Force carbonating beverages.

Set your regulator to about 2 psi, and the gas will be forced through the millions of tiny pores in the stone, which dissolves the gas into the liquid. Your beer will be carbonated overnight.

You will need a homebrew kegging outfit with CO2 tank, regulator, lines, and a keg. Simply attach a 24" length of ¼” ID tubing to the gas side dip tube of your keg with a worm clamp. On the other end of the tubing, attach the diffusion stone using another clamp.  There are charts available online and in books for exact levels of temperature and CO2 pressure to achieve desired carbonation levels. Following is an example for average carbonation in beer: Chill the beer to 40 F. Adjust the regulator to 2 PSI and attach the gas disconnect. Every 3 minutes increase the pressure 2 PSI until 12 PSI is reached. At this point the beer will be carbonated, but it won’t hurt to leave it alone in the refrigerator for a few days under pressure.

The best way to describe it is to visualize an aerating stone that is commonly used for brewing or carbonation.   Basically it’s a porous stone that allows gas pumped out of it.   As the gas comes out as fine bubbles, you are maximizing the surface area between the gas and the liquid aerated on.   For this reason, carb stone or carbonating stone is used to speed up the carbonating process of beers.
