ELI5:How is Scoville Test performed?
gpt
They take a small, exact amount of the dried pepper in question, dissolve it in alcohol, then mix this solution into a cup of sugar water.  They have 5 tasters drink that concoction to see if any of them can still detect the heat of the original pepper.  If 3/5 tasters can detect the heat, then they'll dilute the solution further until they can't.  

The more dilution needed before the heat can't be detected, the hotter the pepper, and the higher its score on the Scoville scale.
