The path analysis method of eliminating preferred stimuli (PAMEPS) as a means to determine foam preferences for lagers in European judges based upon image assessment

摘要

Judges rated images of lagers at different stages of consumption displaying various levels of head and lacing. Judges expressed their preference for one of four beer images at each of three stages of consumption. In so doing, judges created a virtual beer "preference path". Judges then repeated the process as if the exact beer preference path they favored was unavailable, but any of the other 64 possible combinations was available. Judges continued to repeat this procedure until they had selected their top the five beer preference paths. We call this technique the "path analysis method of eliminating preferred stimuli", or the PAMEPS approach, which allows simultaneous determination of preference among and within stages of consumption. Sampling of Belgian, Finnish, Irish, and Scottish populations reveals no preferences for foam images among stages of beer consumption, but suggest that within different stages of consumption there exist preferences for specific foam types at different geographic localities.
