Making your own Herms brewing system requires some effort and knowledge in plumbing, electrical wiring and motors, as well as a fair bit of work. Here is a basic overview of the steps involved:
1. Purchase and assemble the components. You need a hot liquor tank, a mash tun with a false bottom, a sparge arm, a counter flow heat exchanger, an immersion chiller, pumps (big enough to cycle the entire volume of your system, in our case that’s 12 gallons), fittings, hose, wort chillers, kettles and a burners.
2. Get the plumbing and pumps ready. You will have to decide the best way to route plumbing and attach pumps, as well as decide on the appropriate intake and output sizes.
3. Give your mash tun a false bottom. A false bottom allows the grains to be steeped and also allows for recirculation of the wort back into the mash.
4. Install the control panel on the hot liquor tank. This panel will allow you to control the temperature of the water while mashing, as well as keeping the hot water warm while sparging.
5. Wire the system together. You will need to connect all the pieces of the system to a power source and run wiring throughout the system.
6. Setup the malt pipe. A malt pipe will allow you to add your grains to the mash tun.
7. Connect the kettles and hoses. You will need to route the appropriate hoses from your pumps to the hot liquor tank, mash tun, boil kettle, and output line for racking.
8. Setup and connect your burners. You will need to decide on the appropriate size and adjust the intensity.
9. Connect the temperature probes and fittings. Connect the temperature probe and heater to the false bottom of the mash tun, as well as attach the Immersion Chiller to the boil kettle.
10. Test the system and enjoy brewing. After you have connected everything together, it’s time to test the system and make sure everything is in working order. If everything looks good, it’s time to enjoy the process of brewing.
Are Herms better than RIMS?
It depends on what your preferences are. Herms systems consist of a stainless-steel brew kettle with an attached recirculating mash tun, making it ideal for all-grain brewing. If you are doing partial-grain and extract brewing, a HERMS system will still work, although you won’t get the same consistency as you would from a RIMS system.
In addition, a HERMS system is a good choice if your goal is to produce good lagers, as the heat exchanger in the mash tun allows for cooler temperatures, which can help maintain a constant temperature when mashing.
On the other hand, a RIMS system is great for accurate, consistent temperature control. RIMS stands for Recirculating Infusion Mash System and consists of a recirculating pump and a heat exchanger. This allows the brewer to mash at a specific temperature, which requires less supervision as compared to a HERMS system.
Ultimately, the choice between a HERMS and RIMS system comes down to personal preference. Both systems have their advantages and disadvantages, and choosing one over the other really depends on what kind of brewing you intend to do.
What does Herms mean in brewing?
Herms (or “Heat Exchange Recirculating Mash System”) is a brewing system that combines the benefits of recirculation and temperature-controlled hot liquor tank (HLT) to create a stable, temperature-controlled mash environment.
Essentially, the Herms system consists of a glycol-chilled coil placed in a hot liquor tank, connected to a pump, and then connected via hoses to a mash vessel. During the mash, the hot liquor tank maintains a stable temperature by evenly recirculating the liquid.
Then the liquid is circulated through the coil in the hot liquor tank, which is connected to a glycol-chilled system. This chilled liquid is then pumped through a stainless-steel coil that is wrapped around the outside of the mash vessel, allowing for very precise temperature control of the mash by maintaining a constant temperature throughout.
The advantages of using a Herms system are numerous. By using a recirculating loop, the mash can be held at a constant temperature, eliminating the need for frequent stirring, ensuring consistent mash temperatures, and reducing the need for manual temperature control.
Additionally, the ability to precisely control mash temperatures enables brewers to adjust their recipes, allowing them to better dial in the desired flavor profiles. Overall, the Herms brewing system is an excellent tool for the modern brewer allowing for a more consistent and reliable brewing process.
How do I build a recirculating mash?
Building a recirculating mash is a great way to increase the efficiency of your homebrewing setup. The main components of a recirculating mash system are a mash tun, a false bottom, a recirculating pump, and a chiller.
The first step is to build your mash tun. This is where you will add the malts and hot water to make the mash. You can use a regular brew kettle or purchase a dedicated mash tun. To make a dedicated mash tun, you’ll need a tall enough vessel to fit your false bottom and make sure it is made out of a material that won’t corrode.
The next step is to install a false bottom. This is a perforated plate that sits in the bottom of the mash tun. It acts as a filtration system and helps ensure that the grains don’t clog up the pump.
You’ll want to make sure you get one that is designed specifically for your mash tun.
Once you’ve installed the false bottom, you’ll need a recirculating pump. This is typically installed on the side of the mash tun and used to move the wort through the false bottom filter. You’ll also need to get a hose that fits the recirculating pump, which allows you to divert the wort to a chiller.
The last piece of equipment you’ll need is a chiller, which is used to cool the wort after it is pumped out of the mash tun. But the most common are immersion and counterflow chillers. Immersion chillers are the most basic and can be used for small batches.
Counterflow chillers are more efficient, but can be more expensive.
Once you have all of these pieces of equipment, you are ready to start the mashing process. You’ll want to fill the mash tun with your malts, then add hot water to create the mash. Once the mash is created, use the recirculating pump and hose to move the wort through the false bottom filter and into the chiller.
Once the wort has been chilled, you are ready to move on to the next step in the brewing process.
Should you recirculate during mash out?
Yes, you should recirculate during mash out. Recirculation during mashing helps ensure good conversion of starches to sugars as well as improve the clarity of the wort, which helps in separating the grain bed from the liquid.
Recirculation during mash out has the benefit of rinsing and washing out any residual sugar or starches that may be left in the mash tun and improve flavor and aroma in the wort. It will also help control the temperature in the mash by maintaining a consistent temperature.
This helps reduce the chance of a sour mash and helps to create a smoother beer. Additionally, recirculating during mash out helps to keep the mash in suspension when it is drained and sparged so it is less likely to stick to and coat the walls of the tun and burn.
This allows for a smooth, even lauter and can result in a better tasting beer.
Is recirculation necessary for BIAB?
Yes, recirculation is necessary for BIAB (Brew In A Bag) to ensure that all of the wort is mixed together and evenly heated. This also helps draw out flavor and aroma compounds, as well as aid in hydration of starches.
During recirculation, the wort should pass through the grain bag, allowing the grains to be mixed in and ensuring that the mash remains in good contact with the liquid. Additionally, recirculation can help to clarify the wort, as the grains will act as a filter and catch any proteins or undesired particles.
This will result in a much clearer finished product. Recirculation also helps ensure an even temperature throughout the mash, as any cold spots in the wort will be mixed in, and any hot spots will be cooled off.
Overall, recirculation is necessary for BIAB in order to ensure that the mash is mixed together, clarified, and heated evenly. This will lead to a much better product overall.
What is sparging water?
In order to extract the most possible sugar from the grain during brewing, brewers utilize a process called sparging. Sparging is simply rinsing the grain with hot water in order to wash away the residual sugar that is left behind after the mashing process.
There are two different types of sparging: fly sparging and batch sparging.
Fly sparging is the most common type of sparging and is typically used by commercial brewers. Fly sparging is a continuous process where wort is slowly drawn off the top of the mash tun while hot water is slowly added to the mash tun from the bottom.
This process is repeated until the desired pre-boil volume is achieved.
Batch sparging is a simpler process that can be used by both commercial and home brewers. Batch sparging is done by draining all of the wort from the mash tun and then adding an equal amount of hot water to the mash tun and stirring.
This process is repeated once or twice until the desired pre-boil volume is achieved.
How do you use Blichmann Autosparge?
Blichmann Autosparge is a device which automatically controls the flow rate of water in your mash tun. It helps keep the water to grain ratio consistent for a consistent mash throughout the process. To use the Blichmann Autosparge properly, begin by setting up your mash tun and connecting the Autosparge to your water source.
Then attach the Autosparge’s stainless steel tubing to the bottom of your mash tun. Next, attach the quick disconnect to the Autosparge and fill the Autosparge with water from your water source. To begin sparging, attach the Autosparge to the hot water supply and open the cock valve on the Autosparge or open the valve on the water source.
The Autosparge will start to automatically pump the mash. Once you hear a slight hissing noise, you know that it’s sparging water at the desired rate. Finally, monitor and adjust the sparge rate as necessary while maintaining your mash temperature.
When finished, turn off the power and disconnect the Autosparge from the water source.
What is the difference between Herms and RIMS?
The biggest difference between Herms and RIMS is that Herms uses an immersion coil in the wort to heat it, while RIMS uses a heating element in the recirculating Mash to heat it. The first is that, because the heating element in a RIMS is in constant contact with the wort, it can burn the wort if the temperature gets too high.
The second is that, because the heating element in a RIMS is in constant contact with the wort, it can extract more bitterness from the hops. The third is that, because the heating element in a RIMS is in constant contact with the wort, it can caramelize the sugars in the wort, giving the beer a more caramelly flavor.
The fourth is that, because the heating element in a RIMS is in constant contact with the wort, it can over-extract the proteins in the wort, giving the beer a haze. The fifth is that, because the heating element in a RIMS is in constant contact with the wort, it can over-extract the tannins in the grain, giving the beer a astringent flavor.
The sixth is that, because the heating element in a RIMS is in constant contact with the wort, it can over-extract the color from the grain, giving the beer a darker color. The seventh is that, because the heating element in a RIMS is in constant contact with the wort, it can over-extract the flavor from the grain, giving the beer a more grainy flavor.
The eighth is that, because the heating element in a RIMS is in constant contact with the wort, it can over-extract the oils from the hops, giving the beer a more resinous flavor. The ninth is that, because the heating element in a RIMS is in constant contact with the wort, it can over-extract the bitterness from the hops, giving the beer a more bitter flavor.
The tenth is that, because the heating element in a RIMS is in constant contact with the wort, it can scorch the wort, giving the beer a smoky flavor. The eleventh is that, because the heating element in a RIMS is in constant contact with the wort, it can over-heat the wort, causing a loss of fermentables and leading to a thinner body.
The twelfth is that, because the heating element in a RIMS is in constant contact with the wort, it can over-heat the wort, causing off-flavors. The thirteenth is that, because the heating element in a RIMS is in constant contact with the wort, it can over-heat the wort, causing the beer to have a lower alcohol content.
The fourteenth is that, because the heating element in a RIMS is in constant contact with the wort, it can over-heat the wort, causing the beer to be morestale. The fifteenth is that, because the heating element in a RIMS is in constant contact with the wort, it can over-heat the wort, causing the beer to be more oxidized.
Finally, the sixteenth is that, because the heating element in a RIMS is in constant contact with the wort, it can over-heat the wort, leading to a bacterial infection.
How does a Herms system work?
A Herms system works by circulating hot wort from the brew kettle, through a heat exchanger (or other temperature control device) heated by a separate hot liquor tank, and back into the kettle. The wort is circulated for as long as necessary to maintain a stable temperature for the mash, which allows for a more efficient and thorough conversion of starch to fermentable sugars by the enzymes in the grains.
Once the mash has been converted and the hot wort has been collected, it is recirculated through the Herms system again, this time through the wort chiller to bring the liquid down to a temperature suitable for the yeast.
At this point, the wort is ready to be transferred to a fermentation vessel, where the yeast can then begin the fermentation process.
The main benefit of using a Herms system is that it provides complete control over the mash and wort temperatures, allowing the brewer to adjust temperatures as needed to reach their desired outcome.
This in turn leads to increased efficiency in the mash, better tasting beer, and a smoother brewing process overall.
What is a Herms coil?
A Herms coil is a type of heat exchanger that is used in brewing systems. It is a specialized coil made from stainless steel or some other material that has a cooling or heating medium running through its internal passages.
A Herms coil is designed to provide an efficient and consistent temperature control for mashing and sparging, both of which are crucial to the beer brewing process. The coil helps to keep wort at a steady temperature which allows the enzymes to break down the sugars more efficiently, ensuring more complete conversion of fermentable sugars and a better flavor profile in the beer.
The Herms coil also helps to keep any undesirable proteins and other unwanted components from becoming part of the finished beer as well. By circulating hot and cold water through the coil, the coil helps to maintain an optimal temperature range.
Additionally, a Herms coil helps to keep heat evenly distributed throughout the wort, reducing the risk of hotspots and potential off-flavors that could harm the beer.
How does a 3 vessel brewhouse work?
A 3 vessel brewhouse is a brewing system that typically consists of three separate vessels to handle different steps of the brewing process. This system is typically set up to provide a more efficient and automated process to produce beer.
The first vessel, or “hot liquor tank”, holds hot water that is heated to the desired temperature that is necessary for the brewing process. This hot water is then combined with the malt, or grain, to create the “mash” which is the first step in the production of beer.
This mash is stirred and held at a consistent temperature for an extended period of time, sometimes up to 2 hours, to activate enzymes in the grain allowing the brewer to convert starches into fermentable sugars.
The second vessel, or “mash tun”, is where the converted mash is transferred. Here the spent grain is separated from the wort, or liquid portion of the mash. Once the wort is separated, it is moved to the third vessel, which is referred to as the “boil kettle”.
In the boil kettle, hops and other additions are added to the wort and boiled for 60 minutes to extract the oils and flavors from the hops.
Lastly, the boiled wort is transferred to the fermentation vessel where the yeast is added and allowed to ferment over the course of a few weeks. Once the primary fermentation process is complete, the beer is moved to a secondary fermenter, or conditioning tank, and can be held there until it is ready to be transferred to a keg or bottle.
A 3 vessel brewhouse is an effective way to quickly and efficiently produce beer at scale. Its efficient design is what makes it the preferred method of brewing for many craft breweries.

What is a decoction mash?
A decoction mash is a type of mashing process used in the brewing of beer. It involves the periodic heating and cooling of portions of the grist, typically around 50-70% of the total, in a decoction vessel.
This separation of the grain is meant to enhance the enzymatic conversion of starches to complex sugars, resulting in a fuller body and greater depth of malt character in the finished beer.
During a decoction mash, a portion of the grist is heated to boiling and then separated from the rest of the mash in a decoction vessel. This mash is often boiled for an extended period of time with the intent to break down proteins and complex starches that result in a fuller, maltier finished beer.
It’s essentially a way of taking advantage of the varying temperatures that form the various steps of traditional mashing. After the heating, the decocted mash is then cooled and returned to the original mash for the next step in the mashing process.
This can be repeated multiple times across different temperature ranges as required by the malt used in the recipe.
Decoction mashing has become less commonplace in recent decades, due in part to the availability of more advanced malts that require less conversions and can easily be handled in a single-step infusion mash.
However, decoction mashing is still regularly used in traditional brewery cultures that value the body and flavor that the process can impart to a beer. Additionally, there is a certain level of artistry to decoction mashing that has allowed it to maintain a dedicated following among homebrewers.
Which is better rims or Herms?
This is purely a matter of personal preference. Both rims and Herms are good quality products, and can provide users with the opportunity to brew excellent-tasting coffee.
Rims brewers offer a quick and relatively inexpensive way for people to make their own barista-level coffee at home. Rims systems are ideal for those with a limited budget, or those who need a great-tasting cup of coffee within minutes.
Rims systems are easy to use, and generally have fewer components than Herms systems.
Herms brewers provide a more comprehensive, comprehensive coffee-making experience than rims systems. They allow the user to fine-tune their brewing parameters, and have more features like PID temperature control, pre-infusion, and AICC calibration.
They tend to be more expensive than rims brewers, but they provide more control over the brewing process and are preferred by people who want to make a more advanced cup of coffee.
In the end, whether you choose a rim or Herms system is up to you. Consider your specific needs and budget to decide which system is best for you.
How long should Herms coil be?
The length of the coil for Herms will depend upon the application. In most cases, the best practice is to keep the length of the coil at a minimum. Generally, this will be 12-18 inches. In some applications, the Herms coil should be longer, such as when dealing with larger volumes of liquid and/or extended process times.
In this instance, a length greater than 18 inches may be necessary. Ultimately, the coil should always be long enough to meet the specific needs of the application.
