The Scoville Scale and Hatch Chile Heat

Heat is measured using the Scoville scale. This ranks peppers in Scoville Heat Units (SHU). The number reflects the amount of capsaicin, which delivers the burn.

Here’s how it looks in everyday peppers:

• Poblano or Anaheim peppers: About 1,000 SHU. Very mild.
• Jalapeños: 2,500–8,000 SHU. The standard “medium” pepper.
• Cayenne peppers: 30,000–50,000 SHU. Much hotter than Hatch.

Hatch usually lands between 1,000 and 8,000 SHU. That means they can be as gentle as a poblano or as bold as a jalapeño.

So, what is Hatch green chile? The answer is simple yet unique. It’s a pepper grown only in Hatch. Known for smoky, earthy notes, Hatch peppers bring flavor first and heat second. Unlike hot peppers that only scorch, Hatch peppers strike a balance.

Mild, Medium, Hot, and Extra Hot Varieties

When you buy hatch chile peppers, you’ll notice they’re often labeled mild, medium, hot, or extra hot. That’s because farmers grow different seed varieties for different spice levels.

• Mild (about 1,000 SHU): Gentle warmth is the heat level. It is great for soups, stews, casseroles, and green chile mac and cheese.
• Medium (2,500–4,500 SHU): Noticeable spice. But it’s smooth and balanced. Works well in tacos, enchiladas, and chile rellenos.
• Hot (5,000–8,000 SHU): Bold and robust, similar to a jalapeño. Perfect for salsa, chili, and grilled dishes.
• Extra Hot (8,000+ SHU): Manageable but fiery. Adds a kick to sauces and adventurous recipes.

What Makes Some Hatch Peppers Hotter?

Not all Hatch chiles are created equal. Even within the same variety, heat can change. That’s because several factors play a role.

• Seed variety: Seeds are bred for mildness.
• Growing conditions: Sunlight, soil, and temperature in Hatch Valley influence heat. A hot summer often means spicier peppers.
• Harvest timing: Younger peppers are usually milder. Ripened red hatch chiles pack more kick.
• Roasting hatch peppers: Roasting brings out smoky sweetness. It doesn’t erase heat but balances it with a buttery, rich flavor.

This natural variation is part of the excitement. You never get a flat, one-note chile. Instead, you get a complex flavor with just the right amount of zing.

Flavor First, Heat Second

Unlike peppers that exist only to burn your tongue, Hatch chile peppers bring flavor above all else. They’re smoky, earthy, and slightly sweet. The heat comes later, as a complement, not the star. When you roast them, the skin blisters and the aroma fills the air. The taste turns richer and smoother.

Here’s how different heat levels shine in cooking:

• Mild Hatch chiles: Add depth to soups without overpowering.
• Medium Hatch chiles: Brighten tacos, scrambled eggs, or enchiladas.
• Hot Hatch chiles: Turn salsa, chili, or burgers into bold dishes.
• Extra Hot Hatch chiles: Deliver spice-lovers the fire they crave, while still keeping that Hatch flavor.

It’s why chefs and home cooks stock up when the Hatch chile season arrives. They know they’re getting peppers with character, not just heat.

Cooking With Hatch Chiles

So, how can you enjoy Hatch chiles at home? It depends on the hatch green chile heat level you prefer.

• Hot: Great for hearty chili, spicy flavor burgers, or blended into salsa.
