Scoville units are also not a very good method of measuring spiciness (not that I have a better one). Ime I’ve eaten a variety of things at a variety of Scoville levels and I’ve found some of the lower ones way, way hotter than some of the higher ones. I’ve had many, many, many high/extra/killmepls strength hot sauces but still believe a homegrown ghost pepper to be the hottest thing I’ve ever eaten.
