I have had Colombian "ron añejo", specifically a brand called La Hechicera, and it was amazingly good, as a sipping experience easily comparable to the best single malt scotch I've ever had. Sure as hell nothing like cough syrup! Of course, it's like 55 USD a bottle but hey, the good stuff is never cheap.
Personally, I'm content with a beer and a little tequila, but I have the tastes of a peasant...
$100.000 on Mercado Libre. Gulp.
Aged rum is arguably my favorite spirit because it really doesn't require anything else to enjoy. My top shelf was El Dorado 15 year from Guayana but that was many moons ago when I had more to spend on drinks than children's clothes.
