The black is just "extra hot". It's still nothing crazy. I just got into them seriously about a year and a half ago. I have 4 at work and about 11 at home lol. I try not to get too many at once. But my parents got me a 7 pack of small bottles for Christmas from Big Lots, and I was pleasantly surprised by 3 out of the 4 I've tried so far, considering I'm guessing it was $20 or less.

The black has a distinct smoked flavor.
