basically rum goes from shit to amazing, like all alcohols.
SHIT------------------------------------->
Capt. Mt. Gay Ron Z.
coke is shit, always has been, i dont care what people tell you about bubbles, and tradition, taste tests always lie, neither coke or pepsi is better. with this in mind use ginger ale.
gingerale goes with rum like sex goes with wet sheets. It accentuates the subtle flavors of good rum and covers bullshit vanilla flavors of cheap Capt.
but be warned, "good rum goes with good friends" period. of you are closer to the Ron Z. part of the scale, just serve it warm and enjoy it slowly.
here's a review of Ron Z.
