The hotness of a chilli is measured using the Scoville scale.

The Bhut jolakia is currently the world’s hottest chilli at 1 041 000 SHU (Scoville heat units).

0.001g/l of capsaicin is the equivalent of 15 SHU.

The Infinity chilli is a new chilli bred in the UK. It’s capsaicin concentration has been measured at 0.256M.

What is its SHU?Do we have a new world record?
