I quit sugar a while back (medical reasons). So one of the few 'sweet' things I have is the sweetness from tobacco I smoke. I don't really do alcohol often with a pipe tobacco anymore. As the rums (and other alcoholic beverages I enjoy) I like are all pretty high-sugar, so it's a relatively rare treat.
Like others have said, black coffee, loose leaf tea (various kinds, I enjoy Oolongs, Puer, Dancong, Darjeelings etc.) and high roast Yerba Mate I find go very well with a pipe.
