Guntur vs Byadgi Chilli: SHU and ASTA Colour Data
The heat-versus-colour split in Indian chilli: Guntur Sannam for pungency, Byadgi for deep ASTA colour, with verified figures.
Heat and colour by variety (verified)
Buyers choose Indian chilli on two axes: SHU (Scoville, pungency) and ASTA colour value (extractable colour). Guntur is bought for heat; Byadgi is bought for colour.
| Variety | SHU | ASTA colour | Bought for |
|---|---|---|---|
| Guntur Sannam S4 | 35,000-45,000 | 100-120 | Heat |
| Byadgi | 8,000-15,000 | 130-150 | Colour |
| Teja S17 | see gaps | 110-130 | Heat (high) + colour |
How to read the two axes
- SHU measures pungency. Guntur Sannam S4 at 35,000-45,000 SHU is the workhorse heat chilli and sets the world red-chilli reference at Guntur.
- ASTA colour measures extractable red colour. Byadgi at ASTA 130-150 is bought for colour, not heat, and feeds oleoresin and paprika-style uses.
- Teja S17 carries ASTA 110-130 and is prized for high heat, but a specific SHU figure is widely quoted and not verified, so we withhold it.
