It depends on the peppers. Around here, "normal" bell peppers are not hot at all, and others are generally refered to as chili peppers. I'm not sure what you mean by "red peppers".
It also depends on what your personal "too hot" is.
(I have experience infusing tequila with jalapeños, and that goes off the rails fast)
What exactly happened? Because that was my first thought: just make normal mead and add maybe one chili pepper per bottle.
