What is the hottest pepper 2011?

As of my limited knowledge up until April 2022, the hottest pepper in 2011 was the Trinidad Moruga Scorpion. It was certified by Guinness World Records as the hottest chili pepper in the world, with an average Scoville scale rating of 1.2 million SHU (Scoville Heat Units) and a peak rating of over 2 million SHU. However, there may have been newer developments and discoveries of even hotter peppers since then, so it's best to refer to more recent sources for the most up-to-date information on the hottest peppers.
