Carbs in Coffee: The Ultimate Guide
Coffee is a beloved ritual for millions of us. It’s the perfect pick-me-up in the morning, a cozy companion throughout the day, and a flavorful way to connect with friends. For many people, embracing a low-carb lifestyle has become a key part of their health journey. But this leaves many coffee lovers wondering: Can we still enjoy our favorite brew without sabotaging our carb goals?
You might be surprised to learn that plain, black coffee is naturally very low in carbs. However, when you add milk, sugar, and those tempting flavored syrups, the carb content can skyrocket! This blog post will help you understand exactly how many carbs are lurking in different types of coffee and explore some clever tricks and swaps for making delicious, low-carb coffee. So, get ready to sip more innovative and enjoy your coffee guilt-free!
Does coffee have carbs or calories?
To understand the carbs in coffee, let’s start at the source—the coffee bean itself. Before they are roasted, coffee beans are green and contain significant carbohydrates. About 40-50 percent of a green coffee bean’s composition comprises carbohydrates. The coffee bean is the coffee plant’s seed, and inside this seed are two cotyledons. Think of cotyledons as little food storage units for the baby coffee plant. They are packed with carbs to provide energy for the seedling to grow until it can produce its food through photosynthesis.
The roasting process transforms green beans into the aromatic brown beans we all know and love. During roasting, heat breaks down many carbohydrates. This is why brewed black coffee has a very low carb count—usually less than 1 gram per cup.
Even though black coffee is naturally low in carbs, how you brew it can lead to some slight variations. For example, cold-brew coffee tends to have slightly more carbs than regular hot coffee. This is because the long steeping process of cold-brew allows more time for the natural sugars in the coffee beans to be extracted. But don’t worry; these differences are usually very small.
Decoding the Carb Content of Popular Coffee Drinks
Regarding carbs in coffee, the simplest brews are your best bet. Black coffee and espresso are naturally very low in carbs, typically less than 1 gram per serving. This is true whether you brew a regular cup of coffee or go for a single shot of espresso. Of course, serving size and brewing methods can cause slight variations, as we talked about earlier.
Now, things get more complex when you venture into the world of milky and flavored coffee drinks. The carb count in these beverages is heavily influenced by the amount of milk and flavored syrups added. For instance:
- A café au lait, a 1:1 mixture of black coffee and steamed milk, can contain around 6 grams of carbs when made with whole milk. But if you swap that whole milk for unsweetened almond milk, the carb count drops to 1 gram.
- Cappuccinos, typically made with a 1:1:1 ratio of espresso, steamed milk, and milk foam, can have around 12-20 grams of carbs in a 16-ounce serving.
- Lattes, with their higher milk content (usually a 1:3 ratio of espresso to milk), can easily contain 10-15 grams of carbs. And if you add a flavored syrup like vanilla or chocolate? Just one ounce of syrup can add a whopping 24 grams of carbs.
- A flat white is similar to a latte in milk content and will have a similar carb count.
Here is a table summarizing the carbohydrate content of coffee drinks, drawing on the information you have provided:
| Coffee Drink | Approximate Carb Count (per serving) | Notes |
| Black Coffee | Less than 1 gram | Serving size and brewing method can cause slight variations. |
| Espresso | Less than 1 gram | Serving size can cause slight variations. |
| Americano | Less than 1 gram | |
| Café au lait | 6 grams (whole milk) | Using unsweetened almond milk reduces carb count to about 1 gram. |
| Cappuccino | 12-20 grams | Typically, a 16-ounce serving. |
| Latte | 10-15 grams | Adding flavored syrup significantly increases carb count (1 ounce can add 24 grams). |
| Flat White | 10-15 grams | Similar to a latte in terms of milk content and carb count. Adding flavored syrup significantly increases carb count. |
| Mocha | 27-44 grams | Typically, a 16-ounce serving. |
| Caramel Macchiato | 30-50 grams | Typically, a 16-ounce serving. |
| Pumpkin Spice Latte | Around 63 grams | Typically, a 16-ounce serving. This drink is often loaded with sugary syrups, significantly increasing the carb count. |
Flavored coffee beverages like mochas, caramel macchiatos, and pumpkin spice lattes are often loaded with sugary syrups. A 16-ounce mocha, for example, can have around 27-44 grams of carbs. And those seasonal favorites? A 16-ounce pumpkin spice latte can have around 63 grams of carbs! So, if you’re watching your carb intake, those fancy coffee creations might be best saved for an occasional treat.
Coffee and the Keto Diet
Let’s talk about coffee and the keto diet. If you’re a coffee enthusiast embarking on a keto journey, you’ll be relieved to know you can still enjoy your daily cup of joe!
Black coffee is a keto-friendly beverage because it contains minimal carbohydrates and won’t disrupt ketosis. A 12-ounce serving of black coffee contains less than 1 gram of carbs. Similarly, a shot of espresso provides about 0.5 grams of carbs.
However, being mindful of your chosen additives is crucial, as they can quickly turn your keto-friendly drink into a carb bomb. Avoid sugar and those tempting flavored syrups, as they can contain many carbs. For example, just one ounce of flavored syrup can add 24 grams of carbs.
Here are some keto-friendly coffee options and tips:
Bulletproof coffee is a popular keto choice. It’s made by blending brewed black coffee with healthy fats like MCT, coconut, or grass-fed butter.
Swap dairy milk for unsweetened almond or coconut milk, which are lower in carbs.
Sweeten your coffee with keto-approved sweeteners like stevia or monk fruit.
Look for sugar-free syrups and flavorings to add a touch of flavor without the extra carbs. However, check the labels carefully, as some sugar-free options may still contain hidden carbs.
Remember, the key to enjoying coffee on a keto diet is to keep it simple and avoid those high-carb additions.

The Science of Coffee, Carbs, and Metabolism
Even though coffee beans naturally contain carbohydrates, as seen in green coffee beans, where they represent 40-50% of the chemical composition, the roasting process significantly reduces the carb content. This explains why brewed black coffee has a negligible impact on blood sugar and insulin levels, typically containing less than 1 gram of carbs per 12-ounce serving.
Caffeine, a key component of coffee, plays a fascinating role in metabolism. It acts as a stimulant, potentially increasing metabolic rate and promoting the use of fat for fuel, which aligns with the goals of a ketogenic diet. Some research suggests that caffeine may contribute to increased ketone production, but further studies are needed to confirm this. Please note that this paragraph includes information not from the provided sources, and you may want to verify it independently.
Beyond its caffeine content, coffee itself may benefit glucose and insulin response. Some studies indicate that coffee consumption, independent of additives, might improve insulin sensitivity, which is particularly relevant for individuals with diabetes or prediabetes. However, more research is necessary to fully understand the complex relationship between coffee and blood sugar regulation.
Conclusion
Coffee can be part of a healthy, low-carb lifestyle. Whether you’re following a ketogenic diet or simply watching your carb intake, you can still enjoy your daily cup of joe without derailing your goals.
Here are some key takeaways to help you navigate the world of low-carb coffee:
- Plain black coffee and espresso are virtually carb-free. The minimal carb content comes from the roasting process, which breaks down the carbs naturally present in coffee beans.
- Be mindful of additives. Milk, sugar, flavored syrups, and whipped cream can quickly turn a low-carb coffee into a high-carb treat. Opt for unsweetened milk alternatives, keto-friendly sweeteners, and natural flavor enhancers to keep the carb count in check.
- Brewing coffee at home gives you maximum control over ingredients and helps save money. Experiment with different brewing methods and low-carb customizations to find your perfect cup.
