Making a mash tun out of a cooler is a great way to make all-grain homebrew without investing in a lot of expensive homebrewing equipment. To make a mash tun out of a cooler, you will first need to purchase a cooler, such as an Igloo cooler, that is large enough to hold the amount of wort (the liquid obtained from mashing grains) that you are intending to make.
You also need to purchase a false bottom for the cooler, which is a perforated plate that fits into the bottom of the cooler and allows the liquid to pass through it, but prevents the grains from passing.
You will also need a hose with clamps to attach the false bottom to the outlet of the cooler.
Next, you will need to install the false bottom onto the cooler. Start by removing the drain plug from the cooler, then insert the false bottom into the bottom of the cooler, making sure it is centered.
Secure the false bottom in place with the screws provided. Then attach the hose to the outlet at the bottom of the cooler, and secure it with the clamps.
Once the false bottom is installed, you are ready to add your grains to the mash. Begin by heating the water to your desired temperature, and then pour the water into the cooler. Once filled, stir the grains into the hot water and ensure that the mash is mixed properly.
Once the mash is complete, you are ready to vorlauf (recirculate) the mash and begin sparging (rinsing out the sugar from the grains). This is the process of transferring the sugar-rich wort from the grains into a separate vessel for boiling.
To do this, use a rousing tool to pull the wort from the mash tun, and then pass it back into the mash tun through a strainer. This will help to separate the wort from the grains, as the wort passes through the false bottom and out the hose.
As you vorlauf, continue to stir the mash to ensure that all the grains are completely mixed and evenly rinsed.
Finally, it is time to sparge the mash. Begin by pouring hot water over the grains, allowing the water to pass through the false bottom, and collecting the wort at the hose. This process should be repeated several times until all the sugar-rich wort has been extracted from the grains.
After all the Wort has been transferred, your mash tun is ready to be used.
Making a mash tun out of a cooler is a relatively easy and cost-effective way to brew all-grain beers without having to invest in a lot of equipment. By following the steps listed above, you can easily and quickly create your own mash tun and begin brewing delicious beer right in your own home.
How do you convert Igloo cooler to mash tun?
The process of converting an Igloo cooler into a mash tun is relatively straightforward, but it does involve some specific pieces of equipment and steps. To begin, you will need to purchase a false bottom and a bulkhead fitting kit.
The false bottom will allow the grains of malt to sit a few inches above the actual bottom of the cooler, thus allowing the wort to pass through to the spigot. The bulkhead fitting kit will include the necessary valves, fittings, and hoses to connect your mash tun to your wort chiller.
Additionally, you will need to purchase a thermometer and a mash paddle.
Once all of the necessary pieces of equipment are acquired, it’s time to begin the conversion. Start by drilling a hole in the side of the cooler near the bottom. This is where the bulkhead fitting will be installed.
Once the hole is cut, fit the bulkhead fitting into place, ensuring a tight seal. After the bulkhead is in place, install the false bottom. This will sit atop the cooling for it’s functioning. Finally, connect the appropriate hoses and valves from your wort chiller to the bulkhead fitting.
Be sure to use appropriate fittings and techniques to ensure the mash tun is properly sealed and operating safely.
Now that everything is set up, you’re ready to begin mashing. Place your desired volume of grains into the mash tun and begin heating to the desired temperature. With the thermometer inserted, you can easily monitor the temperature of the mash.
As it heats, you can use the mash paddle to stir and aerate the wort. When the mash is finished, it’s time to begin recirculation and sparging. Connect a hose to the output valve of the mash tun and the input valve of your wort chiller, allowing the cooled wort to run into the collecting vessel of your choice.
Finally, disconnect the hoses, remove the false bottom and remove it for cleaning. Your Igloo cooler is now a fully functional mash tun!.
How do you make a homemade mash tun?
Making a homemade mash tun can be relatively easy and relatively inexpensive. You will need a cooler (typically at least a 10 gallon cooler to have enough room in the mash tun for a five or six gallon batch of beer), a drill, a stainless steel mesh bag (or false bottom), a stainless steel ball valve, a rubber or silicone gasket, and some high-temperature silicone sealant.
First, decide on a location for your mash tun and pre-drill the cooler in several places to attach the stainless steel ball valve. Insert the ball valve through pre-drilled holes and attach it using the rubber/silicone gasket.
Once the ball valve is in place, coat the interior of the cooler at the area where the ball valve attaches with the high-temperature silicone sealant for extra protection.
Next, insert the stainless steel mesh bag or false bottom into your mash tun. This will act as a filter to keep the grains from entering the wort. The false bottom will usually come with instructions on how to assemble it, but if you’re using a mesh bag, you’ll need to attach it with a bungee cord or some other type of tie.
Finally, you can test your mash tun by adding some grain and water. Once you begin the mash, regularly check the temperature to ensure that it is mashing at the ideal temperature.
Making your own mash tun can be a great way to save money and make excellent beer. Just make sure that you carefully follow all the steps to ensure a successful mash tun.
Is it safe to use a cooler mash tun?
Yes, it is safe to use a cooler mash tun if it is properly assembled. Inspect the cooler for any visible damage or signs of wear and tear. If you find any cracks or signs of wear and tear, replace the cooler with a new one.
Second, invest in a high- quality false bottom and spigot to prevent the grain from clogging the drain. Third, make sure that the cooler is sealed tightly to prevent any possible leaks. Finally, before each use, completely sanitize and rinse the cooler to prevent any bacterial contamination.
After following these steps, a cooler mash tun is safe and ready to use.
What is the difference between a mash tun and Lauter tun?
The main difference between a mash tun and a lauter tun is their purpose. A mash tun is used to make the mash, which is a combination of grains, water, and other ingredients that bring specific flavors and aromas to the beer.
The mash is usually heated, usually to about 150-158°F (66-70°C), and is then left to steep for an hour or more.
In contrast, a lauter tun is used to separate the grain from the liquid wort. This is done by recirculating the wort through the grain bed, which allows the starches from the grains to be converted into sugars.
The husks of the grains act as a filter bed, allowing clearer wort to flow out of the bottom of the lauter tun. The used grains are then removed, and the clarified liquid is passed on to the brew kettle.
The lauter tun process is more efficient than mashing, and can produce better results in terms of clarity and taste.
How does a false bottom mash tun work?
A false bottom mash tun is an essential piece of equipment for the homebrewing process. It is designed to separate the liquid ingredients from the solid substances. This ensures that the wort produced is clear and ready for further fermentation.
The false bottom has a perforated, stainless steel plate or disk with small holes that allow the hot liquid to pass through while keeping the solids in the mash. The false bottom also helps the wort drain evenly, ensuring the full extraction of sugars and other desirable flavors from the grain.
The false bottom mash tun is typically made of a stainless steel perforated plate that rests on a frame and stand. This plate is sitting above the mash and is about an inch from the bottom of the vessel.
The grain remains at the bottom of the tun and is contained using the false bottom, allowing the hot liquid wort to drain through the perforations.
The false bottom also provides an additional benefit – as the mash becomes cooler and starts to firm up, the false bottom will gently move up and down, preventing the grain from getting stuck to the bottom and forming a crust, which can be difficult to remove.
This ensures the brew is as efficient as possible, and that no grain is wasted.
Ultimately, a false bottom mash tun is a great piece of equipment for homebrewers, allowing them to ensure the clarity of their wort and ensure the full extraction of sugars, enzymes, and other flavors.
What is a lauter tun?
A lauter tun is a type of brewing tank used in the brewing process to separate the solids from the wort. It is an important part of the all-grain brewing process, where the grains need to be steeped in hot water to extract the fermentable sugars.
To do this, the grains are placed in the lauter tun. Hot water is then added to the tank and the grain particles are stirred and allowed to settle. After this, the wort is drawn off the bottom of the tank while the husks and other solids remain behind.
The lauter tun acts like a filter, allowing the liquid to pass through while the solids remain. This process can be done manually or through the use of a sparging device to help circulate the liquid and promote faster filtration.
The act of drawing off the wort is known as lautering and a lauter tun is a critical tool in the process.
What is sparging water?
Sparging water is a process used in the brewing of beer and alcoholic beverages. It involves the use of a sparge arm, a tube, and a pump to aerate the sugar-filled liquid used to create the beer. This process is what gives beer its full, deep flavor and aroma.
The sparge arm helps the brewer to evenly disperse the wort, the sugar-filled liquid, over the grains of malt. The wort is heated and mixed with oxygen which helps to break down the starches in the grains and release the sugars.
The liquid is then pumped through the grain bed, with the help of the sparge arm, and this is known as sparging. As the liquid is pumped, it dissolves the sugars into solution, allowing them to be used by the yeast during fermentation.
The sparge arm also helps to create a consistent liquid flow, allowing the brewer to control the temperature of the wort and the rate of sparging. Sparging is an important step in the brewing process and is what helps to create the great flavor and aroma found in beers and other alcoholic beverages.
What is a BrewZilla?
A BrewZilla is an all-in-one home brewing system designed to make brewing beer, mead, cider, and even root beer at home easy and efficient.

What is a false bottom in brewing?
A false bottom in brewing is a type of component that is used in a mash tun or lauter tun to separate the solid particles from the liquid. It is generally made from a perforated metal plate, a piece of stainless steel mesh, or another type of filter material.
Its design allows liquid to flow through it while preventing larger particles from passing through. A false bottom creates a barrier between the solid particles of the mash and the liquid, which helps to create a clearer wort and improve the efficiency of a batch.
In addition, many brewers believe that a false bottom creates better head retention in the beer. False bottoms are also easier to clean than other types of filters, making them a popular choice among home brewers.
How do you use a false bottom?
A false bottom is a layer of material that is placed underneath a larger layer of material, often in the bottom of a container, to conceal a hidden space or compartment. False bottoms can be used in a wide variety of applications and can be made from a variety of different materials.
To use a false bottom, start by determining the purpose for the false bottom. This will help in deciding what type of material and size of false bottom to use. Generally, false bottoms are designed to fit inside containers or other projects, so be sure to measure the dimensions of the container or project before selecting a false bottom.
Once the false bottom is selected, it will usually need to be cut to size. If metal is being used for the false bottom, metal shears or metal snips should be used to avoid warping or other damage. Take measurements before beginning to cut the false bottom to make sure it will fit correctly when finished.
It may be helpful to mark where to cut with a piece of tape.
When the false bottom has been cut to size, it is ready to be placed in the container or project. Before doing so, make sure that the container is clean and clear of any debris. Make sure the area where the false bottom will rest is flat and even.
If necessary, use adhesive or other fasteners to help secure the false bottom in place. Make sure the fasteners fit securely around the outer edge of the false bottom to ensure that it is secure.
Once the false bottom is in place, any internal contents of the container can be placed or stored in the hidden space beneath the false bottom. This could be items like money, jewelry, or other small items that you wish to keep hidden for security or other reasons.
Does a mash tun need to be sanitized?
Yes, it is important to sanitize a mash tun before and after use. Sanitizing your mash tun prevents bacteria, mold and wild yeast from contaminating your brew and ruining it. When sanitizing your mash tun, it is important to use a sanitizer specifically designed for brewing, as other sanitizing products can be harmful if used for brewing.
It is also important to thoroughly rinse off the sanitizer afterwards to ensure it does not affect the flavor of the brew. Depending on how your mash tun is used, it should be sanitized after every use.
Additionally, it is beneficial to sanitize the mash tun before and after making large batches of beer, when changing grains and after leaving the mash tun idle for a prolonged period. Following these sanitizing guidelines can help to ensure that your brew is free of contaminants and tastes great each time.
Do you rinse after sanitizing?
Yes, it is important to rinse after sanitizing. Sanitizing solutions use chemicals that can leave behind residues if they are not thoroughly rinsed off with clean water. Additionally, sanitizers are made to kill bacteria and viruses, however they will not always remove them completely.
Allowing the residue to sit on a surface, such as dishes, can cause bacteria and viruses to start growing again. Rinsing the surface with clean water will help remove any remaining residue and any particles still on the surface, thus preventing the growth of any microbes.
Can I use bleach to sanitize brewing equipment?
Yes, you can use bleach to sanitize brewing equipment. When sanitizing the brewing equipment, mix four gallons of water with one ounce of bleach. Then, use a plastic brush to scrub all of the surfaces you want to sanitize.
After scrubbing all surfaces, let the solution sit for no more than 10 minutes, then rinse all surfaces with cold water and let them air dry. Make sure to use gloves when handling the bleach solution, and never mix bleach with other cleaning products.
Finally, it is important to note that bleach should only be used for occasional sanitizing – not as a regular cleaning agent.
Does it matter how much water you mash with?
Yes, it does matter how much water you mash with. The amount of water used in your mash, otherwise known as the “mash ratio”, is a key factor in producing a quality beer. The mash ratio is important in determining the sugar extraction efficiency of your malt.
The more water in the mash, the more efficiently sugars will be extracted from the malt. If too little water is used during the mash, the efficiency will be low and you won’t get the desired malt character out of your beer.
If too much water is used, the beer may have too strong a flavor and mouthfeel. The desired mash ratio is usually somewhere in the range of 1-2 quarts of water per pound of grain. Many experienced brewers will adjust the water/grain ratio based on the type of grain they’re using, as different grains have different characteristics and require different amounts of water to extract the necessary sugars.
It is important to find the right balance when mashing.
