Factor by factor
Congeners Very High ▾
Byproducts of fermentation (methanol, acetaldehyde, fusel alcohols). Strongly linked to hangover severity; darker, less-distilled spirits carry more.
Histamines Moderate ▾
Produced by bacteria during fermentation/aging. Trigger flushing, headaches, congestion in sensitive drinkers. High in red wine, beer, aged spirits.
Polyphenols High ▾
Plant compounds with antioxidant activity. Slightly protective at low doses but at high concentrations may worsen hangover via tannin/quercetin reactions.
Sulfites Low ▾
Preservatives (SO₂) added to wine and some beers. Common trigger of headaches, asthma, and allergic-type reactions.
Tannins Moderate ▾
Astringent polyphenols from skins, seeds, barrels. Bind proteins, slow alcohol clearance, and aggravate dehydration-style symptoms.
Sugar Very Low ▾
Residual sugar amplifies hangover via blood-sugar swings and dehydration. Liqueurs and cocktails are the main offenders.
Additives Low ▾
Colorants, flavorings, glycerin, propylene glycol, sorbates. Cheap spirits and ready-to-drinks often hide these in trade-secret formulas.
Laphroaig’s medicinal smoke is real chemistry: guaiacols, cresols, and other phenolic compounds. Beloved by some, head-splitting to others.
