Yes, a column still is still a type of reflux still. A reflux still is essentially a distillation apparatus that can be used to purify liquids by vaporizing, cooling, and condensing vapors created by boiling liquid within the still.
A column still is a specific type of reflux still that features an internal condensing and vaporizing column. Next to the inner column, there are often several trays where the vaporized alcohol condenses and falls down for collection.
This type of reflux still creates several distillates, with the help of the reflux action, and allows for a more pure product to be collected at the end. However, the reflux action that occurs in a column still means that the distillate also takes longer to produce compared to other types of reflux stills.

What does reflux still mean?
Reflux still is an arrangement of two or more vessels connected to each other with a tube. This arrangement is used for the distillation of liquids. A typical reflux still contains the main distillation vessel (the pot still), a water-cooled condenser attached to the top of the still, and a reboiler located in the bottom of the pot still.
Through the process of distillation, liquid is vaporized in the pot still and then condensed into a liquid within the condenser, which is collected in the receiver or collection vessel. The reboiler serves as a source of heat to vaporized the liquid in the pot still, while the condenser is used to cool down the vapor and condense it back into a liquid.
This process can be repeated any number of times to increase the purity of the liquid. Reflux stills are commonly used to produce ethanol, essential oils, alcoholic beverages, and various pharmaceutical products.
How a reflux column works?
A Reflux Column is a type of distillation process used in the Oil & Gas, and petrochemical industries. It is used to separate heavier hydrocarbons and condense them into a liquid form. The key feature of the Reflux Column is its ability to maintain a liquid section or stage, where vapor and liquid can coexist.
This allows lightweight molecules to vaporize from the liquid and travel back up the column, condense, and return to the base as a liquid, thus maintaining a continuous vapor-liquid equilibrium. Heat is introduced at the base of the column, causing the liquid to boil.
The vapor then ascends the column and condenses as it cools. The condensed liquid is then fed back to the bottom of the column through a reflux drum. The reflux drum separates the liquid from the vapor, allowing the vapor to continue up through the column.
As the vapor travels through the trays it passes through ports known as tray slots which allow just the right amount of vapor to vaporize out to the atmosphere, while the lighter components are vaporized and condensed back into the column.
This cycle continues until the desired separation has been achieved.
Can you make bourbon with a reflux still?
Yes, you can make bourbon with a reflux still. The main differences between a reflux still and a pot still are how they are set up and how they distill the alcohols. A pot still is an open-top container filled with liquid that is condensed using heat.
This type of still only produces one distillation pass. On the other hand, a reflux still is composed of several plates or bubbles and uses a temperature gradient to condense and re-distill the alcohols multiple times.
This results in a much higher purity and higher alcohol content.
To make bourbon with a reflux still, you will start by mashing up grains such as corn, wheat, and barley and soaking them in hot water. This process will create a wort or beer. Yeast is then added to the wort and will ferment the sugars in the wort into alcohol.
Once the fermentation has been completed, the alcohol is then heated in a reflux still. As the alcohol is heated, it will pass through the several plates of the reflux still, resulting in a high-purity alcohol.
The alcohol can then be aged in charred oak barrels before being bottled and ready for sale.
Can you make whiskey in a column still?
Yes, a column or continuous still can be used to make whiskey. The distillation process for whiskey production typically employs a two-stage distillation process. In the first stage, the fermented liquid is run through a pot still.
The liquid is heated in the pot and the alcohol and other volatile components in the liquid vaporize, rising from the pot into a condenser where the vapor is cooled and liquid alcohol is collected. This is known as batch distillation.
In a second stage, the liquid from the pot still is run through a column still, where the liquid is heated and the alcohol vaporizes and is condensed and collected. This process of double distillation yields an alcohol that is higher in proof and smoother in flavor than what could be produced in a pot still after a single round of distillation.
The result of the second distillation is typically called ‘low wines’ and is often used as the base for additional rounds of distillation to create a spirit such as whiskey.
What happen if I increase reflux in distillation?
If you increase the reflux used in distillation, you likely will see an increase in the purity of the product produced. This is because reflux creates an equilibrium between the vapor and liquid phases in the still.
This suspension allows the vapor and liquid to constantly re-circulate, which helps maximize the separation of components in the liquid being distilled. The increased interactions between the vapor and liquid phases due to increased reflux usually results in a product with a higher purity, as more of the impurities can be removed from the liquid.
It is important to note, however, that increasing the reflux too much can actually lead to a lower product purity as the re-distillation of the liquid can sometimes cause additional impurities to be created.
In addition, increased reflux usually requires a longer distillation time since it requires more energy to circulate the liquid and vapor.
What is the difference between distilling and refluxing?
Distilling and refluxing are both process used to separate liquids based on their boiling points. Distilling is the process of turning a liquid into a gas and then recondensing it back into a liquid, while refluxing is the process of repeatedly bringing a liquid back to the same point of evaporation, forcing it to separate into different components.
Distilling is performed in a heated chamber, or flask, and the heated liquid is allowed to evaporate into a vapor. The vapor then passes into a condenser, which cools it back down into a liquid. Different compounds have different boiling points and as such, the vapor heat levels need to be monitored and adjusted to maintain the correct temperature for the desired compound.
The collected liquid is then known as the distillate.
Refluxing is similar to distilling in that it uses the same heated chamber and condenser, except the heated liquid is bubbled back into the chamber while continually evaporating and condensing. This constant exchange of vapor and liquid results in the separation of components in the liquid.
Refluxing is typically done at a lower temperature than distilling and requires less adjustment of the heat source. The collected liquid is then referred to as the refluxate.
In conclusion, the main difference between distilling and refluxing is that distilling uses single fraction evaporation, while refluxing uses multiple fraction evaporation to achieve separation of different components.
This means that distilling requires constant supervision and heat adjustments to ensure that desired components are collected, while refluxing requires less control and heat adjustments as the liquid and vapor constantly cycle in the chamber.
Does bourbon have to be made with limestone water?
No, bourbon does not have to be made with limestone water although historically it was made in the area where limestone water was plentiful. Limestone water is known for its high mineral content, including calcium and magnesium.
It is thought to produce a smoother spirit, which is why it was used in bourbon production as early as the 1800s. Limestone water also helps remove impurities from the alcohol, resulting in a cleaner flavor.
While limestone water is not a requirement for bourbon production, some specialty bourbon distilleries still use it today. The main requirement for bourbon is that it must be made from at least 51% corn, aged in charred, new oak barrels, and be produced in the United States.
As long as those basic standards are met, there is no requirement to use limestone water.
How much will a 10 gallon still produce?
A 10 gallon still should be able to produce around 5-6 gallons of alcohol at the end of a single distillation run. Ultimately, your still’s yield will depend on the quality of the spirit being distilled, and the efficiency of the still being used.
If the spirit is of a high quality and the still is efficient, you could expect higher yields, up to 8 gallons in some rare instances. Additionally, the length of the spirit run can also impact the yield.
For instance, a short run of spirit may produce low yields, whereas a longer run will extract more flavor, oils, and alcohol from the mash and boil, resulting in higher yields. Finally, other factors such as temperature, pressure, the cooling rate of the condenser, and the quality of the head and cuts made during the distilling process can all influence how much is yielded from a distillation run.
What is the material for a still?
Traditionally, a still is an apparatus used to distil liquid mixtures by heating them to separate the components. Still designs can vary, but all consist of four basic parts: a vessel, a heating system, condenser, and an outlet.
The vessel is where the distilling is done – it must be heat resistant and not leak, so metals such as stainless steel or copper are the most common. The heating system must be able to reach temperatures high enough for the distillation process – usually this is done with either direct heat, either from a burner or by way of steam, or sometimes indirect heat from a recirculating liquid, often water or oil.
The condensing element is then used to cool the vapors from the distillation, which causes them to condense as a liquid – this is generally done via an external heat exchanger, or condenser. The outlet is then used to carry away the condensed liquids.
In short, the material for a still is typically stainless steel, copper, or other metals, with a heating system and a condenser.
What stills do they use on Master Distiller?
The Master Distiller has a number of skills to help them create modern and traditional spirits through the art of distillation. These include the ability to create designs, experiment with flavors and aromas, detect any off-flavors, and assess spirit aging.
The first skill to understand is the process of distillation. This is the process of using heat to separate alcohol from other components of a spirit, such as water and impurities. While basic distillation carries out the task of separating alcohol from other materials, some distillers use advanced techniques of steam distillation to further refine their spirits and increase their alcohol content.
Once the spirit is produced, the Master Distiller must have the discretion to assess whether the spirit is ready for consumption or requires more aging. The distiller must also have the knowledge to detect any off-flavors that may have been created during the process and be able to assess the quality of the spirit.
The Master Distiller must also understand how flavors interact, as they must be able to create custom spirits that pair well with one another. They must understand traditional recipes and be able to put a unique spin on them by experimenting with ingredients and flavors to create unique profiles.
In addition to being able to assess the quality of a spirit, the Master Distiller must also be able to create visually-appealing designs and recipes.
Overall, the Master Distiller must be an experienced and talented professional who understands the craft of distillation and the principle of modern spirits production. They must have an impressive combination of skills, ranging from distillation techniques to flavor assessment and creativity, to ensure that their spirits are of the finest quality.
What makes a good moonshine still?
One of the most important aspects of moonshine stills is that they are made of high-quality materials. This includes the pot, the condenser, and the tubing. The pot should be made of stainless steel or another non-reactive metal.
The condenser should be made of copper. The tubing should be made of food-grade materials.
Another important aspect of moonshine stills is that they are designed to be airtight. This is important because the still needs to be able to maintain a consistent temperature. If the still is not airtight, then the temperature will fluctuate, which can cause the moonshine to be less potent.
Finally, moonshine stills need to be large enough to produce a significant amount of moonshine. This is important because the larger the still, the more moonshine that can be produced. This can be important for those who want to sell their moonshine or for those who want to make a lot of moonshine at once.
Can you use a reflux still to make whiskey?
Yes, you can use a reflux still to make whiskey. A reflux still is a type of distillation apparatus that is used to purify and refine alcoholic liquids. Reflux stills are praised for their ability to separate and purify alcoholic liquids in a very effective manner, and this makes reflux stills ideal for the production of high-quality whiskey.
To make whiskey with a reflux still, you’d first start by mashing grains and then distilling the resulting fermented liquid in the still. The reflux still works by re-condensing alcohol vapors and guiding them to the top of the still, where the alcohol can be collected in its most concentrated form.
You would then combine the collected product with other ingredients, such as caramel color or oak chips, to create your desired product. Some reflux stills feature a separate refrigerator chamber that helps to capture the purest, most notable compounds that give whiskey its unique flavor and aroma.
What type of still is used for bourbon?
Bourbon is typically made in a type of still known as a continuous still, more specifically referred to as a Coffey or column still. This type of still allows distillers to distill the mash of corn, rye, and barley multiple times, creating a spirit that is pure and high in alcohol.
In addition, a continuous still produces fewer congeners and flavoring agents, resulting in a cleaner-tasting spirit. The vapors from the still are condensed and then aged in charred oak barrels, giving Bourbon its signature flavor and amber hue.
At what temperature do you stop collecting with a reflux still?
This is a difficult question to answer because it depends on the type of liquid being distilled and the desired end product. Generally speaking, the temperature of a reflux still should be monitored and adjusted during the distillation process, not determined ahead of time as a single “magic number”.
For example, when distilling a high-proof (potent) liquor like whiskey, rum, or brandy, you may want to reduce the distillation temperature as the proof level of the distillate surpasses your target.
This ensures that the flavors and aromas that should be present in the final product are extracted and retained. On the other hand, when making a mineral oil or fatty acid, you may want to increase the distillation temperature as the separation occurs, in order to ensure that the substances have been separated completely.
Generally, a reflux still should be operated until the liquid runs clear, unless the aim is to maximize the proof of the distilled liquid. Some distillers use a reflux still until the distillate has reached a proof that is within a few points above their desired result, then stop collecting and move onto a pot still to further increase the proof levels.
Ultimately, you should follow the practices of your particular process and consistently take readings throughout the duration of the distillation process. By regularly testing your distillate, you can make appropriate and informed decisions on how to adjust the temperature in order to create the desired end product.
Are reflux stills good?
Reflux stills can be a great choice for distillation applications that require high-purity alcohol and low congener levels. Depending on the type, they are typically more efficient than standard pot stills and usually involve less oversight and assembly.
They often involve fewer components and can typically reach higher levels of purity than pot stills. In addition, reflux stills are able to take advantage of higher boiling temperature liquids, such as glycol or isopropyl alcohol, for greater purification and higher proof distillate.
That being said, reflux stills are not necessarily “better” than pot stills in all cases. They require the use of electricity, supplies, and equipment to operate. Additionally, because of their greater efficiency, they can use up ingredients more quickly than pot stills.
Furthermore, it takes time to learn the setup and operation technique for running a distillation batch, with reflux stills requiring more expertise over a regular pot still. Ultimately, when looking for a distillation option, one should consider their individual needs, budget, and space when choosing between a reflux still or a pot still.
How long do you let rum ferment?
The fermentation process for rum typically takes between 7 to 10 days, although the exact length varies depending on the desired final product and the temperature of the environment. During the process of fermenting rum, molecules in the sugar are broken down into simple organic compounds, producing the desired flavor and alcohol content.
The fermentation process can be completed with a variety of natural yeasts, including wine, champagne, and distiller’s yeast, each of which will yield a specific flavor profile. In order to optimize the flavors and quality of the distilled rum, it is important to pay close attention to the fermentation process and fermentation time.
Additionally, oxygen introduced during the fermentation process helps break down compounds, improves flavors, and forms smoother rum overall. After the desired fermentation time has passed, the fermented rum is ready to be distilled and aged.
How long does rum last in a decanter?
The shelf life of rum in a decanter depends on the type of rum, and how the decanter is sealed and stored. Generally speaking, most rums will last between 2 and 5 years when stored in a decanter, if it is properly sealed and stored away from direct sunlight.
If a decanter is not properly sealed, air can enter the container and cause oxidation, which can start to impact the taste and quality of the rum after a year. Additionally, light, heat and humidity can also play a role in spoiling the rum.
To maintain optimal taste, it is best to store rum in a cool, dry place away from direct sunlight and drink it within two to three years.
