Abstract: A substantially salt-free carbonated beverage is produced using a pressurizable container comprising a carbonation chamber having an upper compartment for holding the chemical reactants, a means for separating gaseous carbon dioxide and solid or liquid reaction by-products and a lower compartment having a bottom sparger surface for releasing, as uniformly small bubbles, the generated carbon dioxide into a liquid to be carbonated. The separation means and sparger surface function to retain the chemical by-products of the reaction from the carbonated beverage.
