What is bourbon?

Bourbon is a type of whiskey that originated in the United States. It holds a special place in American history and culture and is recognized as a distinct spirit category. 

The name “bourbon” is derived from Bourbon County, Kentucky, where it is said to have been first produced. However, bourbon can be made anywhere in the United States.

To be legally classified as bourbon, the spirit must meet specific criteria defined by the U.S. government. These criteria include the following [1]:

  • Mash Bill: Bourbon must be made from a grain combination that is at least 51% corn. The remaining grains typically include barley, rye, or wheat.
  • Distillation: The spirit must be purified to practically 160 proof (80% alcohol by volume) and move into the keg for maturing at no more than 125 proof (62.5% alcohol by volume).
  • Aging: Bourbon must be aged in new, seared oak barrels. There are no specific requirements for the duration of aging to be called bourbon, but to be labeled as “straight bourbon,” it must be aged for a minimum of two years.
  • No Additives: Bourbon cannot contain any added flavorings, colorings, or other additives. It must be made solely from the grains, yeast, and water used in production.

What does “carb-free” mean?

The term “carb-free” refers to the absence or negligible presence of carbohydrates in a particular food or beverage. Carbohydrates are one of the three major macronutrients, along with proteins and fats, that provide energy to the body.

In the context of a “carb-free” claim, it typically implies that the product contains an extremely low amount of carbohydrates, usually less than 0.5 grams per serving. However, it’s important to note that truly carb-free foods or beverages are extremely rare, as almost all natural foods contain some amount of carbohydrates. 

Therefore, when a product claims to be “carb-free,” it often means that it contains such a minimal amount of carbs that it can be considered negligible for dietary purposes.

What is the carb content in bourbon?

When it comes to determining the carb content in bourbon, it’s essential to understand that bourbon, like any other alcoholic beverage, contains calories and carbohydrates.

While bourbon is not inherently carb-free, it generally contains fewer carbs compared to other alcoholic beverages such as beer or sweetened cocktails.

The exact carb content in bourbon can vary depending on factors such as the specific brand, production methods, and the aging process.

To ascertain the carb content of a particular bourbon, it is necessary to refer to the nutrition information provided by the distillery or consult reliable sources that have conducted carb content analyses.

Carbohydrates in Alcohol

What are carbohydrates and their role in nutrition?

Carbohydrates, along with proteins and fats, are one of the three main macronutrients. They serve as a main source of energy for the body. [2]

Carbohydrates are composed of sugar molecules that can be classified into simple or complex carbohydrates.

Plain carbohydrates, such as glucose and fructose, are quickly digested and consumed by the body, providing a rapid energy source.

Complex carbohydrates in foods like whole grains, legumes, and vegetables consist of long chains of sugar molecules and provide sustained energy due to their slower digestion.

How are carbohydrates present in different alcoholic beverages?

Carbohydrates can be present in alcoholic beverages in various forms. In beer, carbohydrates come from the malted grains used in brewing, primarily barley. Beer can contain significant amounts of carbohydrates, which contribute to its calorie content.

Wine is made from fermented grapes, which naturally contain sugars. The yeast consumes the grape sugars during fermentation, converting them into alcohol. However, some residual sugars may remain in the wine, contributing to its carbohydrate content.

Spirits like bourbon are derived from the fermentation and distillation of grain mash. While distillation removes most of the carbohydrates, trace amounts can still be present in the final product.

The primary source of carbohydrates in bourbon comes from the grain used in its production, particularly corn, which contains natural sugars.

What is the relationship between alcohol and carbohydrates?

Alcohol itself contains calories but is not considered a significant source of carbohydrates. In terms of nutrition, alcohol is considered a different macronutrient from carbohydrates, proteins, and fats. 

When consumed, alcohol is processed differently by the body compared to other macronutrients.

The body metabolizes alcohol as a priority, as it cannot be stored and must be eliminated. This can temporarily disrupt the metabolism of other nutrients, including carbohydrates.

The body prioritizes the breakdown of alcohol, which can potentially affect blood sugar levels and impact the body’s ability to use carbohydrates for energy.

Assessing the Carb Content of Bourbon

What are the factors influencing carbohydrate content in bourbon?

Several factors can influence the carbohydrate content in bourbon. The primary factor is the grain composition of the mash bill. Since corn is the main grain used in bourbon production, it contributes the most significant amount of carbohydrates.

Other factors that can influence carbohydrate content include the fermentation process and the length and conditions of the aging process. The longer bourbon ages, the more complex flavors it develops, but the carbohydrate content may remain relatively stable.

How to analyze the typical ingredients of bourbon?

Bourbon typically contains corn as its primary ingredient, which contains natural sugars. Secondary grains like barley, rye, or wheat are used in smaller quantities, but their carbohydrate contribution is generally less significant.

The specific ratios and types of grains used in the mash bill can affect the overall carbohydrate content of the bourbon.

What are the carb levels between different types of bourbons?

The carb levels between different types of bourbons are generally similar, and the differences in carb content are typically minimal.

Here is a general overview of the carb levels you can expect across different types of bourbons:

  • Straight Bourbon: Straight bourbon, which meets specific aging and production requirements, generally has a carb profile similar to other bourbons. The carb content per serving or volume can range from approximately 0 to 4 grams of carbohydrates, with the majority of the carbs coming from residual sugars from the grains used in the mash bill.
  • High-Rye Bourbon: High-rye bourbons, which have a higher proportion of rye in their mash bill, may have a slightly lower carbohydrate content compared to bourbons with a higher corn content. Rye typically contains fewer carbohydrates than corn, which can contribute to a marginally lower carb level in high-rye bourbon expressions.
  • Wheated Bourbon: Wheated bourbons, where wheat is a primary grain in the mash bill instead of rye, may also have a slightly lower carbohydrate content compared to traditional bourbons. Wheat generally contains fewer carbohydrates than corn or rye, which can significantly reduce carb levels in wheated bourbon.
  • Small-Batch and Single-Barrel Bourbons: Small-batch and single-barrel bourbons can vary in their grain composition and production methods. However, the carb levels among these types of bourbons are typically similar to other bourbon categories, with a range of approximately 0 to 4 grams of carbohydrates per serving or volume.

What is the carb content of famous bourbon brands?

Determining the precise carb content of famous bourbon brands can be challenging as the specific nutritional information may vary between brands and even different expressions within the same brand. 

Additionally, distilleries may not always disclose detailed carbohydrate information on their packaging or websites.

However, I can provide you with a general overview of the carb content of some well-known bourbon brands:

  • Jim Beam: Jim Beam is a popular bourbon brand, but the specific carb content can vary depending on the expression. Generally, bourbon made primarily from corn, like Jim Beam, contains trace amounts of carbohydrates due to the natural sugars present in corn.
  • Wild Turkey: Wild Turkey is another renowned bourbon brand. Like other bourbons, the carb content of Wild Turkey is primarily influenced by the grains used in the mash bill. While specific information may not be readily available, it is likely to contain a minimal amount of carbohydrates.
  • Knob Creek: Knob Creek is known for its robust flavor and higher-proof bourbons. Although specific carb content information may not be easily accessible, it is expected to have a similar carb profile to other bourbon brands.

Although specific carb content information may not be readily available, Basil Hayden’s, like other bourbons, is generally considered to have a lower carbohydrate content due to its grain composition.

What are the other low-carb alternatives to bourbon?

Several options are available if you’re looking for low-carb alternatives to bourbon. Here are some alternatives to consider, along with explanations of their relatively lower carbohydrate content:

  • Clear spirits: Spirits like vodka, gin, or tequila generally have fewer carbohydrates compared to bourbon. These clear spirits are distilled from grains or agave and can be enjoyed straight, on the rocks, or in low-carb cocktails.
  • Light beer: Light beers are typically lower in carbohydrates compared to regular beers. They are often brewed to have fewer calories and reduced carbohydrate content.
  • Dry wines: Dry wines, such as red or white wines with lower residual sugar, generally have fewer carbohydrates compared to sweet or dessert wines. Dry wines are fermented more fully, resulting in lower sugar content.
  • Seltzers and sparkling water: Seltzers and sparkling water flavored with natural essences or infused with fruit flavors can provide a refreshing low-carb alternative to bourbon or other alcoholic beverages. These options are typically carb-free or very low in carbohydrates.


Is it OK to drink bourbon on keto?

Bourbon can be enjoyed on a keto diet in moderation. While it is carb-free or very low in carb count, it’s important to consider the alcohol content and its potential impact on ketosis.

Drinking alcohol can temporarily halt fat burning and may affect weight loss progress. So, if you’re trying to lose weight but can’t avoid drinking bourbon, limiting your alcohol consumption is a smart move.

If you consume bourbon on a ketogenic diet, consider bourbon keto recipes or enjoy bourbon with low-carb mixers, such as diet soda water, to keep your carb intake low.

It’s crucial to drink alcohol, including bourbon, mindfully, within your daily net carbs and calorie limits, and maintain a balanced approach to your overall keto lifestyle.

How many carbs in a shot of bourbon?

A standard shot of bourbon, which is approximately 1.5 ounces (44 ml), typically contains negligible carbohydrates. 

Bourbon is primarily made from grains such as corn, which undergo fermentation and distillation processes that convert the natural sugars into alcohol. 

As a result, the carbohydrate content in bourbon is minimal, ranging from 0 to 4 grams per serving, depending on the brand and specific expression.

To minimize how much sugar you consume, opt for plain bourbon, be mindful of the specific brand and expression you choose, and most importantly, drink responsibly!

How are there no carbs in bourbon?

Bourbon contains little to no carbs due to the fermentation and distillation processes it undergoes during production.

The grains used in bourbon, such as corn, rye, wheat, and malted barley, contain natural sugars. 

However, during fermentation, yeast converts these sugars into alcohol, resulting in minimal remaining carbohydrates. 

Distillation further purifies the spirit, separating alcohol from other components, including carbohydrates. As a result, bourbon ends up with little to no carbohydrates in the final product.

Is bourbon low in sugar and carbs?

Yes, bourbon is generally low in both sugar and carbs. The fermentation and distillation processes in bourbon production convert the natural sugars from grains into alcohol, significantly reducing the sugar content. 

Additionally, the carbohydrate content in bourbon is minimal due to the same processes. However, it’s worth noting that some flavored or infused bourbons may contain added sugars or other ingredients that can increase the sugar and carb content.
