Chiltepin Scoville Scale: How Hot Is the Red Gold of Sonora?
Wild chiltepin reaches 50,000-100,000 SHU on the Scoville scale. How spiciness is measured, what the numbers mean, and where chiltepin sits among the hottest Mexican chiles.
By Julian Orozco, founder of La Yaquiyori

When we say wild chiltepin has 50,000 to 100,000 Scoville heat units (SHU), what does that actually mean? How does it compare to chiles you already know? Here is the clear breakdown.
What is the Scoville scale?
The Scoville scale is the standard measure of chile spiciness. Created in 1912 by American pharmacist Wilbur Scoville, it measures the concentration of capsaicin - the chemical compound that produces the burning sensation. More capsaicin, more Scoville units.
The original test was organoleptic (a panel of tasters diluted chile extract in sugar water until they could no longer detect spiciness). Today it is measured with high-performance liquid chromatography (HPLC), which directly quantifies capsaicinoids.
Chiltepin in context
| Chile | Spiciness (SHU) | Notes |
|---|---|---|
| Bell pepper | 0 | No spiciness |
| Poblano | 1,000-2,000 | Very mild spiciness |
| Jalapeño | 2,500-8,000 | Moderate spiciness |
| Chile de árbol | 15,000-30,000 | Medium-high spiciness |
| Cayenne | 30,000-50,000 | High spiciness |
| Chile piquín | 30,000-60,000 | High, persistent |
| Wild chiltepin | 50,000-100,000 | Explosive and short-lived |
| Tabasco sauce | 2,500-5,000 (bottled) | Industrial dilution |
| Habanero | 100,000-350,000 | Extreme spiciness |
| Carolina Reaper | 1,500,000-2,200,000 | World record |
Why chiltepin feels different
Wild chiltepin has an "explosive and short-lived" spiciness: intense at the start, fading quickly. This is related to its capsaicinoid profile, where capsaicin dominates over dihydrocapsaicin.
That makes it ideal for dishes where you want impact without the spiciness dominating the next bite. It is why it works so well in aguachile, seafood cocktails and michelada: it hits hard, but lets you taste what comes next.
Spiciness in La Yaquiyori sauce
La Yaquiyori sauce keeps the natural range of wild chiltepin (50,000-100,000 SHU) because it is single-varietal - it is not diluted with milder chiles to "standardize" the product. Each batch varies slightly with the year's harvest, but always within the wild chiltepin range.
To feel that spiciness in a single-varietal sauce, try the Pack Duo. Also see our story.
For reference: one tablespoon of the sauce is roughly the spiciness of 3-5 whole dried chiltepin peppers. Start with a small amount and adjust - chiltepin hits more at the end of a sip in drinks and the middle of a bite in solid food.
