Factor by factor

Congeners Moderate

Byproducts of fermentation (methanol, acetaldehyde, fusel alcohols). Strongly linked to hangover severity; darker, less-distilled spirits carry more.

Histamines Low

Produced by bacteria during fermentation/aging. Trigger flushing, headaches, congestion in sensitive drinkers. High in red wine, beer, aged spirits.

Polyphenols Low

Plant compounds with antioxidant activity. Slightly protective at low doses but at high concentrations may worsen hangover via tannin/quercetin reactions.

Sulfites Very Low

Preservatives (SO₂) added to wine and some beers. Common trigger of headaches, asthma, and allergic-type reactions.

Tannins Low

Astringent polyphenols from skins, seeds, barrels. Bind proteins, slow alcohol clearance, and aggravate dehydration-style symptoms.

Sugar Very High

Residual sugar amplifies hangover via blood-sugar swings and dehydration. Liqueurs and cocktails are the main offenders.

Additives Very High

Colorants, flavorings, glycerin, propylene glycol, sorbates. Cheap spirits and ready-to-drinks often hide these in trade-secret formulas.

Captain Morgan is closer to a liqueur than a rum. The “smooth” character is sugar and proprietary flavoring carrying the alcohol — and the morning to match.
