What's in it
Every brand and category carries the same seven factors. Each is graded on an ordinal five-point scale; the CSVs include
both the label (e.g. high) and a numeric _score column (1–5) for analysis.
Byproducts of fermentation (methanol, acetaldehyde, fusel alcohols). Strongly linked to hangover severity; darker, less-distilled spirits carry more.
Produced by bacteria during fermentation/aging. Trigger flushing, headaches, congestion in sensitive drinkers. High in red wine, beer, aged spirits.
Plant compounds with antioxidant activity. Slightly protective at low doses but at high concentrations may worsen hangover via tannin/quercetin reactions.
Preservatives (SO₂) added to wine and some beers. Common trigger of headaches, asthma, and allergic-type reactions.
Astringent polyphenols from skins, seeds, barrels. Bind proteins, slow alcohol clearance, and aggravate dehydration-style symptoms.
Residual sugar amplifies hangover via blood-sugar swings and dehydration. Liqueurs and cocktails are the main offenders.
Colorants, flavorings, glycerin, propylene glycol, sorbates. Cheap spirits and ready-to-drinks often hide these in trade-secret formulas.
The Hangover Index is a 1–10 weighted composite of those seven factors plus typical serving strength. Full grading rules are on the methodology page, and each factor is defined in the glossary.
