It is sweeter and tangier than spicy and is made of different tastes like brown sugar, ginger, soy sauce, garlic, vinegar, chili flakes, and hoisin sauce. The mild spiciness from the red chili flakes is just a half teaspoon and can be reduced or left out completely. Everything else is more sour than spicy. The only thing that has a spicy kick to it is the hoisin sauce, which has some chili peppers in it.
