What is Diffusion Stone? Do you Know How the Beer / Coca Cola Made ? 

Carbonation Stone, Actually not really stone, it is main made with porous metal like stainless steel etc, also

named 'Air Stones', main manufacture with sintered stainless steel in the market, are normally used to aerate

wort before fermentation, which helps ensure a healthy start to the fermentation process.


Diffusion Stones can be attached to compressed oxygen tanks or air pumps (such as those used with aquariums).

Dissolve different gases, such as Hydrogen, Carbon Dioxide, ChlorineOzone etc into liquids, in order to form

liquids rich in corresponding gases.

This "Stone" is made of stainless steel, so it's durable, easy to clean, and won't crumble in your wort after a few

uses like other materials! Less air pressure is required to force gas through the the 2 µm stone compared to

stones with smaller pores, making the 2 µm stainless metal diffusion stone good for use with small air pumps.


The Diffusion Stone is also suitable for force carbonation of beer inside a keg. But the larger bubbles produced

by the 2 micron pore size will limit the absorption rate of gas into the beer.

6 Tips You Should Confirm When Custom Your Own Diffusion Stone


Here are six tips to consider when customizing your own diffusion stone:

1. Determine the Gas and Liquid you will be using:

    Different gases and liquids have different properties, so it's important to consider these when designing your diffusion stone. For example, if you are using a gas with a high solubility in the liquid, you may need a larger or more porous stone to achieve the desired level of diffusion.

2. Consider the Size and Shape of the Stone:

   The size and shape of the stone will affect its performance and the rate of diffusion. A larger stone with a greater surface area may provide more efficient diffusion, but it may also be more difficult to clean and maintain.

3. Choose the Material for the Stone Carefully:

    Different materials have different properties that can affect the performance of the stone. For example, stainless steel is durable and resistant to corrosion, but it may be more expensive than other materials. Plastic may be cheaper, but it may not be as durable or resistant to high temperatures.

4. Decide on the Pore Size: 

    The pore size of the stone will affect the size of the bubbles that are released, which can impact the rate of diffusion. Smaller pores may release smaller bubbles, which may be more efficient at diffusing the gas into the liquid, but they may also be more prone to clogging.

5. Think About the Flow Rate:

    The flow rate of the liquid and gas through the stone will affect the rate of diffusion. A higher flow rate may provide more efficient diffusion, but it may also increase the risk of clogging or damage to the stone.

6. Consider the Cost and Maintenance: 

   Customizing your own diffusion stone can be a cost-effective solution, but it's important to consider the ongoing maintenance and replacement costs. Make sure to factor in the cost of materials, labor, and any additional equipment or supplies needed to create and maintain the stone.

Frequently Asked Questions of Diffusion Stone


1. What is a diffusion stone and how does it work?

A diffusion stone is a small, porous device used to introduce gases into liquids. They are often used in brewing and fermentation processes to oxygenate wort or add carbon dioxide to beer. Diffusion stones work by releasing tiny bubbles of gas into the liquid, which then disperse throughout the liquid and dissolve into it. This allows the gas to be evenly distributed throughout the liquid, ensuring that all parts of the liquid are exposed to the gas.


2. How do I use a carbonation stone to carbonate my beer?

To use a carbonation stone to carbonate your beer, you will need a keg or other container to hold the beer, a CO2 tank and regulator, and a source of pressurized gas (usually CO2). First, make sure your keg and carbonation stone are clean and sanitized. Next, attach the CO2 tank and regulator to the keg, and set the pressure to the desired level (usually between 10-30 psi). Then, connect the carbonation stone to the gas inlet of the keg using a gas line. Turn on the CO2 and allow the gas to flow through the carbonation stone and into the beer. After a few days, the beer should be fully carbonated.


3. Can I use a carb stone to carbonate other types of beverages besides beer?

Yes, you can use a carb stone to carbonate other types of beverages besides beer. The process is generally the same as carbonating beer, but you may need to adjust the pressure and carbonation time based on the specific beverage and desired level of carbonation.


4. What is the difference between a SS Brewtech carb stone and other carbonation stones on the market?

SS Brewtech is a well-known manufacturer of brewing equipment, including carbonation stones. SS Brewtech carb stones are made from high-quality stainless steel, which is durable and resistant to corrosion. They may also be designed with specific features, such as a fine mesh filter, that are intended to improve the performance of the stone. Other carbonation stones on the market may be made from different materials, such as plastic, and may not have the same level of durability or performance as SS Brewtech carb stones.

5. How do I properly clean and sanitize my carbonation stone?

To clean and sanitize your carbonation stone, first remove it from your keg or fermenter and rinse it thoroughly with hot water. Next, soak the stone in a solution of hot water and a brewing sanitizer, such as Star San or iodine-based sanitizers. Allow the stone to soak for at least a few minutes, then rinse it with hot water again. Be sure to clean and sanitize the stone every time you use it to prevent contamination of your beer or other beverages.


6. Can I use an inline carbonation stone in my keg system?

Yes, you can use an inline carbonation stone in your keg system. Inline carbonation stones are designed to be used in a keg system, where they are connected directly to the gas line that supplies pressurized gas to the keg. To use an inline carbonation stone, simply attach it to the gas line and turn on the gas. The stone will release small bubbles of gas into the beer as it flows through the keg, allowing it to be evenly carbonated.


7. Is a stainless steel carbonation stone better than a plastic one?

Stainless steel carbonation stones are generally considered to be better than plastic ones because they are more durable and resistant to corrosion. Plastic carbonation stones may break or become damaged over time, which can lead to contamination of the beer or other beverage. Stainless steel carbonation stones are also more resistant to high temperatures and are easier to clean and sanitize.


8. Can I use a stainless steel aeration stone to oxygenate my wort during the brewing process?

Yes, you can use a stainless steel aeration stone to oxygenate your wort during the brewing process. Aeration stones work by releasing small bubbles of air into the wort, which helps to promote healthy yeast growth and fermentation. To use an aeration stone, simply attach it to an air pump and immerse it in the wort. Turn on the air pump and allow the stone to release bubbles into the wort for a few minutes. Make sure to oxygenate the wort as close to the beginning of the fermentation process as possible, as oxygen is important for healthy yeast growth.


9. What is the purpose of a 2 micron diffusion stone?

2 micron diffusion stone is a type of diffusion stone that has very small pores, usually around 2 microns in size. This makes the stone capable of releasing very small bubbles of gas, which can be beneficial in certain situations. For example, a 2 micron diffusion stone may be used in situations where a high level of oxygenation is required, such as in the production of mead or cider. It may also be used to add carbon dioxide to beer or other beverages in a very controlled and precise manner.

10. How do I install a carbonation stone in my fermenter or keg?

To install a carbonation stone in your fermenter or keg, you will need to attach it to the gas inlet using a gas line. Make sure the stone is clean and sanitized before installing it. To attach the stone to the gas inlet, simply screw it onto the inlet using a hose clamp or other fastening method. If you are using a keg, you may also need to attach the stone to the gas line leading to the keg.

11. Can I use a carbonation stone to force carbonate my beer instead of using a CO2 tank?

Yes, you can use a carbonation stone to force carbonate your beer instead of using a CO2 tank. The process is generally the same as using a CO2 tank, except that you will need to find a source of pressurized gas other than CO2. Some options for pressurized gas include compressed air, nitrogen, or a blend of gases. Be aware that using a gas other than CO2 may affect the taste and appearance of the beer, so it is important to choose a gas that is appropriate for the style of beer you are brewing.

12. How do I know when it's time to replace my carbonation stone?

It is generally recommended to replace your carbonation stone every 6-12 months, or whenever it becomes damaged or clogged. Signs that it may be time to replace your carbonation stone include decreased performance, difficulty maintaining proper carbonation levels, or visible signs of damage or wear.


13. Can I use a carbonation stone to carbonate hard cider or other non-alcoholic beverages?

Yes, you can use a carbonation stone to carbonate hard cider or other non-alcoholic beverages. The process is generally the same as carbonating beer, but you may need to adjust the pressure and carbonation time based on the specific beverage and desired level of carbonation.

14. How do I properly store my carbonation stone when it's not in use?

When storing your carbonation stone, it is important to keep it clean and dry to prevent contamination. After cleaning and sanitizing the stone, allow it to dry completely before storing it. You can store the stone in a dry, airtight container or bag to protect it from moisture and contaminants.

15. Is it safe to use a carbonation stone with food-grade CO2?

Yes, it is generally safe to use a carbonation stone with food-grade CO2. CO2 is a commonly used gas in the food and beverage industry, and it is generally considered safe for use in brewing and fermentation processes. However, it is important to follow proper safety guidelines when handling CO2, such as wearing protective gear and avoiding inhaling large amounts of the gas.
