14g ethanol at 40% ABV. No sugar, so every calorie here is alcohol.
In its favor
- ✓No added sugar or additives
- ✓Carter-head still, an unusual choice for vodka
What to watch
- !Wheat and barley base, so two gluten grains rather than one
- !Lava-rock filtration is a real process but not a chemistry advantage
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.
Reyka is distilled in a Carter-head still, a design more associated with gin, and filtered through lava rock from the surrounding fields. Both are genuine and both are heavily marketed, so it is worth separating them: the still shapes the spirit, the lava rock is doing what any porous filtration medium does.
The base is wheat and barley. If you are avoiding gluten grains, this is the wrong bottle on this page, and there are four here that are grain-free at source.
