Factor by factor

Congeners Very Low

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

Histamines Very Low

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

Polyphenols Very 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 Very Low

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 Very Low

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

Smirnoff No. 21 (the red-label original) is the world’s volume leader. Don’t confuse it with the company’s flavored sub-brands, which carry sugar, citric acid, and artificial coloring.
