Lowest-Carb Hard Seltzers 2026: 25 Brands Ranked by Carbs, Sugar & ABV (Keto Picks)
Every major hard seltzer and vodka soda ranked by carbs per 12 oz can, with sugar, calories and ABV checked against current labels: the 0g tier (Michelob Ultra Organic, Cutwater, Canteen), the 2g mainstream cans (White Claw, Truly, Bud Light), and the juice-based ones to watch (High Noon 4–5g, NUTRL, PRESS).

Hard seltzer became the default low-carb drink for a reason: most cans carry about 2g of carbs and 100 calories, far less than beer, wine, or any mixed drink with juice or soda. But the spread across brands is wider than the marketing suggests — from a genuine 0g/0g-sugar tier to juice-based cans at 4–5g and one "seltzer" at 7g. Here are 25 of them, ranked by carbs per 12 oz can, with sugar, calories and ABV checked against each brand's current label in September 2026 (where a brand's number changed over the years, we list the current label and note the old one).
The lowest-carb hard seltzers are the 0g tier: Michelob Ultra Organic Seltzer (0g carbs, 0g sugar, 80 cal) and the vodka sodas — Cutwater and Canteen (0g, 0g sugar, 99 cal). Smirnoff Zero Sugar, Nectar and Crook & Marker follow at about 1g. The mainstream cans — White Claw, Truly, Bud Light Seltzer, Vizzy and Topo Chico — sit at 2g and 100 calories. High Noon, made with real vodka and real juice, is the one people underestimate: its current labels read 4.2–5.1g per can depending on flavor, roughly double the mainstream seltzers, though still keto-workable. NUTRL and PRESS are the other two to watch.

Figures are per 12 oz (355 ml) can in the brand's core flavors, from the brand's current nutrition page or a label transcription. "—" means the brand doesn't disclose sugar. Fruity line extensions ("lemonade," "iced tea," "margarita"-style cans) usually add a few grams, so check the specific can.
The 0g tier: vodka sodas and organic seltzers
If you want a can that is genuinely zero, look for the ones built from spirit + soda water rather than fermented sugar + juice: Cutwater Vodka Soda, Canteen Vodka Soda, and Michelob Ultra Organic Seltzer all publish 0g carbs and 0g sugar. Regional and semi-retired options (San Juan, Playamar, Bon & Viv) are 0–2g too, but harder to find. Two things to notice on the label: the 0g cans are sweetened with stevia or nothing at all, and the "real juice" cans (High Noon, NUTRL) are never 0g even when they say "no sugar added" — NUTRL's Real Juice line is 0g sugar but 4.4–5g carbs.
High Noon, Corona and the numbers that changed
Two brands moved while the internet's tables stood still. High Noon's older labels showed 2.3–2.9g per can and many sites still repeat that; the brand's current pages list 4.2g (Pineapple), 4.3g (Lime), 4.5g (Raspberry) and 4.8g (Passionfruit) for Vodka Seltzer, and 4.3–5.1g for the Tequila Seltzer line — all 100 calories, 4.5% ABV. Corona Hard Seltzer launched in 2020 at 90 calories and 0g; the current lineup is 100 calories and 3g for most flavors (2g for Spicy Pineapple and Mandarin Starfruit). Neither change breaks keto, but if you drink four High Noons at a tailgate you have spent 17–19g — nearly a strict-keto day — not the 10g the old tables imply.
Why hard seltzer is so low in carbs
Hard seltzer is essentially carbonated water, alcohol, and flavoring. Unlike beer — which is brewed from grain and retains residual malt carbohydrates — most seltzers are fermented from cane sugar that's almost fully converted to alcohol, leaving little behind. The result is a drink with the alcohol of a light beer but a fraction of the carbs.
The one nuance is how the alcohol gets there. Brands like High Noon skip fermentation entirely and blend real vodka with fruit juice. That tastes cleaner to many people, but the juice adds a small amount of natural sugar — which is why High Noon's current labels read 4–5 g per can — roughly double a fermented-sugar seltzer like White Claw. Vodka sodas with no juice (Cutwater, Canteen) go the other way: real vodka plus plain soda water, so they land at 0 g.
Hard seltzer vs. other drinks on keto
- Hard seltzer / vodka soda: 0–2g carbs per can for most brands (juice-based cans 4–5g) — among the best choices.
- Light beer: ~3-7g per 12 oz. See our low-carb beer ranking for the lowest options.
- Dry wine: ~3-4g per 5 oz glass.
- Spirits (vodka, gin, whiskey) neat or with soda: ~0g carbs — the lowest of all, as long as you skip sugary mixers.
- Regular cocktails, margaritas, and sodas: 15-40g+ carbs — save these for higher-carb days.

The catch: alcohol still slows fat-burning
A near-zero-carb can is great, but alcohol isn't free on keto. Your liver treats ethanol as a toxin and prioritizes clearing it over burning fat, so fat loss pauses while the alcohol is processed — even with a 0g seltzer. You also tend to feel intoxication faster on a low-carb diet. The practical takeaway: hard seltzer is the smartest drink for staying in ketosis, but moderation still matters. Hydrate, and don't count the alcohol calories as "free."

Frequently asked questions
- How many carbs are in a hard seltzer?
- Most mainstream hard seltzers have about 2g of carbs and 100 calories per 12 oz can (White Claw, Truly, Bud Light Seltzer, Topo Chico, Vizzy). A tier of vodka sodas and organic seltzers comes in at 0g (Michelob Ultra Organic Seltzer, Cutwater, Canteen). Juice-based cans run higher: High Noon's current labels show 4.2–5.1g depending on flavor, and PRESS is 7g.
- What is the lowest-carb hard seltzer?
- Michelob Ultra Organic Seltzer (0g carbs, 0g sugar, 80 calories, 4% ABV) is the lowest of the big-brand seltzers. Cutwater Vodka Soda and Canteen Vodka Soda are also 0g carbs and 0g sugar at 99 calories (5% ABV). Smirnoff Zero Sugar Seltzer, Nectar and Crook & Marker sit at about 1g.
- Is hard seltzer keto-friendly?
- Yes. At 0–2g of carbs per can, hard seltzer and vodka sodas fit easily within a keto budget of 20–50g net carbs per day, which makes them among the best alcohol choices on keto. Juice-based cans (High Noon, NUTRL) at 4–5g still fit but count faster. Alcohol itself pauses fat-burning while your body metabolizes it, so moderation matters even at 0g.
- Are White Claw and Truly low carb?
- Both are low carb: White Claw has 2g of carbs, 2g of sugar and 100 calories per 12 oz can (5% ABV); Truly has 2g of carbs, 1g of sugar and 100 calories (5%). Truly Lemonade is 3g. White Claw Surge is also 2g but 8% ABV and about 160 calories per 12 oz.
- How many carbs are in a High Noon?
- More than most seltzers. High Noon's current nutrition labels list 4.2–4.8g of carbs and 2.3–2.7g of sugar per 12 oz Vodka Seltzer (Lime 4.3g, Pineapple 4.2g, Passionfruit 4.8g) and 4.3–5.1g for the Tequila Seltzer line, all at 100 calories and 4.5% ABV. Older third-party listings show 2.3–2.9g, which appears to be a legacy label. The carbs come from the real fruit juice.
- Does hard seltzer break ketosis?
- The carbs in a hard seltzer (0–2g for most brands) won't break ketosis on their own. Your liver does prioritize clearing alcohol over burning fat, so fat loss pauses while the alcohol is processed — you stay in ketosis, but progress slows for a few hours. Drink in moderation and hydrate.
- Is Corona Hard Seltzer really 0g carbs?
- Not anymore. The original 2020 label was 90 calories and 0g carbs, but Corona's current lineup lists 100 calories and 3g of carbs for most flavors (Citrus Lime, Watermelon Lime, Blackberry Citrus, Raspberry Lemon, Blueberry Acai, Strawberry Kiwi) and 2g for Spicy Pineapple and Mandarin Starfruit. The Seltzerita line is 130 calories and 4g.
