How Spicy Is Pepperoncini Peppers?
Pepperoncini peppers are considered to be a mildly spicy variety of pepper. They typically have a Scoville heat unit (SHU) rating of 100-500, which is relatively low compared to more intensely spicy peppers like habaneros or ghost peppers. The level of spiciness can vary depending on the individual pepper and also the processing method (e.g. pickled vs fresh), but in general, most people find pepperoncini peppers to have a pleasant, mild heat that adds flavor rather than overwhelming spice.
