What is Dragon's Breath Pepper? The World's Hottest Pepper Explained

If you have come across Dragon's Breath pepper and wondered what it actually is, you are not alone. This is one of the most talked-about super hot peppers in the world, and it happens to be Welsh.

What is Dragon's Breath Pepper?

Dragon's Breath is an extremely hot chilli pepper developed in Wales by grower Mike Smith. Named after the Welsh dragon, it was originally cultivated for use in topical anaesthetic research. The capsaicin concentration is so high it was explored as an alternative to traditional numbing agents.

When it was unveiled at the RHS Chelsea Flower Show in 2017, it was reported to have reached 2.48 million Scoville Heat Units (SHU), making it one of the hottest peppers ever recorded and rivalling the Carolina Reaper.

How Hot is Dragon's Breath Pepper?

To put the heat in context:

• A standard jalapeno sits at around 5,000 SHU
• A ghost pepper reaches around 1 million SHU
• A Carolina Reaper peaks at around 2.2 million SHU
• Dragon's Breath pepper reportedly hits 2.48 million SHU

That is roughly 500 times hotter than a jalapeno. It is not a pepper you eat raw.

What Does Dragon's Breath Pepper Taste Like?

Despite the extreme heat, Dragon's Breath has a genuinely interesting flavour profile. It is fruity and slightly sweet before the heat arrives. This is what makes it so useful for cooking rather than just heat challenges. Used properly, ground into a rub and blended with complementary spices, Dragon's Breath delivers a heat that builds gradually with real flavour underneath rather than chemical burn.
