What is a thumper? If you are a brewer or familiar with brewing beer, you may have heard this term before and wondered what it means. I can thank the brewers for coming up with this term, as it describes a great brewing tool or piece of equipment.

What Is a Thumper?

A thumper is a piece of equipment that helps create carbonation in the beer. Generally, it produces carbon dioxide gas in the brewing process. I can make thumpers from various materials, such as stainless steel or copper. They consist of a cylindrical vessel with a conical bottom.

Every brewer knows the importance of carbonation, its role in the brewing process, and the overall flavor and appearance of the beer. Achieving the right level of carbonation takes time and experimentation. However, with the help of a thumper, you can increase the carbonation in your beer, which will give it a nice head and better flavor.

When I drink a soda or sparkling water, the carbonation is what gives it its fizzy bubbles. Therefore, I cannot rule out the importance of carbonation in beer. In fact, carbonation is one of the most important aspects of the brewing process and requires a lot of attention.

History of the Thumper

Thumpers have been around since at least the 1700s and were originally used to help speed up the distilling process by pumping air into the still. The thumper has been part of the brewing process for centuries. It was not until the 19th century that it was dubbed “the thumper.”

The modern version of the thumper did not make its debut until around the late 1800s. This version was much smaller and easier to use and was not attached to a beam or other moving system. It came with a pump that could be manually operated by hand or foot.

A simple step on a pedal would move it up and down, creating carbon dioxide bubbles inside a container filled with beer. An airtight lid covered the whole machine to keep out the oxygen so that it only created bubbles inside. The airtight lid made the thumper popular among homebrewers.

Why the Thumper Was So Popular?

As distillers, the early brewers were always looking for ways to speed up the brewing process. The thumper helped them generate carbon dioxide gas, which helped carbonate the beer to produce a nice head and better flavor.

The thumper was also popular because it was a simple machine that could be easily operated by hand or foot. So, even if you were not a skilled brewer, you could still use the thumper to help carbonate your beer. It is what helped make the brewing process more accessible to more people.

In addition, the thumper was a small and compact machine, which made it easy to store and transport. It could also be used with other brewing equipment, such as a still or mash tun. Today, brewers still rely on thumpers to effectively create carbon dioxide and carbonate their beer.

A Simple Way to Make a Thumper

Making beer is fun and rewarding, and it is even more fun when one understands how to make a thumper. One will need 1/2 inch copper tubing, copper elbow fittings, copper fittings, electrical tape, soldering iron, and solder. I can also use copper fittings with rubber rings.

The first thing I need to do is measure and cut the copper tubing. I will need two pieces of tubing that are each twelve inches long. Next, I need to solder the fittings onto one end of each piece of tubing.

Once the fittings are attached, I need to screw the elbow fittings onto each end of the tubing. These fittings will help connect the thumper to the brewing container. I can then use electrical tape to secure the fittings in place. I are now ready to attach the thumper to my brewing container to help me carbonate my beer.

How to Brew With a Thumper

Brewing with a thumper is a simple process. I first need to heat up my brewing container, which will help the beer to ferment properly. I then add the malt, hops, and yeast to the container. I need to ensure that the thumper is connected to the brewing container and that the carbon dioxide bubbles are going into the container.

A thumper works by passing the wort from the primary fermenter through a tube into a bottle filled with water. The pressure from the wort entering the water forces some of it back through another tube into the primary fermenter, adding oxygen to the wort. The thumper re-condenses and adds carbonation to the beer.

Brewing with a thumper is a great way to improve your beer’s quality and experiment with different flavors. With a little practice, you will be able to create beers that are both delicious and unique. Give it a try today!

How Does a Thumper Help to Create Better-Tasting Beer?

To brewers, a thumper is essential to add to their arsenal because it helps create better-tasting beer. The thumper is used to create carbon dioxide, which is essential for carbonating the beer, and that is why it is so important.

The following are some of the ways a thumper help brewers create a better-tasting beer:

Prevents Oxidation

Another advantage of utilizing a thumper is that it prevents oxidation. When beer is exposed to oxygen, it can spoil and develop an undesirable flavor. Brewers may avoid this issue by sealing their bottles with a thumper.

Adds Carbonation

A thumper also helps to add carbonation to the beer. This is an important step in the brewing process, and it helps to produce a beer that is both flavorful and refreshing. A beer with less carbonation may also be less filling and harmful to your health.

It Helps to Clarify the Beer

Every brewer desires to produce a beer that is both clear and tasty. The thumper can help to achieve this goal by helping to clarify the beer.

When the beer is passed through the thumper, it causes the yeast and other particles to settle out. This results in a beer that is both clear and smooth-tasting.

Add Flavor

A thumper can help add flavor to beer in many ways. One way is by adding carbonation, which helps to bring out the flavor of the malt and the hops. Another way that a thumper can add flavor to beer is by helping to clarify it.

When the beer is clear, it allows the brewer to see all of the different flavors that are in the beer. This helps to produce a more flavorful and complex beer.

Reduces the Amount of Time Needed to Ferment

A thumper can also help to reduce the amount of time needed to ferment beer. It does this by adding carbonation to the beer, which helps to speed up the process.

When the beer is fermented in a thumper, it causes the yeast to become more active. This helps to reduce the amount of time needed for fermentation.

Saves Money

Brewers can also save money by using a thumper. This is because the thumper allows them to produce beer with more carbonation. This means they can use less malt and hops to produce the same results.

Different Types of Thumpers

If you are a brewer and wonder what type of thumper to use, you need to understand different types of thumpers. The following are the three most common types of thumpers:

The Pot Still Thumper

The Pot Still thumper is a container placed between the pot still and the condenser. The thumper collects the distillate from the pot still and sends it to the condenser. This thumper type is simple to use and does not require any additional equipment.

Here are the steps for installing pot still thumper:

  1. Mount the thumper on a sturdy surface near the pot still.
  2. Connect the thumper to the pot still using a silicone hose.
  3. Connect the thumper to the condenser using another silicone hose.
  4. Affix a clamp to each hose connection.
  5. Ensure that the hoses are not kinked and are of the same diameter.
  6. Turn on the pot still and let it run for a few minutes to heat the thumper.
  7. Turn off the pot still and let it cool down.
  8. Repeat the process for the condenser.

Advantages of Still Thumper

  • It is simple to use and does not require any additional equipment.
  • It is less expensive than other types of thumpers.
  • It is easy to clean.

The Disadvantages of a Still Thumper

  • It can only be used with a pot still.
  • It can only be used for light spirits like vodka and gin.

Column Still Thumper

A column still is a piece of distilling equipment used to produce ethanol and other alcoholic beverages. The column still consists of a long, vertical tube that is heated from below. The vaporized alcohol rises up the column, where it is condensed and collected.

This type of thumper is also known as a continuous column still and is used to produce high-quality spirits such as whiskey, vodka, and gin. Distilleries that produce these spirits will often have several column stills in operation at once.

The column still was developed in the early 18th century and has been used in the production of liquor ever since. While there are many different types of stills, the column is considered the most efficient and reliable. It is also the most expensive to operate, so it is primarily found in larger distilleries.

Advantages of Column Still Thumper

  • Produces a high-quality product
  • More efficient than other types of stills
  • Reliable and durable


  • The thumper is expensive to operate
  • Column stills are large and require a lot of space

The Reflux Thumper

The reflux thumper is a more sophisticated thumper used in conjunction with a column still. It is a container filled with liquid and mounted above the still. The vaporized alcohol rises up into the thumper, where it is cooled and condensed.

This process causes the liquid in the thumper to become thicker and more viscous. The thumper helps to improve the quality of the final product by removing any impurities that may have been missed by the still.

A reflux thumper is widely used by commercial distilleries, as it produces a high-quality product with little to no impurities.


  • Produces a high-quality product with little to no impurities
  • Easy to use and set up
  • Improves the quality of the final product


  • It can be expensive to purchase
  • Requires a fair amount of space to set up

Where To Source For Thumpers

You should get a good brewing thumper for your home distilling system if you want quality spirits and brews. Thumpers are essential because the first few runs of spirit or brews produced are too raw for human consumption. The first brews also have a bitter taste, thus necessitating a thumper.

Here is how you can acquire a thumper:

Purchase One From a Local Vendor or Online

Find a thumper from an online vendor or buy from your local supplier. You should buy from a reputable vendor to ensure that you get the best quality thumper. Check out the reviews of the product and compare prices with other vendors.

The best place to buy a thumper is online, which gives you access to a wider selection of products. Buying online also allows you to compare prices easily and helps you find the best deals.

Make use of Your JunkYard

If you decide to make your own thumper. Start by looking for the components. An excellent place to look is in old car radiators made of solid brass or copper. The best place to look for one is at a junkyard where they sell used parts from old vehicles.

A suitable radiator will have many small tubes and a metal cap for the bottom of the tank. The cap is the most challenging part to find, and it’s very important that you get the right size.

What Are the Benefits of Using a Thumper?

The innovation of thumpers came with many benefits that brewers continue to enjoy today. Chief among those benefits is that thumpers help create a more consistent product. In particular, they help to produce beer with a more consistent flavor, mouthfeel, and carbonation.

Additionally, thumpers help reduce the amount of foam produced during the brewing process, leading to a less cloudy beer. Thumpers can also create a more efficient brewing process, which can help to reduce the amount of time it takes to produce a batch of beer.

Other benefits include:

  • Improved beer clarity
  • More consistent carbonation
  • Reduced foam production
  • Faster brewing process times

How Much Does a Thumper Cost?

Handy people can set up their thumper using locally available materials such as buckets, airlocks, PVC pipe, PVC fittings, screws, washers, and a drill. The total cost of locally a thumper ranges around $20. Thumpers come in various sizes, with the cost varying based on capacity, complexity, and the dealer.

When purchasing a thumper to brew your beers, the average price ranges from $12.89 to $2,650.00. These costs depend on the quality and design of the thumper you wish to purchase and the dealer you purchase it from.

The prices of thumpers depend on other factors like size and other specifications such as insulation. For example, two-gallon thumpers cost less than 10-gallon ones due to the amount of space taken up by the glass container or wine barrel compared to plastic containers.

How to Clean and Maintain a Thumper

Like any other tool, a thumper must be appropriately cleaned and maintained to ensure its optimal performance. It is essential to clean the inside of the thumper as well as the hoses and connectors that attach it to the brewing system.

To clean a thumper, use a soft brush or cloth to remove any sediment or debris that may have built up. Be sure to rinse the thumper with hot water and then dry it completely before reassembling the brewing system.

Keeping the seals around the inlet and outlet ports clean and free of debris is also important. If beer or other liquids are allowed to build upon the seals, it can cause them to become damaged and may eventually lead to a leak.

The following are some of the ways of maintaining a thumper:

  • Regularly clean the inside and outside of the thumper
  • Make sure the seals around the inlet and outlet ports are clean and free of debris
  • Replace any damaged seals immediately
  • Be sure to store a thumper when it is not in use properly
  • I should clean the gaskets regularly to prevent bacterial growth, especially when used in warm temperatures.
  • When heating the mash or wort, the pressure should be monitored to ensure that it does not exceed 20 psi. Pressure gauges can fail without warning, so it’s wise to follow safe practices for working with pressurized containers.

What Are Some Drawbacks of Using a Thumper?

A thumper can be a great addition to a home brewery. However, there are some drawbacks to consider before deciding to use one. For instance, when using a thumper, the alcohol produced is less potent than that which comes out of a pot still or column still.

Some thumpers are also not ideal for making high-proof liquors like vodka or rum, but they work great for whiskey! A thumper also requires additional equipment, including hoses, clamps, and plumbing fittings that may not be included with the still.

Since a thumper is open to the atmosphere, it can pick up bacteria, multiplying sugar content. Thus, it needs to be cleaned after every use. In addition, there is no way to tell when the thumper has reached its maximum possible alcohol content.

Other drawbacks of using a thumper include:

  • The cost of building or buying a thumper can be pretty high for home brewers who just want to make a small batch.
  • If the airlock gets clogged, there’s no way for carbon dioxide to escape so that it can blow the lid off the brew bucket.
  • Since the thumper only has one stage of fermentation, to get a very high alcohol level, one might have to add more sugar than in a two-stage fermentation process. That could lead to a beer that is too sweet.
  • If brewers don’t use proper sanitation techniques, they risk infection or contamination when using their thumpers.
  • It’s time-consuming and requires additional equipment that may not be available to everyone, especially the glass container). A thumper also takes up more space than just doing one fermentation process.
  • Brewers must monitor their thumpers constantly or risk having their beer spoil.

Frequently Asked Questions

Is It Necessary to Use a Thumper?

No, though using it will improve the first distillate. A good alternative is to run the still with a pot of water on top of the column. Thumpers help add alcohol to the brew by taking the vapors from the first distillation, re-distilling them, and giving the liquid a better taste.

Which Is More Important, the Mash or the Thumper?

It is a question that has been asked many times, and the answer is that it depends on the brewer’s preference. Some brewers believe that the mash is more important, while others feel that the thumper is more important.

The truth is that both are essential to the brewing process and play an important role in producing a high-quality batch of beer.

Is a Thumper Safe?

Yes, a thumper is a safe and effective way to improve beer quality. However, it is important to remember that a thumper should only be used by someone familiar with the brewing process and knows how to clean and maintain it properly.

What Happens if You Don’t Use a Thumper?

If you do not use a thumper, you will still be able to produce a batch of beer, though the quality may not be as good as it could be. Using a thumper helps to improve the first distillate, leading to a tastier and more consistent beer.


The thumper acts as an extra chamber in which I can brew beer. Besides filtering impurities, the thumper also adds extra flavor to beer. Because of its unique design, I get more heat exchange than a regular pot, resulting in higher temperatures and better-tasting beer!
