I know many people pair scotches and beers with their cigars but to be honest, I usually drink cold seltzer water when I smoke. I find that it really refreshes my palate and allows me to enjoy the cigar I am smoking that much more. It is especially good when reviewing a cigar. It is the only thing I will drink when I do a cigar review.
I have begun to drink rum more often when I smoke. Some of my favorite rums are Ron Barcelo Imperial, Babencourt, which is a Haitian Rum, Havana Club 7 (if you can find it), Barcardi and Ron Zacapa. I know that there are many other rums out there to try but these are what I have had so far.
As far as scotches go, I really haven't tried too many scotches - Johnnie Black, Chivas Regal, Makers Mark (which I really liked) - that's about it. Cognacs, I really have to learn more about as I know there is much to learn and try - Courvoisier, Remy Martin, Hennessey, Martell etc. I will update more as I venture into the world of cognacs.
Until next time, happy smoking!
