Rum vs Tequila

Two sugarcane/agave cousins from the Americas with very different regulatory backbones. Tequila has the CRT and additive disclosure (sort of). Rum is the wild west: most producing countries permit undisclosed sugar, caramel, glycerin, and oak extract.

Verdict

100% agave tequila wins, clearly. Even compared to additive-free Barbados rum, tequila's lower sugar baseline and tighter regulation make it the safer choice. Sweet aged rums lose to tequila by a wide margin.

Which one for which situation

You want the cleanest options of each
→ Tequila
Espolòn (additive-free tequila) beats Mount Gay Eclipse (additive-free rum) on chemistry load.
You're hangover-sensitive
→ Tequila
Most aged rums carry undisclosed sugar. Tequila's sugar baseline is lower.
You want zero added sugar guaranteed
→ Tequila
Barbados rum has GI rules; tequila has its own. Both can be additive-free. But tequila brands are more often certified.
You're drinking tiki cocktails anyway
→ Rum
The chemistry difference is moot when buried in 30g of cocktail sugar.

FAQ

Is tequila healthier than rum? ▾

Yes, in most direct comparisons. Tequila has a lower sugar baseline, stricter additive regulation, and generally less aging-derived congener load. Premium additive-free rums close the gap.

Which has more calories, rum or tequila? ▾

Plain tequila and plain rum at 40% ABV are identical in calories. Spiced rum (under 40% ABV) and added-sugar rums carry meaningful extra calories.

Does rum give worse hangovers than tequila? ▾

Generally yes, most aged rums carry hidden sugar that drives hangover symptoms, while 100% agave tequila does not.
