Chardonnay
Burgundy, California, Worldwide
Style varies hugely — unoaked Chablis is among the cleanest wines, while heavily oaked California Chardonnay picks up barrel tannins and lactic compounds from malolactic fermentation.

Factor by factor
Congeners Low ▾
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 Low ▾
Plant compounds with antioxidant activity. Slightly protective at low doses but at high concentrations may worsen hangover via tannin/quercetin reactions.
Sulfites High ▾
Preservatives (SO₂) added to wine and some beers. Common trigger of headaches, asthma, and allergic-type reactions.
Tannins Low ▾
Astringent polyphenols from skins, seeds, barrels. Bind proteins, slow alcohol clearance, and aggravate dehydration-style symptoms.
Sugar Low ▾
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.
Chardonnay’s hangover load depends entirely on style. Crisp unoaked = light. Buttery oaked = closer to red wine territory.
