I genuinely like my baijiu with orange juice once in a while. I'm pretty certain (as certain as one can be through the resulting fog) that I've tried it with gapefruit juice as well. Citrus works, plain and simple. I'm making my own rensheng jiu (medicinal wine) at home, I've thrown an orange and a bit of cinamon stick into the mix. Not bad, although my father-in-law doesn't like it. BJ and pink grapefuit would probably make a nice jello-shooter. Rensheng jiu? I have my doubts about that one.
