The peppers
Every Harmony bottle starts with a pepper chosen for its flavor, not just its Scoville rating. Click any cultivar to read origin, Scoville band, and the sauce it headlines.
Heat map
Relative heat for every pepper we grow and blend.
Harmony Hot Sauce bottles include a relative heat indicator on every label. The chart above gives you the heat range in Scoville Heat Units (SHU's) represented by the thermometer on the bottle.
The peppers we use are all much hotter than the end product. Our recipes are developed to find the perfect complementary ingredients for each unique type of pepper in a way that lets both the heat and the flavor come shining through, and in a heat range that will not cause you to spontaneously combust! Of course, there is a wide range of tolerance among those of us who enjoy hot peppers. The Relative Heat Scale gives you a quick way to understand the intensity of each product.
