I had some of this in Germany a few weeks ago.
It wasn't as hot as I was expecting. I used a very tiny amount on my finger and tasted it. My eyes watered a bit, my cheeks went a bit red, and it was very tasty
Clearly, you're supposed to just mix a few drops in with whatever sauce you're making and then that'll help to reduce it's potency, but even so, tasting it neat was so not as bad as I was expecting.
