One of my favorite YouTube channels now is Hot Ones. This year, they came out with what they call the hottest sauce out, made from a pepper that has yet to be officially classified on the scoville scale. It's apparently twice as hot as a Carolina Reaper.
I highly recommend checking out the Hot Ones series on YouTube if you haven't seen it yet. He has some great interviews with various guests.
Here's a video of the sauce itself though...
