To this point, I dig rum, but I don't know too much about it, nor have I tried that many varieties. That said, I like it neat, too, so it doesn't really work any better/worse than whiskey with regards to the heat.It's hot so I'm on a rum kick. Made Mojito's the other night for the first time in 4 years.
when it's 90 and 80% humidity at 530PM Bourbon just doesn't hit the spot.
If I'm mixing up a ****tail while it's hot, I prefer a whiskey sour. A nicely crafted one with scotch and egg white if I have the time and energy for it, otherwise just a massive jug of Evan Williams Bottled in Bond plus Country Time Lemonade for the poor man's version.
I have a one-gallon Drink Tank that I fill with poor man's whiskey sour and take golfing. Refreshing way to drink whiskey on a hot day.
Edit: Here's the Drink Tank. These things are badass. This is the one-gallon version.
