Guest dearknarl Posted May 20, 2005 Share Posted May 20, 2005 Gday guys, Is there a simple relationship between pressure and concentration of co2 dissolved in water at room temp? Or can someone point me in the direction of a graph? I'm interested because I would like to have an idea of how much CO2 there is in a beverage depending on the volume and pressure. Regards, knarl.

Hephaestus Posted May 20, 2005 Share Posted May 20, 2005 Yes there is a relationship. More practically: Advise the you use plastic bottles if you want more CO2 in your brew. Add no more than one tablespoon of sugar or one barley drop per bottle. If in crowns add no more than a teaspoon as the ywould explode on a hot day. i am assuming 375 mL bottles.

Primarygun Posted May 20, 2005 Share Posted May 20, 2005 Is there a simple relationship between pressure and concentration of co2 dissolved in water at room temp?

However, up to a point, if you want to increase the concentration, extra pressure from outside is required. Link to comment Share on other sites More sharing options...
