I've found coffee is the best and tea (thanks
@hoosierpipeguy) is great as well, but I don't drink decaf coffee and generally don't enjoy a pipe first thing in the morning and decaf tea is more of a late night thing, so that doesn't happen much. Enjoyed a rare Coke (really don't drink and soda type stuff at all anymore) in my wife's vehicle (double the gas mileage, lol, she has since commented on the faint odor of tobacco) on the way home from a little road trip the other day and it was nice with a coupe of bowls, although the ice didn't make it all the way. Something about the carbonation.
Now we FINALLY have spring I'll be out on the deck more and iced tea is a great fit, I'm partial to hard cider with a pipe but that stuff goes down so easy (!), a very citrusy homemade margarita on occasion. I've had whisky while pipe smoking and it's good but I've found it's not my preference as a combination and now I just enjoy a dram as I used to - totally for it's own merit, usually in the evening, but that's only once a week or so. Honestly, most days I enjoy a bowl or part of one at lunchtime and I don't drink anything.
