Rum is sugar cane spirit. That's the only rule. The milky funk of a Jamaican pot still, a 25-year aged Demerara, fresh-pressed cane French agricole: all rum. There's no equivalent of bourbon's "51% corn, new charred oak" rulebook here, which is why the aisle is chaos.
Stop sorting by color (white, gold, dark). Sort by base material and regional style.

White rum (silver / blanco)
Unaged, or briefly aged and filtered clear. It covers clean Cuban-style (Havana Club 3, Bacardi Carta Blanca), grassy white agricole (Rhum Clément Canne Bleue), and wild Jamaican white pot still (Wray & Nephew, Rum-Bar).
They aren't interchangeable. A Daiquiri with Bacardi tastes correct. With Wray & Nephew it tastes like banana paint thinner, unless you're ready for it.
What to buy:
Planteray 3 Stars (formerly Plantation 3 Stars): a blend of Jamaican, Bajan, and Trinidadian white. The best general-purpose white rum under $25.
Havana Club 3 Años (where legal): the Cuban-style benchmark.
El Dorado 3: Demerara white, slightly funkier.
Probitas (Foursquare + Hampden): a high-end, no-sugar-added blend built for cocktails.
Gold / amber rum
Lightly aged, sometimes just caramel-colored, sometimes really barrel-aged. It's a marketing wasteland, so read the label.
Honest gold rum is aged 1 to 3 years by a single producer: Mount Gay Eclipse (Bajan, dependable) or Appleton Estate Signature (Jamaican, lightly funky). El Dorado 5 (Demerara) is surprisingly rich for the price. Use it in a Cuba Libre or anywhere a recipe just says "rum."
Dark rum
"Dark" is a color, not a category. It can mean:
Aged molasses rum: Planteray Original Dark, or Goslings Black Seal.
Heavily caramelized rum: Myers's Original Dark, aged up to four years but with much of its color from caramel.
Demerara rum: El Dorado, Lemon Hart. The rich, dried-fruit, slightly smoky bottles that anchor most tiki recipes.
Use it in rum old fashioneds, dark-rum punches, and the Dark 'n' Stormy.
What to buy: Planteray Original Dark is a well-made everyday dark (it's the rebranded Plantation; old labels are still on shelves). Lemon Hart 151 is the old-school tiki overproof Demerara.
Aged rum (añejo / extra añejo)
Rum's whiskey-adjacent end. Aged 5 to 25-plus years, mostly in ex-bourbon casks, sometimes finished in sherry or port casks. Sip these in rum old fashioneds, rum Manhattans, or neat. Don't waste them in shaken drinks.
Mid-shelf: Mount Gay XO, Appleton Estate 12, El Dorado 12.
Sipping: Foursquare's Exceptional Cask Series (Barbados, single blended), Worthy Park 109 (Jamaican), Hampden Estate 8.
Splurge: Foursquare 2007, 2008, and other vintages, El Dorado 21 (sweeter, more dessert-like), Appleton 21.
Agricole (rhum agricole)
Fresh-pressed cane juice instead of molasses. Most bottles you'll see come from Martinique or Guadeloupe. Martinique alone has an AOC, Rhum Agricole Martinique (France's appellation system, the same one that governs wine). Guadeloupe works under a looser geographical indication. Haitian clairin is a related cane-juice spirit: traditional, often unaged, with native-yeast fermentation that gives it heavy funk.
It tastes grassy and vegetal, with olive brine and sometimes a bit of funk. Nothing like molasses rum. People who don't like rum often love agricole.
Its home is the Ti Punch, the Martinique national drink: agricole, lime, cane syrup, and no ice or barely any. It also makes a grassy Daiquiri instead of a clean one, and a Mai Tai split between agricole and aged Jamaican is worth trying.
White agricole: Rhum Clément Canne Bleue, Neisson Blanc, La Favorite Coeur de Canne.
Clairin: Clairin Sajous, Clairin Vaval, the most rustic agricole-style spirits you can buy.
Navy strength and overproof
Navy strength runs from 54.5% (the Royal Navy's old rum strength) to 57% ABV, the figure tied to the gunpowder-proof story in Gin Decoded. Look for Pusser's and Smith & Cross (technically a Jamaican pot still navy-style).
Overproof is anything 60%+: Wray & Nephew (63%), Planteray OFTD (69%), Lemon Hart 151 (75.5%), Hamilton 151. Don't pour these neat unless you know what you're doing.
Use them for Mai Tai floats and tiki splits. Navy strength also makes a louder Dark 'n' Stormy. A ¼ oz of Smith & Cross adds hogo to a Daiquiri without committing fully.
Funk, hogo, esters
"Funk" and "hogo" mean the fruity, banana-like, sometimes slightly rotten-tropical-fruit aroma that comes from long, wild fermentations and pot distillation. The technical term is "high-ester," since esters are the compounds responsible. Jamaican rums are the loudest.
A high-ester Jamaican like Hampden DOK is the rum version of a heavily peated Islay Scotch. Not a beginner pour.
Where each style shines
Daiquiri: clean Cuban-style or Planteray 3 Stars. Funky white if you want to play.
Mai Tai: Trader Vic's original 1944 recipe used 2 oz of 17-year J. Wray Jamaican, long extinct. The most-cited modern reconstruction splits aged Jamaican (Appleton 12, or a Smith & Cross blend) with aged Martinique agricole. Demerara works if that's what you have, but it's not the canonical replacement.
Dark 'n' Stormy: Goslings, by Gosling's trademark on the name and by taste.
Cuba Libre: anything you'd drink with cola. Don't waste good rum.
Piña Colada: gold or aged rum. White rum disappears under coconut.
Jungle Bird: blackstrap or Demerara. Campari's bitterness needs a rich rum to push back.
How to taste rum
Same rules as whiskey, plus one: smell first, sip second, and watch the finish. Cheap rum has a short, sweet finish that vanishes. Good rum's finish lingers and develops: dried fruit, tobacco, and leather on aged bottles, grass and olive on agricole, banana and funk on Jamaican. A small wine glass is fine. Skip the snifter.
