Understanding Carbohydrates in Wine
On a low-carb or ketogenic diet, monitoring your intake of hidden carbohydrates is crucial, and wine is no exception. The carb content of wine is primarily determined by its residual sugar (RS), which is the leftover sugar after the fermentation process is complete. During fermentation, yeast consumes the sugar from grape juice and converts it into alcohol. The longer the fermentation, the less residual sugar remains, resulting in a drier wine with a lower carb count. Conversely, fermentation is deliberately stopped early for sweeter wines, leaving behind a higher sugar content and a greater number of carbohydrates.
The Dry vs. Sweet Spectrum
For wine drinkers focused on minimizing carbs, understanding the sweetness scale is essential. While a standard 5-ounce glass of dry wine typically contains 1–4 grams of carbs, a sweeter variety can pack 7–14 grams or more. Dry wines taste less sweet because most of the sugar has been converted into alcohol. Sweet wines, such as dessert wines or late-harvest varieties, have a higher concentration of residual sugar, and therefore, a significantly higher carb count.
The Best Low Carb Wine Choices
Choosing the right bottle is easy once you know what to look for. Stick to varieties that are famously dry and low in residual sugar. A breakdown of recommended low carb wine choices by type can be found on {Link: Get Keto get-keto.com}.

The Impact of Alcohol on Ketosis
Alcohol metabolism is prioritized by the body, which can temporarily slow fat burning. Moderation is key to avoid impacting ketosis. The calories in wine come from both alcohol and residual sugar.
Comparison Table: Low Carb Dry Wines vs. High Carb Sweet Wines
| Wine Type | Sweetness Level | Carbs (per 5 oz glass) | Sugar (Residual) | ABV | Example Varieties |
|---|---|---|---|---|---|
| Dry Red | Very Low | ~3-4g | 0-2g | 13-15% | Pinot Noir, Cabernet Sauvignon |
| Dry White | Very Low | ~2-3g | 0-1g | 11-13% | Sauvignon Blanc, Pinot Grigio |
| Brut Nature Sparkling | Zero | 0-1g | <0.9g | ~12% | Champagne, Cava |
| Late Harvest/Dessert | High | 7-14+g | 7+g | 10-14% | Moscato, Port |
| Sweet Red | Medium to High | 5-10+g | 5+g | 8-10% | Sweet Lambrusco, Ruby Port |
Conclusion
Dry red, white, and sparkling wines can be part of a low-carb diet in moderation. Prioritize dry wines due to their low residual sugar and carb content. Avoid sweet and fortified wines. Careful selection and portion control allow for enjoying wine within a low-carb lifestyle. For more information, refer to a guide like Diet Doctor's on alcohol.
