Factor by factor

Congeners 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 Moderate
▾

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.
