REFERENCE
A glass of dry wine is one of the lower-carb drinks going — most of the carbs are leftover grape sugar, so the drier the wine, the fewer carbs. Here's every common style ranked from the fewest carbs to the most, per glass and per bottle.

6 of 9 styles come in under 5g of carbs per glass — the keto-friendly end of the scale.
9 common styles, sorted from the fewest carbs to the most. The band is derived straight from the carbs in a standard 5 oz glass.
| Wine | Carbs / glass | Carbs / bottle | Band |
|---|---|---|---|
| Champagne / sparkling (Brut)Brut sparkling is the lightest common pour — bone-dry, so it's nearly all alcohol calories. | 1.5g | 7.6g | Keto-friendly |
| Dry white (Sauvignon Blanc, Pinot Grigio)Crisp dry whites are a touch lower than red — slightly less alcohol and almost no sugar. | 3g | 15.2g | Keto-friendly |
| Chardonnay (full-bodied white)Oaked, riper whites carry a bit more alcohol, so they land close to a red. | 3.2g | 16.2g | Keto-friendly |
| Dry red (Cabernet, Merlot, Syrah, Malbec)Most reds sit around 125 calories a glass — the higher alcohol does most of the work, with very little residual sugar. | 3.8g | 19.3g | Keto-friendly |
| Rosé (dry)A dry rosé is roughly white-wine territory; off-dry pink styles climb with their sugar. | 3.8g | 19.3g | Keto-friendly |
| Prosecco (extra dry)Lower alcohol than Champagne, but a little more residual sugar evens it out. | 4g | 20.3g | Keto-friendly |
| Off-dry white (Riesling, Moscato)Lower in alcohol, but the residual sugar pushes the calories back up. | 10g | 50.7g | Moderate |
| Fortified (Port, Madeira, Sherry)High alcohol plus sugar makes fortified wine the most calorie-dense — a 2–3 oz pour is typical. | 14g | 70.9g | Higher-carb |
| Sweet dessert wine (Sauternes, late harvest)Rich and sweet — usually poured in a smaller 2–3 oz glass, so pick that serving for a realistic count. | 18g | 91.2g | Higher-carb |
Each style shows the typical carbohydrate in a 5 oz (148 ml) glass and the same figure scaled to a full 750 ml bottle. Dry wine is fermented until almost no sugar is left, so nearly all its carbs are residual sugar — which is why dry reds, dry whites, and brut sparkling sit lowest and sweet or fortified styles sit highest. The band (Keto-friendly, Moderate, or Higher-carb) is derived straight from the per-glass carbs by fixed cut-offs, so the ranking can't drift from the grams. Figures are typical published values, not a measurement of any one bottle, and this is general nutrition information, not dietary or medical advice. Last reviewed 2026-10-06.
One rule: drier means lower carb
Carbs in wine are almost all residual sugar. A bone-dry red, white, or brut sparkling keeps very little, so it lands lowest; a sweet dessert or fortified wine keeps its sugar on purpose, which is what makes it taste sweet and pushes its carbs to the top. Alcohol adds calories but no carbohydrate, so a higher-alcohol dry wine can still be a low-carb pour.
Counting more than carbs?
See the calories and standard drinks in any pour, or how the alcohol content stacks up style by style.
Brut sparkling wine (Champagne, Cava, or dry Prosecco's drier cousins) is typically the lowest, at roughly 1–2 grams of carbohydrate per 5 oz glass, because it's fermented bone-dry. Dry whites like Sauvignon Blanc and Pinot Grigio and dry reds like Cabernet or Merlot are close behind at about 3–4 grams a glass. The sweeter the wine, the more carbs it carries — so 'dry' on the label is the single best signal for low carb.
Dry wine is one of the lower-carb alcoholic options: a glass of dry red, dry white, or brut sparkling is usually only about 2–4 grams of carbohydrate, so it can fit a low-carb or keto approach in moderation. Off-dry, sweet dessert, and fortified wines (Port, late-harvest) carry far more — 10 to 18 grams or more a glass — so they're the ones to watch. This is general nutrition information, not dietary or medical advice; your own targets are what matter.
A standard 5 oz (148 ml) glass of dry wine is typically 2–4 grams of carbohydrate — dry reds and whites land around 3–4 grams, brut sparkling closer to 1–2. Off-dry whites run about 10 grams, and sweet dessert or fortified wines climb to 14–18 grams or more. The carbs come almost entirely from residual sugar left after fermentation, which is why a drier wine is almost always a lower-carb one.
Sweet dessert wines (Sauternes, late-harvest Riesling and the like) are the highest, at roughly 18 grams of carbohydrate per glass, followed by fortified wines like Port and sweet Sherry at around 14 grams, then off-dry whites such as a sweeter Riesling or Moscato near 10 grams. These styles keep a lot of residual sugar on purpose, which is exactly what makes them taste sweet — and pushes their carb count well above a dry wine's.
Yes, almost always. Carbs in wine are overwhelmingly residual sugar — the grape sugar left over when fermentation stops. A fully dry wine has been fermented until very little sugar remains, so it lands at the bottom of the carb scale, while a sweet wine keeps its sugar by design and lands at the top. Alcohol adds calories but not carbohydrate, so a higher-alcohol dry red can still be a low-carb pour.
