Beer is not created by chance. Each stage – from mashing, through fermentation, to maturation – requires precision, repeatability and the right conditions. That is why brewing installations are more than just pipes, valves and tanks. They are the heart of the entire brewery – and how they are designed and constructed has a direct impact on the taste of the finished beer.
Unlike many other systems in the food industry, every detail counts here. Inaccurate welding, poorly selected material or a connector that is difficult to clean can result in something you definitely do not want ending up in the beer – from bacteria to unwanted aromas. And then the whole process has to be started all over again.
A well-designed installation is one that not only works, but also supports the quality of beer production. It must be hygienic, easy to clean, resistant to temperatures and pressure. And how is it made? It is best to use methods such as orbital welding or TIG welding, which guarantee tightness and smoothness inside the pipelines and brewing tanks.
In this article, we will show you what really affects the quality of brewery installations and how to approach the subject so that your beer can mature peacefully – without surprises, downtime and corrections.
Key areas of the beer production process
Beer does not make itself. Every brewer knows that a well-planned and organized beer production process stands behind good taste. For everything to go smoothly, each zone in the brewery – from mashing to maturation – must be supported by properly designed brewing installations.
Below is a short reminder of what happens at each stage and why the technical quality of workmanship really matters.
Mashing – this is where it all starts
The malt is mixed with water and at the right temperature releases sugars, which will later turn into alcohol. If something goes wrong – for example, the temperature in the tank is “jumping” – the entire brewing process can go wrong. That is why precise control and good tank insulation are so important here.
Boiling – the fight for sterility
After filtration, the wort goes into the brewing kettle. Boiling with hops is the moment when the beer’s character is given – but it is also the first point of microbiological control. Any oversight in the installation, a leak, a bad weld – and you can say goodbye to a clean batch.
Cooling – every second counts here
Before the wort goes to the fermenters, it must be cooled – quickly and effectively. The longer it takes, the greater the risk of infections. At this point, the brewing installations must operate efficiently, and the entire cooling system must be tight, well thought out and made with precision down to the weld.
Fermentation – no room for error
In the fermentation tanks, the yeast does its job. But only when they have the right conditions: cleanliness, the right temperature and no contact with oxygen. The tank must be tight, easy to clean and resistant to pressure changes – and this means one thing: the quality of workmanship really counts here.
Maturation – beer matures in peace
This is the time when beer “comes to maturity”, clarifies and takes on its final character. The beer tank in this area should maintain the temperature and prevent any contamination. This is the last stage before bottling – it is important that everything is buttoned up.
Fermentation tank vs. maturation tank – what are the differences and what should you watch out for?
If you are just getting into brewing beer on a larger scale, it is easy to think that every beer tank looks similar and does the same thing. However – a fermentation tank and a maturation tank are two completely different worlds, and each of them has its own specific tasks and requirements.
Fermentation tank – where beer comes to life
This is where the actual beer production begins – the yeast gets to work and converts sugars into alcohol. In practice, this means that the tank must:
withstand the increasing pressure,
be 100% airtight (oxygen is enemy number one at this point),
have the ability to be precisely cooled,
and allow for easy cleaning, because a lot of sediment remains after fermentation.
It often has a conical bottom – this makes it easier to get rid of yeast and take samples.
A maturing tank – here the beer matures in peace
After fermentation, the beer must “rest”. It gains clarity, taste and aroma. This stage is calmer, but no less important. The maturing tank:
no longer has to withstand large pressure surges, but it still has to be solid,
should maintain a stable low temperature,
and – crucially – be easy to clean and resistant to dirt build-up.
There is no room for corrections here. If something goes wrong, the entire batch may not be suitable for bottling.
5 Mistakes That Are Easy to Make When Choosing Brewing Tanks
Is a tank a tank? Not necessarily. In theory, everything may be fine, but in practice – the beer doesn’t come out right or something has to be corrected every day. Choosing brewing tanks is one of those moments when not only the price matters, but above all, thinking the subject through from A to Z. Here are the most common mistakes that we see brewers make – especially those who develop on their own:
1. All tanks “on one shoe”
This is probably the most common mistake. Fermentation and lagering are two completely different stages that require different solutions. A fermentation tank should have, among other things, a conical bottom, a cooling system, valves for taking samples and a yeast drain. In turn, a lagering tank must, above all, maintain a low temperature and be as hygienic as possible. One type of tank for everything? It may be convenient, but in the long run – it is a costly mistake.
2. “The interior? Nobody looks there anyway”
Yes, they do – wort, yeast, detergents. If the inner surface of the tank is not smooth enough (read: Ra ≤ 0.8 µm), CIP cleaning will not be effective. And this is a direct path to problems with the quality of beer production.
3. Welds “by eye”
It looks good from the outside, but what counts is what’s inside. The quality of welding is the foundation of safety and hygiene. If the welds are imprecise, uneven, porous – the tank will be a breeding ground for bacteria. It’s really not worth saving here. It’s better to focus on high-quality welding, preferably with documentation and tests.
4. Poor cooling – and then saving fermentation
In the summer, everything happens faster – also in the tank. If you don’t have an efficient cooling jacket, the beer may ferment too quickly or unevenly. This affects the taste, aroma and stability of the product. When buying a tank, be sure to ask about the heat exchange surface – it’s not a detail.
5. No one thought about servicing
Sometimes the tank looks great, but then… you can’t replace the valve, CIP doesn’t reach all the nooks and crannies, and some of the equipment has to be imported from the end of the world. But servicing beer installations should be simple, fast and accessible – especially when the brewery is growing and every hour of downtime hurts.
Welding quality control – how to protect beer from infection?
Many brewers focus on what you can see in the glass: aroma, foam, color. But before the beer gets into the mug, it has to go all the way through the installation. And it is there – in the pipes, tanks, valves – that a problem that is easy to forget about can lurk: welds.
If the quality of welding fails, even the best raw material will not save the batch. A porous weld, a micro-leak or a poorly polished joint is enough for bacteria to have ideal conditions for growth. And that means one thing: infection, the consequences of which can be painful – both financially and in terms of image.
What does good control look like?
At Deffor, we are clear: welding is not just about joining metal – it is the foundation of hygiene throughout the entire process. That is why every installation we perform undergoes a thorough quality control of the welds:
First we look – literally. Visual weld inspection (VT) allows you to catch imperfections that are visible to the naked eye.
Then we check deeper – penetrant testing (PT) reveals microscopic defects that could become a source of infection.
Finally, we document – each weld made using the TIG method can be confirmed with a protocol, thanks to which you have black and white that everything is fine.
Why all this? Because welding in the food industry, especially in brewing, is more than just a technique. Here, precision, smoothness, lack of pores count – in a word: the certainty that nothing will spoil the taste of your beer.
Beer installation service – how to avoid a costly surprise
In a brewery, every day is a fight for taste, quality and repeatability. But even the best-designed brewing installation will not operate flawlessly for years if no one takes care of it. After all, service does not have to mean a major renovation – sometimes a plan and regularity are enough to sleep peacefully.
Inspections are not a whim
We sometimes hear: “The installation works, so why touch it?”. Exactly – as long as it works, it’s great. But when the tank starts leaking, the valve jams, and the weld gives way – the costs, downtime and (worse) the possible loss of the entire batch begin. That’s why it’s better to plan a simple but specific plan for beer installation service before something happens.
What is worth having under control?
regular technical inspections – so that you are not surprised by a minor failure in the middle of important fermentation.
inspection of welds – after all, they are the heart of the installation. And a small leak can mess up the taste a lot.
cleaning and reviewing CIP systems – because even the best cleaning systems become out of calibration over time.
modernizations – if you are planning new beers, changes to the line or expansion of the brewery – it is worth checking in advance whether the current installation will handle it.
And if something needs to be improved?
It is not a drama. Sometimes it is enough to replace a section of the pipeline, a valve or equip the tank with new sensors. Such minor modernizations of beer installations really make a difference – both in the quality of work and in the comfort of everyday brewing.
Restaurant brewery installation – from idea to first brewing
Imagine that you have your own restaurant. Guests know you, the cuisine is good, and the atmosphere of the place does its job. But you want to go a step further – serve beer brewed on site. Fresh, fragrant with hops, of your own making. Sounds like a dream? For us – everyday life, because we help to implement such brewery installations.
Stage 1: From vision to project
In this (made up, but very realistic) example, the owner of a small premises in a large city decided to open a restaurant brewery – one with a visible brewhouse, a few taps and the option of development in the future. He contacted us not only to buy equipment, but to do it well – wisely, with a plan, and without surprises at the start.
We would start with a brewery installation project, adapted to a small space and high sanitary requirements. We would plan:
a brewhouse, tanks and pipeline layout with future development in mind,
full cleaning automation (CIP),
fermentation and lagering tanks compliant with food industry requirements,
and of course aesthetics – because the equipment was to be part of the design.
Stage 2: Welding, prefabrication, assembly
Once the design was ready, we would start work. Our team would prefabricate and weld the pipelines using the TIG method, ensuring that each weld was smooth, tight and ready for many years of use.
There is no room for chance in brewing – that is why we would use orbital welding of thin-walled stainless steel pipes to obtain welds that were corrosion-resistant and easy to keep clean.
We would assemble everything so that it not only worked well, but also looked good – because guests see more than they think.
Stage 3: First brewing – no surprises
After the assembly was complete, it would be time for tests: we would check the tightness, CIP operation and temperature control. After everything, it would be time for the first brewing. It would go smoothly – no leaks, no problems. The installation worked exactly as it should.
Of course, this is an illustrative story – but if you are planning a restaurant brewery or are thinking about modernizing an existing installation, it is worth knowing that the process can go exactly like this: without stress, with full technical support and in a reasonable time.
In conclusion
The truth is: a good brewing installation is the basis. It does not matter whether you brew 500 liters a month or 50,000 – what counts is precision, cleanliness, safety and that everything works exactly as it should. Because when you trust your installation, you can fully focus on what you love – brewing beer that really tastes good.
