What Equipment Do Breweries Usually Use To Measure Pressure During The Beer Production Process?

Alcohol has been a part of human societies for a very long time.

With its many variants, in terms of preparation styles and concentrations, it has been an integral part of daily life throughout the world.


One such variant happens to be the beer.

The beer industry is today one of the largest beverage sectors of the economy, and worth billions across the world.

Also, the industry is expected to grow well into the near future, given that the market is steadily increasing throughout the world.


When it comes to the actual manufacture of beer, there is a lot that goes into the making of the finished good.

Indeed, if there is one thing many people are interested in knowing about beer, it would be the details about the actual preparation.

Not many people are into beer just for celebrations. On the contrary, they are interested in the way it is produced, as well as the many elements that are involved in its preparation.


Of the many things that go into the manufacture of beer, there is one thing that stands out more than anything else; the measurements.

If there is one thing about the beer industry that is to be noted, it is the way attention is paid to detail. Given that the smallest variations can alter the taste of the finished product, brewers pay a lot of attention to ensure that the ideal conditions during the beer preparation process.

Among the many values that are to be measured at the time of beer preparation, one of the most important is pressure.

When it comes to measuring the pressure in breweries, there are a few pieces of equipment that are used.

Of them all, one of the most important is a device called a Manometer. Manometers are used extensively across the beer industry, to measure pressure during the beer preparation process.


The Manometer

The manometer is a standard device used for the purpose of measuring pressure.

The device is not exactly something specific to the beer industry. On the contrary, it is something that can be use for a variety of applications beyond the scope of breweries. The measurement of pressure in general, is done using the international unit of measure, known as Pascal or Pa. This is however not the case when it comes to technical applications, such as beer making, where the standard for measurement is what is called a ‘bar’ or ‘pounds per square inch’. For reference, 1 bar of pressure is described as 100 kPa. The manometers measure the pressure in relative terms, where the pressure within a system is compared to the ambient pressure.

The usage of manometers is extensive throughout the brewing industry. Used on manometers is something that can be observed extensively across the beer making process, from the beginning to the end. Some of the places where they are used are mentioned in the list below:

  • Carbon Dioxide –Carbon dioxide is a byproduct generated when the ingredients are fermented by the yeast. This is something which is common in both the fermentation as well as the lagering tanks.
  • Piping Systems –There is a lot of transfer of liquids throughout the beer manufacturing process, whether it is the water, waste or the alcohol itself. From the time when the fermentation process begins, until the time when the finished beer is packaged, there is a lot of piping that is required to keep the entire system running.
  • Dispensing Systems –This is another place where there is a need for manometers. Given that the movement of beer has to be done at a stable rate, in order to maintain its consistency and flavor, there is a need to maintain a steady pressure throughout the system, which manometers help in ensuring.
  • Pneumatic Valves –The control of liquids and gasses across the breweries are done with the help of pneumatic valves. This is yet another place where the use of manometers can be found.
  • Bottling Process –The bottling process is one of the last processes in the beer making process, before the finished products are shipped to warehouses or the markets. This is another place where the measurement of pressure is required, so as to ensure a secure and sturdy seal.

The Working of a Manometer – The average manometer can come in a variety of different constructions. The manometers used in the modern day beer industry are usually those made from spring-loaded devices. These tend to be round and made using a variety of materials such as plastic, stainless-steel, copper, etc.

The element which senses the pressure is usually made from a bourdon tube or a diaphragm. The way in which the device works is usually with the help of what is called the ‘Piezoelectric Effect’, where movement (when applied on certain materials or crystals) is converted to electric charges. These charges in turn are converted into readings and measurements.

Other ways in which the measurements are generated include, among others, strain gauges, inductance measurements, etc. These are also fairly common throughout the beer industry.

The device consists of an entry point, where gases or liquids are allowed to enter. Upon entry, they act on the detecting mechanism, which in turn generates the necessary readings. In addition to this, they also contain another point for the entry of the medium in the surrounding environment, the measurement of which helps in the generation of relative readings.

The Measurements – Given that the environment in the beer manufacturing process tends to change from time to time, the readings in the manometer are taken at routine intervals. This helps to ensure that the pressure in the system remains stable at all times.

The exact standards for taking these measurements will vary from brewer to brewer. There is no specification with regard to how frequently the measurements are to be taken by the people managing the brewery.



As a whole, there is indeed other equipment as well that are in use across the beer industry.

The above mentioned list is just some of the most important and commonly ones that can be found across the modern beer industry.

Why Are Most Brewery Equipment Made Of Stainless Steel?

The alcohol industry is one of the largest in the entire world.

With annual revenue that runs into billions of dollars, it is by far one of the most important industries in several economies.

And this is true for almost all kinds of alcohols, ranging from beer to whisky and everything in between.


When it comes to the preparation of beer, one of the many things that people notice is that much of the equipment happens to be made of stainless steel. It is very rare that the standard equipment used in breweries is made of anything else.

While many consider this to be a standard industry practice and move on, others tend to ask questions; questions such as,

“Why are most brewery equipment made of stainless steel?”


And indeed, this is an important question when it comes to the brewing industry. There are several reasons why stainless steel is used for the brewing process. The reasons are as given in the list below:


  1. It is part of the evolution of the industry  

There was a time in the history of beer, when the drink used to be fermented in caskets made out of wood such as oak. In fact, most people still think that the beer they drink is produced in these barrels, when the reality is actually quite different. The fact is that almost no modern brewery produces alcoholic drinks in traditional wooden barrels; even if they do, it is largely done as a ‘tradition’ or ‘relic’, rather than standard industry practice.

The fact is that most modern breweries produce alcoholic drinks in stainless steel barrels or tanks, with some exceptions.

One of the most important reasons is simply because of the way the industry has evolved. The change of material happened to be a part of the larger industrial transformation.


  1. Stainless steel equipment is easier to maintain

This is by far one of the biggest advantages of using stainless steel equipment.

When compared to wood caskets, it is very easy to maintain steel equipment. From unwanted residues to waste products, it is possible to have all of them eliminated with ease in the case of stainless steel equipment.

The reason for this is simple. Stainless steel is tough and offers a fairly smooth and sleek surface, which allows for the use of everything from abrasive cleaning tools to harsh chemicals, which is simply not possible in the case of wood.

Wood, on the other hand, offers a fairly rough surface, which tends to chip, break and warp with the passage of time. All of this makes it very difficult to wash and maintain the equipment.


  1. Stainless steel equipment doesn’t leak

Another advantage of stainless steel equipment is that it is leak proof.

There is simply no chance of leakage, unless there is a hole of some sort. Given that the material is fairly tough, it is very difficult for any sort of leakage to emerge from stainless steel equipment.

This is however not the case when it comes to wood. Although wooden caskets and other such equipment are fairly tough and waterproof, they aren’t really one single unit, but rather made out of numerous individual units. In the long run, the spaces between these units or pieces can give way, allowing for leakage.


  1. Stainless steel doesn’t degrade

This is one of the biggest reasons why stainless steel has become popular.

One of the biggest problems that old breweries had was that the caskets, among other equipment, would fall apart with the passage of time. This was because most of them were designed from wood, which tends to decay with the passage of time. Whether from external factors like rot or insects like termite, the fact is that wood always degrades with the passage of time.

Stainless steel on the other hand is a very long-lasting and rigid material, and doesn’t have issues related to iron such as rust. With very few exceptions, there is no loss of structural strength or integrity in stainless steel. As a result of this, people using stainless steel in beer manufacturing found it to be a very effective and efficient material choice.


  1. The absorption of chemicals is not an issue in stainless steel

Another important point that is to be mentioned here is the ‘absorption’ issue.

Wood tends to contain a variety of materials, which may ‘leach’ into the beer. While some of it has been used to provide a ‘flavor’ to the beer, it may not always be the case in others. On the contrary, there is a possibility that anything harmful that might have existed in the wood might end up contaminating the beer.

Stainless steel on the other hand, is not something that ‘leaches’ any chemicals into the beer. On the contrary, it tends to maintain a steady flavor in the beer throughout the fermentation process as well as beyond.


  1. Stainless steel is considered eco friendly

The manufacture of traditional equipment usually involved the usage of wood like oak.

While plentiful before and in many cases even now, the fact is that it does require a great deal of timber to manufacture the equipment of any standard brewery.

This has considerable environmental impact when applied on a large scale, often leading to the loss of great many trees. In addition to this, not all trees can be used for the manufacture of beer equipment, since they need to be of a certain thickness before they are ready for harvest. And given that the beer demand is rather large in many countries, it would be environmentally destructive to have all of the beer made in wooden equipment.

This is where stainless steel is a great choice. Given that it involves no trees altogether, it serves as a useful replacement alternative for the beer industry. In this regard, stainless steel is a fairly eco-friendly alternative, in comparison to the cutting of trees.


In all, the above mentioned reasons are some of the most important reasons as to why beer is manufactured using stainless steel equipment.

It should also be added that the industry hasn’t entirely shifted to the use of stainless steel. On the contrary, there are many people who still cling on to the old ways, largely out of nostalgia for tradition and history.

But the fact is that stainless steel is here to stay in the beer industry, and will be around for a very long time.

Nano Brewery, Your First Step!

We have all heard a lot about nano breweries recently and most of us are aware of what it would be like because of the obvious name. No matter how much we hate science, we all admit that terms like micro, nano, pico is something we learnt through it, for people who love science, well this concept is now not just limited to your field. Nano breweries system have been a new trend for quite a while now and have been a profitable way to earn some one of the basic necessities of life: MONEY!

nano brewery

As the name suggests, it is a small set up and is assumed of producing maximum three barrels of beer in one batch. Another specification about this type of brewery could be regarded as the breweries which can make up to 2000 barrels in one year. We do agree that it is a nano brewery (considered to be quite small) but it does not in any way offers that the rules that are applied to micro or any other kind of breweries could be exempted for this one, you still have to abide by all the laws imposed by the state for brewers.

After going through all these basic points, do you still plan to become a brewer? If the answer to this question is yes, then here is to why you should consider nano brewery as your first and foremost option, especially if you are new to the business:

  • Craft Beer:

We all know that the importance of craft beer is increasing day by day and if you consider yourself to be an expert at that, micro brewery is the best way to test it. Since it is not a large scale business, you always have room for experiment. You can try different combinations and come up with the best one which is appreciated by the public of your locale.

  • First Step:

Business has always been and will always be risky. One cannot be hundred percent sure that the start-up they are thinking of will be a great success; this in no way means that being optimistic is a bad thing. You do need to play risky but the risk doesn’t necessarily have to be a big one, especially when you’re give an option to try it out at a much smaller and safer level, as in the case of nano brewery.

  • It is There to Stay:

From the past few years, it can be inferred that nano brewery is a success and that if you try it, there is a high percentage that you will also succeed. However, you do need to be strategic and come up with a plan because you surely do not want to stop at nano brewery. Remember, it is just your first step!

We hope that these factors will help you in deciding whether you should opt for nano brewery or not. Whatever your decision may be we can help.
