Carbonation Stone, a device used to diffuse carbon dioxide into beer. It may be made of naturally porous stone, porous ceramic, or finely sintered stainless steel. Usually used inside a brewery bright tank or a brewpub serving tank, the carbonation stone is a hollow cylinder, capped at one end, into which carbon dioxide is forced under pressure. The CO2 diffuses through the stone, emerging on the exterior in very small bubbles. Under pressure, the small bubbles of CO2 dissolve into the beer before they can reach the surface. Carbonation stones may also be used in-line. A carbonation stone can be used to carbonate flat beer, to add CO2 to beer with inadequate carbonation for packaging or service, or to scrub dissolved oxygen from beer or water.
How to Use a Carbonating Stone
Using a carbonation stone will cut down the time needed to carbonate the beer to about 1/2 hour.
- The beer needs to be cold, between 34 and 40 Ā°F.
- Once beer is done fermenting and ready to be carbonated, youāll want to attach your sanitized carbonation stone to the racking port of the conical
- Start with no pressure on the regulator and increase to 1-2 psi and let sit for about 4-5 minutes.
- Repeat the pressure increase in 1-2 psi increments waiting 4-5 minutes between increases until you are about 14-16 psi.
- Try a sample glass. If this is the desired carbonation level, you can either remove or leave in the stone and back pressure down to serving psi. If not, keep increasing the psi in 1-2 psi increments till you get your desired level.
How do I clean the carbonation stone?
After use, the carb stone should soak in brewery wash or similar product for at least 24 hours. After a good long soak, rinse with warm water while attaching the stone to a CO2 line to push all residual material and brewery wash out of the stone’s porous body. When ready to use again, we recommend one more rinse then soak with sanitizer for a few minutes.
