High Heat Chilli (20,000–50,000 SHU)
Strong, lingering heat — the 20,000–50,000 SHU band powers hot sauces, chilli oil and snack seasoning, built on varieties like Sanying (Tianying), Zidantou and Seven-Star.
What counts as high heat chilli?
High heat is the band where chilli stops being a background note and becomes the point of the product. It spans 20,000–50,000 SHU — hot enough for dedicated hot-sauce and snack applications, but still controllable in a blend when dosed by weight.
| Variety | Heat (SHU) | Region | Best for |
|---|---|---|---|
| Sanying / Tianying | 20,000 – 50,000 | Henan, Hebei | Hot sauce, chilli oil |
| Zidantou (bullet pepper) | 20,000 – 50,000 | Shandong, Anhui | Hot sauce, industrial food |
| Seven-Star | 20,000 – 50,000 | Shandong, Shanxi | Snack seasoning, hot-pot |
| New Generation | 20,000 – 50,000 | Shandong | Seasoning, powder |
What is high heat chilli used for?
- Hot sauces and chilli oil
- Snack and instant-noodle seasoning
- Hot-pot and Sichuan-style bases
- Industrial food and processed seasoning
How to specify high heat chilli
Start from your target SHU window, then name the variety. Sanying and Zidantou are the classic hot-sauce pair; Seven-Star suits snack and hot-pot bases. Confirm form (powder, flakes or segments), moisture and mesh — heat is non-linear, so a precise window is what keeps your sauce consistent batch to batch.
Heat values are representative per variety. Confirm your exact SHU window and form when you inquire.
Blend math: how much high-heat to dose
Heat blends roughly linearly by weight as a first-order rule, so a blend's heat is the weighted average of its ingredients. To hit a 10,000-SHU sauce from a 50,000-SHU Sanying powder, you need 10,000 ÷ 50,000 = 20% chilli and 80% base. From a 20,000-SHU lot you would need 50% chilli instead.
That is a 2.5× difference in dosing for the same finished heat (50% vs 20%) — which is why a precise SHU window is a cost and consistency decision, not a formality. The same batch of "high heat" can sit anywhere from 20,000 to 50,000 SHU, and your recipe changes 2.5× across that span.
How high heat scales against the other bands
| Band | SHU | Midpoint | Relative to high heat |
|---|---|---|---|
| Medium | 10,000 – 20,000 | 15,000 | ~0.4× (high is ~2.3× hotter) |
| High | 20,000 – 50,000 | 35,000 | 1× |
| Extra hot | 50,000 – 70,000+ | 60,000 | ~1.7× (extra hot is ~1.7× hotter) |
Midpoints are arithmetic estimates for comparison only — heat is non-linear, so these ratios guide dosing direction, not exact substitution.
