I've been fond of rum for years, but have only begun exploring beyond Mount Gay, Appleton and Myers in the past couple of years.
My preferences lean distinctly toward drier rums: Mount Gay, Flor de Caña, Barbencourt 5 star, Cruzan Single Barrel.
I'm learning the sweeter style rums (Pat's preference) become more approachable for me simply by adding ice, but as a converted whiskey guy, I doubt I'll ever convert. One exception - I keep a bottle of Zaya around as an occasional after-dinner liqueur. Pat likes El Dorado 12, Matusalem and Agnotura 7.
Favorite rum: Havana Club 7 (good motivation for travel

Favorite bargain rum: Flor de Caña 4
Rum I'm still waiting to find: RL Seale
BTW - I love the simple, straightforward terminology Jimbo and Sue have developed and the compact reviews presented. Hopefully, I can contribute as we adventure forward.
