Here's the deal, spiciness is measured by a unit of measurement called the Scoville scale. To put it into perspective, a serrano chili hits about a 10,000 on the scale. Habanero peppers can measure anywhere from 350,000 to 580,000...the Vertigo Cube has a rating of 2,000,000 on the Scoville scale.
Two. F*cking. Million. Literally the same rating as mace. So, yes, it's a tad spicy.
