Choosing the Ingredients

Selecting Corn

When it comes to making corn whiskey, selecting the right corn is crucial. You want to choose a variety that is known for its high starch content, as this will result in a higher alcohol yield during fermentation. Look for corn varieties such as dent corn or flint corn, as they are commonly used in distilling spirits. It is important to source high-quality corn from a reputable supplier to ensure the best flavor and overall quality of your whiskey.

Choosing Yeast

Yeast plays a significant role in the fermentation process, as it is responsible for converting the sugars in the corn into alcohol. There are various types of yeast strains available, each contributing different flavors and characteristics to the final product. It is recommended to use a yeast specifically designed for whiskey production, such as a whiskey yeast or a distiller’s yeast. These strains are selected for their ability to withstand higher alcohol concentrations and produce the desired flavors.

Considering Water

Water is another essential ingredient in whiskey production, and its quality can greatly impact the final product. Ideally, you should use filtered or distilled water to avoid any impurities that may affect the taste of your corn whiskey. Additionally, consider the mineral content of the water, as certain minerals can influence the flavor profile. Some distillers prefer using water from specific sources, such as natural springs or wells, to add unique characteristics to their whiskey.

Mashing Process

Preparing the Corn

Before mashing the corn, it is important to clean and rinse it thoroughly to remove any dirt or debris. Once cleaned, grind the corn into a coarse meal using a grain mill or a food processor. This process breaks down the corn kernels, making it easier for the enzymes to convert the starches into sugars during the cooking stage. Ensuring that the corn is ground to the appropriate consistency is crucial for a successful fermentation process.

Cooking the Mixture

After grinding the corn, transfer it to a large pot or boiler and add the desired amount of water. The water-to-corn ratio can vary depending on the recipe, but a common ratio is around 2 gallons of water per 10 pounds of corn. Slowly heat the mixture while stirring continuously to prevent the corn from sticking to the bottom of the pot. The goal is to bring the mixture to a temperature between 150°F and 160°F and maintain it at that temperature for about 1-2 hours.

Adding Enzymes

To convert the starches in the corn into fermentable sugars, enzymes need to be added during the cooking process. There are two main enzymes used in whiskey production: alpha-amylase and glucoamylase. These enzymes break down the long chains of starch molecules into smaller sugar molecules that yeast can easily consume. Follow the recommended dosage instructions provided by the enzyme manufacturer and stir well to ensure even distribution throughout the mixture.

Allowing Fermentation

Once the cooked corn mixture has cooled to around 80°F, it is ready for fermentation. Transfer the mixture into a fermentation vessel, such as a fermentation bucket or a glass carboy, and add the selected yeast. Ensure that the fermentation vessel is properly sealed and fitted with an airlock to allow carbon dioxide to escape while preventing oxygen from entering. Place the vessel in a warm and dark area, and let the mixture ferment for approximately 4 to 7 days, or until the bubbling activity subsides.


Setting Up the Still

Distillation is the process of separating alcohol from the fermented mixture through evaporation and condensation. To begin the distillation process, set up your still according to the manufacturer’s instructions. Make sure all the connections are secure and that the still is clean and free from any debris. Safety should always be a top priority, so ensure that your still is installed in a well-ventilated area away from any flammable materials.

Heating the Mash

Before turning on the heat, transfer the fermented mixture, also known as the mash, to the still’s pot or boiler. Slowly heat the mash, bringing it to a temperature around 173°F. It is important not to set the temperature too high, as this could result in undesirable flavors or even scorching of the mash. Throughout the distillation process, monitor the temperature closely and make adjustments as needed to maintain a steady and controlled heat source.

Collecting the Alcohol

As the heat causes the alcohol to evaporate, it rises through the still’s column or condenser. The vapor will then condense back into liquid form, known as distillate, as it travels through the cooling system. Place a collection vessel at the end of the condenser to collect the alcohol. It is important to note that the first portion of the distillate, commonly referred to as the “heads,” contains high levels of methanol and other impurities. These initial distillates should be discarded to ensure a clean and safe final product.

Discarding Initial and Final Distillates

Similarly, the last portion of the distillate, known as the “tails,” may contain unwanted flavors and compounds. As the distillation process progresses, the alcohol concentration decreases, and these tails can be more noticeable. It is advisable to collect the distillate until the alcohol concentration reaches a certain desired percentage, known as the “cut.” The remaining tails can be saved for future distillations or discarded.

Aging the Whiskey

Choosing a Barrel

Aging is a critical step in the whiskey-making process, as it allows the spirit to develop complex flavors and characteristics. Choosing the right barrel is essential, as it influences the taste and aroma of the whiskey. Traditional oak barrels are commonly used in whiskey aging due to their ability to impart desirable flavors and aromas. However, there are also other types of barrels, such as charred or toasted barrels, that can add unique nuances to the final product. Consider experimenting with different barrel types to discover your preferred flavor profile.

Preparing the Barrel

Before filling the barrel with your whiskey, it is crucial to properly prepare it. If using a new barrel, rinse it with warm water to remove any loose wood particles. Additionally, consider conditioning the barrel by filling it with water and allowing it to swell for 24-48 hours. This step helps seal any small leaks and ensures the barrel is ready to hold your whiskey without losing any liquid during the aging process. Empty the water from the barrel before filling it with your distilled corn whiskey.

Filling and Sealing

Carefully transfer your distilled corn whiskey into the prepared barrel. Ensure that the barrel is securely sealed to minimize evaporation and prevent oxidation. The whiskey should be filled to the top of the barrel, leaving minimal headspace. Any excess air in the barrel can lead to unwanted oxidation and potentially affect the flavor of the aging whiskey. Once the barrel is filled, it is time to set it aside in a suitable environment for the aging process to take place.

Storing in a Suitable Environment

The environment in which you store your aging whiskey can greatly impact its development. Whiskey benefits from aging in a cool and dark environment with consistent temperatures. Avoid abrupt temperature changes, as they can cause the whiskey to expand and contract, potentially damaging the barrel and affecting the aging process. Ideally, find a location that maintains a temperature range between 55°F and 65°F. Allow the whiskey to age undisturbed for a minimum of two years, although longer aging periods often result in more complex and refined flavors.
