Ever wonder how many carbs are in red wine? Is it keto? In this post, we’re covering everything you need to know about having red wine on keto, including carb count and the best types of wine to keep you on track with your health goals.

There’s nothing quite like that first sip of red wine after a long day. Known for its bold flavors and health benefits, red wine can be enjoyed on its own or paired with steak, cheese or dark chocolate. But if you’re on a keto diet, you may be wondering about the carb content of red wine and whether or not it fits into your low-carb meal plan.
What is Keto?
The keto diet (short for ketogenic diet) is a low-carbohydrate, high-fat diet that has gained popularity over the last decade. By reducing your intake of carbs and increasing your consumption of healthy fats, you can shift your body into a state of ketosis, where it burns fat for energy instead of carbs. With a typical diet, your body uses glucose from carbs as its main source of fuel. However, when carbohydrate intake is limited, the body begins to burn fat instead, resulting in faster weight loss.
To achieve ketosis, most keto dieters try to consume less than 50 grams of carbs per day. On a standard keto diet, 70% of your calories would come from fat, 20% from protein and only 10% from carbs. When you’re new to keto, it can be tricky to figure out which foods to remove from your diet and which ones can safely be included in your daily meal plan.
Is Red Wine Keto-Friendly?
If you’re on a keto diet, you’ll be glad to know that red wine can be enjoyed in moderation. With only 2-5 grams of carbs per serving, it’s easy to enjoy a glass of wine without exceeding your daily carb limit. Dry wines (which contain less sugar) are more suitable for keto than sweet wines.
Even though red wine is low-carb, there are still other factors to consider to ensure your keto efforts are successful. All types of alcohol can slow down the process of ketosis, causing you to burn less fat than you would typically expect on a keto diet. For this reason, it’s always best to consume alcoholic beverages in moderation when following the ketogenic diet.
What Does Red Wine Taste Like?
The taste of red wine can vary depending on the type and origin of the wine, as well as how long it was aged. Another factor affecting the taste of red wine is whether it’s sweet or dry. Generally speaking, red wine is known for its rich, bold flavors, featuring fruity, earthy or even spicy notes. Some common flavors of red wine include berries, plums, cherries, figs and raisins.
Red wine can be described as having a complex flavor profile that can range from fruity and bold, to earthy and subtle. Most wine lovers prefer red wine that has a balance of sweet, sour and bitter flavors. Cabernet Sauvignon, one of the most popular types of red wine, is full-bodied and fruity, without being too sweet.

High-Carb Wine to Avoid

- Cheap wines with added sugar: Some cheaper wines have added sugars or other ingredients to enhance flavor, which can also increase the carb content.

- Flavored wines: Flavored wines, such as fruit wines, may contain added sugars or syrups, which can increase the carb content.
