Casamigos Blanco
Jalisco, Mexico
Known for a sweet, vanilla-forward profile that many reviewers attribute to additives within the 1% allowance. That is a tasting impression, not a test result. It was not on the independent additive-free list when that list was last published in October 2024.

Factor by factor
Congeners Low ▾
Byproducts of fermentation (methanol, acetaldehyde, fusel alcohols). Strongly linked to hangover severity; darker, less-distilled spirits carry more.
Histamines Low ▾
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 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 Moderate ▾
Residual sugar amplifies hangover via blood-sugar swings and dehydration. Liqueurs and cocktails are the main offenders.
Additives High ▾
Colorants, flavorings, glycerin, propylene glycol, sorbates. Cheap spirits and ready-to-drinks often hide these in trade-secret formulas.
Casamigos is the bottle people most often name when they talk about sweet tequila. Mexican rules allow up to 1% caramel, oak extract, glycerin or sugar syrup in 100% agave tequila, but no published test shows what is in Casamigos, so its additive score here rests on its profile rather than proof (what the 1% allows).
Casamigos Blanco questions
Is Casamigos Blanco gluten-free? ▾
Yes. Casamigos Blanco is gluten-free, with no wheat, barley or rye at any stage.
What proof is Casamigos Blanco? ▾
Casamigos Blanco is 80 proof, which is 40% alcohol by volume.
Does Casamigos Blanco give you a bad hangover? ▾
Casamigos Blanco scores 5/10 on the SpiritFacts Hangover Index, against 4/10 for tequila overall. The main drivers are its additives.
Is Casamigos Blanco additive-free? ▾
Not confirmed. Casamigos Blanco was not on the Additive Free Alliance list, the independent list started by Tequila Matchmaker, when it was last published in October 2024, and that list has been empty since. Mexican rules let tequila contain up to 1% caramel colour, oak extract, glycerin or sugar syrup by weight, and the tequila regulator (CRT) does not allow "additive free" on labels, so the bottle itself cannot tell you.
Is Casamigos Blanco vegan? ▾
Yes. Casamigos Blanco is listed as vegan, with no animal-derived ingredients or fining agents.
