No, column stills do not run continuously because of the different stages the process requires. The process starts with a wash still, followed by a low wines still, and then a spirit still. The stills must be filled and emptied between stages, and time is needed to get the results the distiller wants.
Also, the key to getting good product is to run the still at the right pace, meaning it would not be efficient if one were to run it continuously. As a result, it is necessary that the stills be monitored and run in batches.

How does a distilling column work?
A distilling column is a process device used to separate the components of a liquid mixture by their volatilities. This process version is known as “distillation” and has been used for many years to separate water from ethanol.
It is an essential component of the distilling process used to make alcoholic beverages, essential oils, and other products. A distilling column works by creating a temperature differential across the column, exposing the mixture to multiple areas at different temperatures.
As the liquid mixture is heated, the more volatile constituents will start to vaporize more quickly and ascend towards the top of the column. As the molecules vaporize, they are subjected to the cooler temperatures at the higher elevations in the column, which causes them to condense again and drop down the column.
This process repeats itself until the components of the feedstock are separated based on their relative volatilities. The various components will collect at different points in the distilling column as liquid or as vapor.
Depending on the process configuration, the distillate can then be used as is, or it can be further treated by condensing the vapors back into liquid.
Can you make whiskey with a column still?
Yes, it is possible to make whiskey with a column still. A column still is a type of still that consists of a series of plates or columns with converging sides, each of which is heated separately by separate sources.
The spirit flows from one column to the next, gradually becoming more pure as impurities are removed, resulting in a high-proof pure spirit. This pure spirit can then be distilled further to create whiskey.
Column stills are often preferred by distillers for creating whiskey because their continuous, efficient distillation allows for more precise control over the flavor and character of the finished whiskey.
In addition, column stills are more cost-effective than pot stills, which makes them an attractive choice for distillers wanting to maximize their profits.
What is the column on a still?
A column on a still is a vertical cylinder that helps in the distillation process. The column is filled with a packing material, such as copper mesh or ceramic Raschig rings, which provides a large surface area for the vapor to come into contact with.
The vapor interacts with the surface of the packing material, which helps to further separate the more volatile components of the liquid. In a traditional pot still, the vapor first passes through the swan neck and then the condenser into the column.
The vapor then rises up the column and interacts with the packing material on its way, eventually exiting the column through the top and entering the condenser where it is cooled and collected into liquid form as the desired distillate.
How does a thump keg work?
A thump keg is a type of specialized beer keg that is designed to help give a beer a more robust flavor and carbonation. It works by utilizing a small amount of sugar, yeast, and water (in some cases, just sugar and yeast) to create a secondary fermentation process that occurs within the keg.
The secondary fermentation produces carbon dioxide and ethanol which carbonate the beer, create new flavor characteristics, and increase the overall intensity of the beer. Additionally, the thump keg is referred to as a “closed system”, meaning that the tank can be fitted with a pressure valve that can keep the carbon dioxide at a consistent level and avoid any excessive foaming.
The amount of sugar and yeast used when making a thump keg can be adjusted to change the carbonation level, flavor characteristics, and alcohol content of the beer. To ensure that the beer is properly carbonated, it is important to keep the thump keg at a consistent temperature and pressure, and to ensure that the mixture within the keg is not disturbed.
Once the desired flavor and carbonation levels are achieved, the resulting beer can be consumed directly from the keg or bottled and stored for later use.
How tall should my still column be?
The height of your still column should depend on what type of still you are building. Generally speaking, the taller your column is, the more efficient the still. For example, if you are building a pot still, you should aim for the tallest column possible within the limits of your setup.
This will create more condensation and a higher alcohol content in the end product. If you’re building a reflux still, the correct height depends on your desired ABV. For home distilling, when aiming for a more flavorful beverage, a shorter column is more than adequate.
However, if you’re aiming for a higher ABV, a taller column will be required. In any case, you should point the top portion of the column away from any openings, such as windows and doors, to avoid the spread of any hazardous fumes.
How do you clean a column still?
Cleaning a column still is an important step in distilling spirits, because it helps to ensure that the final product is of a high-quality. Before you begin cleaning the still, it’s important to make sure that all of the components of the still are in good working order.
Start by checking all of the gaskets, valves and fittings of the still. If any of these parts need replacement, do so before continuing.
Once the still has been checked, you can start the cleaning process. Begin by emptying out any leftover liquid from the top sections of the still. Then, fill up the still with a cleaning solution. Warm water combined with either a disinfectant or a mild alkali is usually a good solution.
If you have manual cleaning rods, you can use these to dislodge any build-up near the top sections and then proceed to do the same towards the condenser section. Alternatively, you can use a pressure washer to clean the inside, if you have one available.
Once the inside of the still has been cleaned and the cleaning solution has been removed, the exterior should be wiped down to remove any residue. Be sure to look out for any signs of corrosion and if you do find any, consult with a professional to determine the best way to handle it.
Finally, once everything is dry and the still has been inspected, it is ready to be used again.
How many columns does the Coffey still have?
The Coffey still is a type of pot still used in whiskey distilling, also known as a patent still or a continuous still. It is typically made up of four or five columns, though some designs may have more columns than that.
The columns are filled with copper or stainless steel plates, which are divided into condenser, rectifier, analyzer, doubler and brewer. The heat source underneath the still is used to control the flow of vapor, which travels from the bottom of the still, up through the rectifier, analyzer and doubler.
The vapor then travels through the condenser, where it condenses and can be collected for distillation. The vapor continues up to the top and into the brewer, which is the final column where it turns into a liquid and is collected.
In total, the Coffey still has five columns – a rectifier, an analyzer, a doubler, a condenser, and a brewer.
Are reflux stills good?
Reflux stills have many advantages, and are a good option for both beginner and experienced distillers. Reflux stills are capable of producing highly consistent, pure alcohol and can do so with relatively few components.
They are also relatively user-friendly and easy to setup and operate. The key to a reflux still’s performance is the reflux column. This device is designed to bring boil-off vapors back into contact with the liquid material while they are moving up through the column, resulting in higher levels of distillate purity.
Reflux stills also require less energy to operate than other stills, making them a more energy efficient distilling option. Once the column is designed and setup properly, reflux stills can reach a remarkable high level of distillate purity while using fewer resources and with less effort than other types of stills.
At what temperature do you run a reflux still?
The actual temperature at which you run a reflux still depend on the type of still you are using and the type of spirit you are distilling. Generally speaking, a reflux still should be operated at a temperature of between 70 and 80 degrees Celsius.
However, if the spirit you are distilling contains a large percentage of water, then the temperature should be slightly lower, to facilitate proper distillation. Different types of stills may require different temperatures in order to adequately reflux the contents.
Spirits with a higher ABV will require a higher temperature than those with a lower ABV. When working with distilled spirits, it is important to monitor the temperature closely, as running at too high a temperature may result in a burnt or unpleasant taste.
At what ABV do you stop distilling?
The ABV (alcohol by volume) percentage is one way to measure the alcohol content of a beverage.
The ABV of a finished distilled product is dependent on many factors including the Mash Bill (grain recipe), initial Brix (sugar content) of the mash, yeast Strains used, fermentation temperature, and length of fermentation.
In general, the higher the ABV of the starting material, the higher the ABV of the final product. However, there are diminishing returns when it comes to distilling for a higher ABV.
For example, increasing the ABV from 40% to 60% might only require a single distillation. However, going from 60% to 80% might require multiple distillations.
The reason for this is that as the ABV of the starting material increases, more and more of the water is boiled off. This leaves behind a higher concentration of alcohol, which means that the vapor that is distilled off is also more alcoholic.
Eventually, you reach a point where the vapor is so alcoholic that it is impossible to distill any further and you are left with a product that is 100% ABV.
How much moonshine will a 20 gallon still make?
The amount of moonshine that a 20-gallon still can make varies depending on a number of factors. However, on average, a 20-gallon still should yield about 10 gallons of moonshine. This is based on typical yields for a “corn mash,” which is the most common type of moonshine due to its affordability, safety, and ease of manufacture.
Other factors can affect the yield of moonshine that a still will produce, such as the purity of the starting materials, the quality of the distillation, and even the user’s experience level with making moonshine.
If a more experienced distiller is using higher quality starting materials and taking extra care during the distillation, the yield can potentially be higher than the average mentioned above. Ultimately, the amount of moonshine that a 20-gallon still can make will depend on the specific distillation and the distiller in charge.
How do you know when distillation is finished?
The distillation process is considered finished when the distillate has reached a predetermined proof, or percentage of alcohol, as set by its intended use. This proof rating can range anywhere from 40% to 95% alcohol.
The distiller can determine when this proof has been reached by taking a hydrometer reading of the distillate. A hydrometer is an instrument that measures specific gravity or the density of a liquid liquid compared to the density of water.
When the specific gravity is the same as the start of the distillation process, that is an indication that it is finished and the distillate has reached the desired proof. Additionally, a still can reach a state of stability at the same point.
This is known as the “flat line” and is also an indication that the distillation is complete.
How do you know when you are done distilling?
The point at which you are “done” distilling is known as the endpoint. The most common of which is to use a hydrometer. A hydrometer is a device that measures the density of a liquid in relation to water.
If you’re using a pot still, the best way to know when you’re done distilling is to have someone else watch the thermometer for you while you watch the hydrometer. When the liquid in the still reaches around 95°C, the incorporations of the components of the liquid will start to change and the hydrometer will start to float higher in the liquid.
As the distillation progresses, the float will rise higher and higher in the liquid until it eventually reaches the point where it starts to slow down and then stop rising altogether. At this point, the distillation is almost complete and you can start to think about slowing down the heat to avoid over-distilling the liquid.
If you’re using a column still, the hydrometer method won’t work as well because thecolumn still recycles the liquid over and over again and the hydrometer will just keep floating higher and higher without reachings the endpoint.
In a column still, the best way to know when you’re done distilling is to take periodic temperature readings of the liquid as it comes out of the still. The temperature will start out low and then increase steadily as the distillation progresses.
As the concentration of the alcohol increases, the boiling point of the mixture will also increase. When the temperature of the liquid starts to level off and then decrease, it means that the majority of the alcohol has been removed from the liquid and you are getting close to the endpoint.
You can also take a sample of the liquid and taste it to see if it is too strong for your liking. If it is, then you know you are getting close to the endpoint.
What does a column still look like?
A column still is a type of distillation apparatus used to distill alcoholic spirits. It is a large vertical apparatus made up of copper plates that allow the vapor of the liquid to pass through and condense, producing a high proof spirit.
The number of plates in a column still often varies and depends on the specific distilling design, but the traditional and most common design has three main sections – the beer column, the vapor column, and the lyne arm.
The beer column acts as a pre-heater to vaporize and start the distillation process. The vapor column slowly increases the purification and concentration of spirit vapors as they pass through each plate.
The last column, the lyne arm, is used to further condense the vapors and collect the spirit that is produced.
A column still can be incredibly tall, depending on the size and production capacity of the distillery, so it is often kept in a separate area of the distillation facility. The top of the column still is known as the top head and houses the condenser, which refluxes the spirit vapors and cools them back into liquid.
At the bottom is the pot still, where the beer is heated and turned into vapor so the distillation process can begin.
The size and design of the column still, as well as the type of distilling facility, can all be different, but the main components, such as the beer column, vapor column, and lyne arm, remain the same.
What are the different types of alcohol stills?
There are four main types of alcohol stills: pot stills, reflux stills, fractionating stills and continuous stills.
Pot stills are the simplest type of still, consisting of a single boiling vessel with a head and tail. These hand-operated stills are best suited for producing drinks like whiskey, brandy and rum. They also work best for producing low-proof drinks like moonshine, as the alcohol content can’t be regulated with just a single still.
Reflux stills are slightly more complex than pot stills, as they include a condenser connected to the head of the still. A reflux still works by condensing the vapors from the boiling liquid and re-circulating them back into the head.
This allows the producer to create more neutral and lighter spirits like vodka, and control the proof more easily than with a pot still.
Fractionating stills are more complex and are typically used in industrial alcohol production. These tall, spires stills have multiple condensers which allow the distiller to capture specific fractions of the distillation run.
With these stills, the distiller can create high-proof alcohol and is able to separate out unwanted flavors and impurities.
Finally, continuous stills are the most complex type of still, and are usually used in large-scale alcohol production. Continuous stills allow for continuous distillation and for more control over the blend and flavor of the resulting alcohol.
These still are used for making higher proof spirits like gin, and for producing lighter beverages like vodka.
What type of still is rum made?
Rum is typically made using a pot still, which is an apparatus used in distilling liquid. It consists of a pot with a heated source beneath it and a condensation pipe for collecting the distillate. The still itself is filled with a fermented mash of sugar cane or molasses, and when heated, it vaporizes the alcohol in the mixture and separates it from the water.
The condensation pipe collects the vaporized alcohol, which is then cooled and collected as rum. The rest of the fermented mash left in the pot is known as the “dregs” and can either be used for further distillation or discarded.
