Late heat in a sauce

[James Harvey]

How do you get late heat in a sauce, specifically a tomato based BBQ sauce? I have black, green and red peppercorns (I know red is a berry) and ground white powder. I also have an assortment of chiles and such. Can someone indicate what will give me that late burn in a sweet tomato sauce?

I find that chipotle peppers packed in adobo sauce gives you that late heat finish.
