For those following a ketogenic diet, navigating the world of alcoholic beverages can be tricky. Unlike some other drinks, choosing keto-friendly wine isn't as simple as looking for "low-carb" or "sugar-free" labels. You need to know which specific varieties to choose and which to avoid. Fortunately, enjoying wine while maintaining ketosis is possible with the right knowledge and moderation.
Understanding Keto and Wine
The keto (ketogenic) diet is a low-carb, high-fat lifestyle with moderate protein intake, designed to promote weight loss, improve health, and increase energy. By significantly reducing carbohydrate intake, the body enters a metabolic state called ketosis, where it begins burning fat for energy. During ketosis, the liver converts stored and consumed fat into ketone molecules, which serve as an alternative fuel source.
While wine can be part of a keto diet, it's essential to understand how alcohol affects ketosis. When you consume alcohol, your liver prioritizes processing the alcohol, temporarily putting other processes, like fat burning, on the back burner. So, while a glass of wine won't necessarily kick you out of ketosis, it can slow down the process.
Key Considerations for Keto Wine
Residual Sugar
The most critical factor in determining whether a wine is keto-friendly is its residual sugar content. Residual sugar is the sugar remaining after fermentation. During the wine-making process, yeasts consume the natural sugars in grapes and convert them into alcohol. Winemakers sometimes halt this process, leaving residual sugar, which impacts the wine's sweetness and carbohydrate content.
Dry wines are the best choice for keto dieters because they contain the least amount of residual sugar. Sweet wines, on the other hand, have the most. A wine is generally considered dry if it contains 10 grams of sugar per bottle or less.

Alcohol Content
Another factor to consider is the alcohol by volume (ABV). Wines with higher alcohol content generally have less residual sugar because more of the sugar has been converted to alcohol during fermentation.
Wine Varieties
Knowing which wine varieties are typically lower in carbs is essential. Here's a breakdown of keto-friendly and non-keto-friendly options:
Keto-Friendly Wines
- Dry sparkling wines: Champagne, Cava, and Prosecco labeled "Brut," "Extra Brut," or "Brut Nature" typically have the lowest amounts of residual sugar, often as little as 1.5 grams of carbs per glass or less.
- Sauvignon Blanc: Despite its light and crisp taste, Sauvignon Blanc is an excellent keto-friendly choice, with around 3 grams of carbs per glass.
- Chardonnay: A full-bodied white wine, Chardonnay contains approximately 3.2 grams of carbs per glass.
- Pinot Noir: This lighter red wine is a good option for any season, with about 3.4 grams of carbs per glass.
- Merlot: A heavier red wine, Merlot has around 3.7 grams of carbs per serving, making it a suitable pairing for steak.
Wines to Avoid
- Dessert wines: These wines can contain anywhere from 5 to 12 or more grams of net carbohydrates per glass.
- Moscato: A sweet wine with high residual sugar.
- Port and Sherry: These are fortified wines and are also high in sugar.
- Riesling: While some Rieslings can be dry, many are sweet and contain higher levels of residual sugar.
- Rosé: Often contains some level of residual sugar to counterbalance acidity.
- Sangria: Typically mixed with high-carb drinks like soda or fruit juice.
- Zinfandel: Naturally high in sugar.
- Wine coolers and frozen wine pops/drinks: These are often loaded with added sugars.
- Cabernet
- Grenache
- Shiraz
Tips for Enjoying Wine on Keto
Moderation
Even with keto-friendly wines, moderation is key. Sticking to one glass a day for women and no more than two glasses a day for men is generally recommended. Remember that a standard serving of wine is typically 5 ounces.
Hydration and Electrolytes
Alcohol can dehydrate you, so it's essential to stay hydrated by drinking plenty of water before, during, and after drinking wine. Additionally, alcohol can deplete electrolytes, so consider supplementing with electrolytes.
Strategic Carb Consumption
If you plan to have a glass of wine, consider strategically managing your carbohydrate intake for the day. Stick to lower-carb foods before and after drinking to help balance your blood sugar.

Be Prepared
When dining out, don't hesitate to ask your server for their driest wine option. If you're unsure, specify that you want a wine that is "not sweet."
Measure Your Pours
When drinking at home, use a measuring cup to ensure you're pouring a standard 5-ounce serving.
Finding Keto-Friendly Wines
Online Retailers
Several online retailers specialize in keto-friendly wines:
- Dry Farm Wines: This subscription service curates wines and lab tests them to guarantee they are low carb and low sugar.
- Revel Wine: Specializes in organic and sulfite-free wines, making it easy to select dry wines.
- The California Wine Club: While not exclusively focused on keto-friendly wines, they are a respected online wine subscription service.
- Palo61: This brand produces its own wines and includes nutrition labels on the bottles.
Researching Wine Labels
Most wine labels don't list standard nutrition facts, so you may need to do some research to learn about a wine's sugar and carb content. Look for the ABV and residual sugar information. You can often find a wine's technical information by searching online for the label along with terms like "residual sugar," "fact sheet," or "tech sheet."
To calculate carbs, multiply the residual sugar level in grams per liter (g/L) by 0.15, which will give you the grams of carbs per 150 ml serving.

Other Alcoholic Beverages on Keto
If wine isn't your preferred drink, other keto-friendly alcoholic beverages include spirits like vodka, gin, and tequila. However, be cautious of cocktails at bars, as they often contain sugary syrups and mixers.
