I'm basically a Captain Morgan guy... when they had the Sherry Cask Aged stuff, I went out and bought a case. All gone now

Their private reserve is about my favorite, but I like spiced rums. There is always a bottle of Appleton on my shelf. Ron Zacapa, I've had, liked it, but the stores here don't carry it. Mount Gay, especially their old cask version, seems to be more available, and I like it just as well.
If you don't like spiced rums, you probably won't care for Zaya. Still, it's a very nice bottle to add to your collection

Kirk and Sweeney, even their 23 year old stuff is still fairly reasonable, (as top shelf liquors go, anyway) and very, very good. I'd recommend this one even if you _don't_ normally like spiced rums. The Royal Jamaican... I kept the bottle mainly because they don't export this one.
Copper Run distillery, not far from my home, makes a couple excellent rums. If you like white rums, you should try their overproof white. Good stuff.
