The present invention provides a liquid catalyzing system for aging a liquid, such as alcoholic liquid, vinegar and soy sauce. In the present invention, a plurality of nano metal flakes are adopted as the catalyst and a liquid catalyzing system is particularly designed in the present invention for rapidly aging the liquid. By using the liquid catalyzing system, the liquid can be evenly mixed with the nano metal flakes in a reaction space constructed by a framework and a filter in addition, a disturb gas is inputted to the reaction space through a gas circulation loop connecting with the framework for treating a liquid flow disturbance to the liquid and the nano metal flakes, so as to accelerate a catalytic reaction resulted from the nano metal flakes to the liquid.
