Warm tips for using Filson carbonation stone:

  • Though Filson carbonation stones can be made into a wide range of micron rating, they are most effective from 0.5 to 3 microns. If smaller, the stone will become ealily clogged by proteins and organic material. If higher, the bubbles will be too large to dissolve into the beer.
  • You are recommended not to take the Filson carbonation stone directly by hand. The pores on the surface of the stone is really small resulting in easily blocking by the oil on your finger. Before touching it, you can wear a pair of gloves.
  • It is better to clean Filson carbonation stone regularly. You can clean it before or after each use to prevent the tiny pores from clogging. The right cleaning method will help extend the service life of your carb stone.

What is a Carbonation Stone?

Carbonation stone is also known as carb stone or CO2 stone. It is a porous body sintered with stainless steel materials like SS 304 or SS 316/316L. As you can see, the carbonation stone usually has a silvery appearance. And on the surface, if you are careful enough, you will find many little pores.

The carb stone is a versatile device used to carbonate beer, soda, water, or other beverages. By doing this, the drinks will stay a good taste and fresh. Also, it can remove the excessive quantities of dissolved air or oxygen from beer or water.

How does a Carbonation Stone Work?

When you equip the carbonation stone for your vessel, no matter a corny keg or a brite tank, you will finally get a content beer production in high yield.

Due to the professional sintering process, the carbonation stone is full of micron pores on its surface. The pores provide millions of ways for carbon dioxide to pass through. Once the stone is linked with accessories like hose pipes and meters, it can be put into use.

When the carbonation stone works, plenty of mini bubbles is generated. That’s CO2 passing through the stone. It contacts the liquid in the form of bubbles. Through its way to the liquid surface, the gas is fully dissolved.

How to Use a Carbonation Stone?

Filson carbonation stone is designed with flexible connections and multiple connection types to fit your different application use. It’s easy to install and disassembly to save much time.

When you finish the installation of your carbonation stone, you can carbonate the beer according to the following steps:

  • Make sure the beer is cold, generally between 1.1 – 4.4℃.
  • Settle the carb stone at or near the bottom of the keg/tank.
  • Increase the pressure to 1 – 2psi and stay for 4 – 5 minutes. At this time, you will hear the bubbles in the vessel.
  • Keep increasing pressure in 1 – 2psi and wait for another 4 – 5 minutes. Repeat the operation until the pressure is up to 14 – 16psi.
  • Now you may get a fair production. Try a sample glass. If it has reached the desired carbonation level, you can remove the stone or leave it inside, it doesn’t really matter. And then back the pressure down to serving psi.
  • If you are not satisfied with the carbonation level, keep increasing the psi in 1 – 2psi each time till you get the desired level.
How do You Make Carbonation Stone?

Different from traditional ceramic carbonation stone or naturally porous stone, Filson carbonation stone is a sintered stainless steel media. The first step of manufacturing a carbonation stone is to design. Our engineering specialist will help to design the most suitable carb stone for you.

Then the workers will begin to produce your carbonation stone according to the design drawing. Firstly, the stainless steel powder will be compressed using hydraulic and pneumatic presses which results in a semi-structurally solid part. Then the most important procedure is coming—sintering.

There are many details during the fabricating process, you may ask for a video to see the whole process of making a carbonation stone or ask us for more information.

What is the Method of Cleaning Clogged Carbonation Stone?

If you order a carbonation stone, it is possible to be clogged for its small pore size. A couple of main tips that will help you clean your carbonation stone better:

  • Remove your carbonation stone. Make sure that the pressure is out of your brite tank anytime you take off it or else, it’s just going to probably hurt yourself.
  • Be careful not to scratch it or ruin the surface area and don’t touch the stone directly with your hand. Maybe you need a pair of gloves at this step.
  • Take it off the assembly.
  • Flush it with water to make your carb stones last a lot longer. Put it onto the hot water cleaning hose for a couple of minutes with 185 degrees water. You will see a large quantity of polluted water coming out of the stone.
  • Remove the stone and you will have the stone itself, clear all the way through.
  • Put the carb stone into a basket and settle the basket into an ultrasonic cleaner. The sound waves burst to get into really microscopic pores and give a little bit of mechanical action to clean those pores.
  • Soak the stone in caustic solution for about 30 minutes and flush the solution with hot water.
  • Put it all back together. You can store it in a dilute acid solution and sanitize it for the next use.

After careful and thorough cleaning, it will ultimately lead to more consistent carbonation of your stone.

Do I Need to Use Carbonation Stone?

If you want to improve your beer yields, YES!

You can achieve a better CO2 diffusion efficiency by adopting a carbonation stone. The carbonation stone is sintered into a porous structure with numerous pores. It will create millions of fine bubbles during operation.

The bubbles are so small that they provide a large contact area between carbon dioxide and beer. As the bubbles rise in the beer, CO2 is fully infused. Finally, you get the carbonation beer in a short time.

Besides, the carbonation stone is the key to improving the taste and mouthfeel of beer or other carbonated beverages. At the same time, it keeps the freshness to prolong the shelf life of the drinks.

Does Carbonation Stone Size Matter?

Of course, it does.

The length and pore size are greatly related to the efficiency of CO2 to liquid. The longer the stone is, the faster the carbonation will be realized. But it must be suitable for your keg or tank, usually, a 6 – 10 inch carbonation stone is popular. If too long, your stone may be damaged.

As for the pore size or micron rating, it’s an important factor for practical operation. If the pore is too small, the carbonation stone becomes clogged too easily by proteins and organic material. If too large, the bubbles are too big and difficult to dissolve into the product resulting in uneven foaming of your beer. So the most effective accuracy of the carb stone is from 0.5 to 3 microns.

Choosing the right carbonation stone for your application is crucial. Specifications, like size, micron rating, and connection type, are possible to influence the actual efficiency. For any other points to be noted, you can consult Filson engineering sales.
