A method of analyzing the visually perceptible characteristics of foamable liquid, such as beer, comprises pouring a known quantity of the foamable liquid from a storage container into a clear beaker. A camera produces a video image of the beaker and its liquid and foam contents. A series of such image are periodically acquired over a definite time period. The images are electronically analyzed to derive numerical value indicating the different characteristics. A system for performing the method also is described.

A method of analyzing visually perceptible characteristics of foam which is formed when a foamable liquid is poured, said method comprising: (a) pouring the foamable liquid from a predetermined height at a set angle into a transparent container to generate a foam; (b) generating a series of two-dimensional video images of the container, as well as any liquid and foam within the container; (c) electronically analyzing the video images to derive numerical values quantifying the visually perceptible characteristics of the foam by defining a two-dimensional region in a video image and counting picture elements within the region that correspond to foam.
