Sweet vs Hot (Low-Heat) Paprika: What's the Difference
Paprika comes in two grades: sweet, for colour with no burn, and low-heat, for colour plus mild heat and chilli aroma. This comparison explains the SHU split, the varieties behind each, and how to specify the grade you need.

The core difference
| Dimension | Sweet paprika | Low-heat paprika |
|---|---|---|
| Heat (SHU) | Under 500 | Under 10,000 |
| Varieties | Xinjiang sweet pepper, Red Dragon 23 | Yidu red, Wangdu |
| Colour (ASTA) | 80–180 (sweet grade) | 60–240 range, variety-dependent |
| Character | Colour, no burn | Colour + mild heat + chilli aroma |
Why the choice matters
Both grades come from low-heat, high-colour sweet peppers — the paprika powder page details the grades. Sweet paprika (under 500 SHU) is bought for colour and mild flavour with essentially no burn. Low-heat paprika (under 10,000 SHU) adds mild heat and a clear chilli aroma on top of the colour. Neither is interchangeable with chilli powder, which is made from hotter varieties (20,000–70,000+ SHU) to add heat.
When to choose each
Choose sweet paprika for colouring where heat is unwanted — natural red colouring, colour blending, mild snacks. Choose low-heat paprika where the product needs colour plus a mild warmth and chilli aroma on top.
How to specify
Confirm your target ASTA colour value and heat level when you inquire — the supply range is roughly ASTA 60–240 depending on variety and grade. See ASTA colour value for how colour is measured.
Heat and colour values are representative. Confirm your exact SHU window, ASTA, form and mesh when you inquire.
Frequently Asked Questions
What is the difference between sweet paprika and low-heat paprika?
Sweet paprika (under 500 SHU) is made from high-colour sweet pepper varieties like Xinjiang sweet pepper and Red Dragon 23, with an ASTA colour value of 80–180. Low-heat paprika (under 10,000 SHU) comes from varieties like Yidu red and Wangdu, adding mild heat and clear chilli aroma on top of colour.
Can low-heat paprika replace sweet paprika?
Only if the added heat and chilli aroma are acceptable in your product. Sweet paprika is under 500 SHU; low-heat paprika is under 10,000 SHU. Confirm your target colour value and heat level when you inquire.
Which paprika is best for food colouring?
High-colour sweet pepper varieties from Xinjiang — such as Red Dragon 23 and US Red — give the strongest colour per unit, and are the standard for paprika oleoresin extraction and food colouring.
