摘要
Method and apparatus for studying, as a function of time, the characteristics of a head of beer froth appearing at the upper part of a transparent container, such as a glass or the like, after the beer has been poured from a bottle or can, or has been drawn from a cask. The beer is drawn from the cask or poured from the bottle in a predetermined and reproducible manner in order to form the head of froth (m), and the variation in height of the said head is determined at pre-established intervals of time by image-forming means (40), advantageously a camera with semiconductors and associated with a microcomputer (53). Application to the study of the qualities of beer at the brewing stage or at the tasting stage after production. IMAGE
