  • Home distillers must be equipped with the proper tools and knowledge to produce quality homemade bourbon while navigating the legal aspects of home distillation.

Ingredients for Making Bourbon

Understanding Grain Profiles

The primary ingredients in bourbon are grains, which contribute to its distinct flavor profile. The grain mixture, or mash bill, consists mainly of corn, rye, and barley, with corn being the dominant grain. Bourbon must be made from at least 51% corn, according to the Federal Standards of Identity for Distilled Spirits. Corn lends a sweet, smooth character to the bourbon.

Rye and barley play crucial roles in the bourbon mash as well. Rye imparts a spicy, complex note, while barley, specifically barley malt, provides enzymes necessary to convert starches in the grains into fermentable sugars. Some bourbon recipes also incorporate wheat as an additional grain, which adds a soft, bready quality to the spirit.

The Role of Yeast in Distillation

Yeast is another key ingredient in bourbon production. It is responsible for fermenting the sugars released from the cereal grains, converting them into alcohol. The choice of yeast strain can significantly influence the final flavor of the bourbon, as different strains produce varying amounts and types of congeners, the compounds that give spirits their individual characteristics.

To make bourbon, start with the following ingredients:

  • 7 lbs of corn maize
  • 1.5 lbs of rye
  • 1.5 lbs of barley malt

Combine these ingredients with 5.5 gallons of water and ferment the mash using a suitable yeast strain.

It is essential to carefully consider the ratio of grains in the mash bill and the choice of yeast to create a flavorful and unique bourbon. As a home distiller, you can experiment with different grain profiles and yeast strains to tailor your bourbon to your personal preference.

Remember to keep the process in accordance with the guidelines for bourbon production and maintain a clean environment during the entire process for the best results. With the right ingredients and attention to detail, you'll have a delicious homemade bourbon to enjoy.

The Bourbon Making Process

The Mash Process

The bourbon making process begins with selecting the right grain mixture for the mash bill. A minimum of 51% corn is required, with the remaining grain mixture usually consisting of malted barley, rye, or wheat. The grains are milled using equipment such as a corona corn and grain mill to break them down for better fermentation. The milled grains are then mixed with hot water to create a mash, which is further heated and monitored using a thermometer to maintain the correct temperature range. Enzymes break down the starches in the grains into sugars, and a precise pH level is maintained to prevent bacteria growth.


Once the mash has cooled down, it is transferred to a fermenting vessel with an airlock to prevent contamination. Distillers yeast or turbo yeast is added to begin the fermentation process. The yeast consumes the sugars in the mash, producing alcohol and carbon dioxide. This process typically takes a few days to a week, and the end result is a liquid called wort, which contains around 8-10% alcohol by volume.


The wort is then transferred to a copper still, usually a pot still, for the distillation process. The still is heated, causing the alcohol to vaporize and separate from the remaining mash mixture. The vaporized alcohol is cooled and condensed back into a liquid, called the distillate. Distillation is often performed multiple times to increase the alcohol purity and concentrate the flavors. During distillation, the distiller separates the heads, hearts, and tails – the hearts contain the most desirable flavors and alcohol content, whereas the heads and tails are usually discarded or redistilled.


The final stage in making bourbon is the aging process. The distilled spirits are transferred into charred American oak barrels to develop their flavors and character over time. The process of aging the bourbon can take anywhere from a couple of years to several decades, depending on the desired result. The charred oak imparts flavors, such as vanilla, caramel, and spices, along with the wood's tannins. Some homemade bourbon makers may opt for toasted oak chips instead of barrels to speed up the aging process for smaller batches. Throughout the aging process, the bourbon is sampled regularly to track its development and determine the optimal time to stop aging and proceed to bottling.

Utilizing proper equipment, a balanced grain mixture, and strict attention to all stages, from mashing to aging, one can create a unique and high-quality homemade bourbon with a distinct flavor profile.

Home Distilling Equipment

When starting the process of making bourbon at home, acquiring the proper equipment is crucial. This section will cover essential hardware for home distilling and ensure that the process runs smoothly.

Essential Hardware

  • Grain Mill: A grain mill is necessary to crush the grains used in the mash bill. A consistent grind helps to extract sugars efficiently during the mashing process.
  • Pot Still: A high-quality copper pot still is ideal for distilling bourbon. Copper is preferred because it helps to remove any unwanted sulfur compounds, resulting in a better-tasting end product. Be sure to choose a pot still that is the appropriate size for your desired production volume.
  • Food Thermometer: Monitoring temperature is crucial at various stages of bourbon production. A reliable food thermometer is vital to ensure correct temperatures are reached and maintained during mashing, fermenting, and distilling.
  • Nut Milk Bags: These bags are useful for separating solids and other particles from the liquid after the mash process. A fine mesh bag allows for easier filtration and leads to a cleaner final product.
  • Funnel: A funnel is needed for transferring liquids both during the process and when bottling the finished bourbon. Be sure to have a food-safe funnel to avoid contamination.
  • Bottling Equipment: When the bourbon is ready for consumption, you will need bottles and caps or corks to store it properly. Glass bottles are the preferred choice as they do not impart any flavors or chemicals to the finished product.
  • Specialized Equipment: While not strictly necessary, there are specific tools that can make the home distilling process more efficient, such as a fermenting bucket or glass carboy, which can help in the fermenting process, and a hydrometer that measures the alcohol content.

Having the proper equipment on hand will make the home distilling process more efficient and lead to a higher quality end product. Remember to clean and sanitize all equipment before use to avoid contamination and off-flavors.

Legal Aspects of Home Distilling

Home distilling is a popular hobby for many people, especially those interested in creating their own bourbon. However, it is essential to understand the legal aspects surrounding this activity to ensure compliance with the law. In the United States, home distilling is subject to specific regulations that vary from brewing beer or making wine.

Federal law in the United States strictly prohibits individuals from producing distilled spirits at home without a license. According to the U.S. Tax and Trade Bureau (TTB), while individuals of legal drinking age may produce wine or beer at home for personal or family use, distilling alcohol for personal home use is not allowed (26 United States Code (U.S.C.) 5042 (a) (2) and 5053 (e)).

Additionally, it is essential to note that state laws in the U.S. also play a role in regulating home distilling. While some states have their own specific laws, they generally align with federal regulations. Therefore, even if a state may allow specific distilling activities, it is vital to remember that federal law takes precedence and upholds the prohibition.

Home distilling enthusiasts interested in following the law can explore other options to gain experience and knowledge. One such avenue is to attend distilling workshops at licensed facilities or join home distilling clubs that have the necessary permits for educational purposes. Another alternative would be to apply for a federal distilling license, although this process can be time-consuming and complex, particularly for individual hobbyists.

In summary, it is crucial to understand the legal implications of home distilling in the United States. Although brewing beer or making wine is allowed within specific parameters set by federal and state laws, distilling spirits such as bourbon requires proper licensing and adherence to the relevant regulations.
