Factor by factor

Congeners High

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

Histamines High

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 Moderate

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

Additives Moderate

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

Hennessy VS is well-made but engineered for smoothness — and that smoothness is partly chemistry the body has to clear in the morning.
