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.

• Toasting Tip: Always toast arbol chilies before using them in recipes. This enhances their flavor and reduces bitterness.
• Reduce Heat: Remove seeds and inner membranes to dial down the heat a notch.
• Rehydrating: Soak in hot water for 15–20 minutes before blending into sauces or pastes.

Frequently Asked Questions About 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.

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.

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.

Are arbol chilies the same as guajillo?
Nope! Guajillo peppers are milder and sweeter, while arbol is hotter with a grassier, cleaner taste.

Where can I buy arbol chili peppers?
You’ll find them in most supermarkets, Latin American markets, or online retailers like Amazon, Walmart, or specialty spice stores.
