The word "shrinkage" appears in literature both as a technical term and as a metaphor. In technical contexts—most notably in William H. Ukers’ All About Coffee—it refers to the measurable reduction in weight during the roasting process, with detailed discussions on how factors such as coffee variety, age, and even the quantity roasted affect the degree of shrinkage ([1], [2], [3], [4]). Such discussions even extend to practical recommendations, like limiting excessive watering to avoid reducing shrinkage beyond acceptable levels ([5], [6]). In contrast, Rabindranath Tagore employs the term metaphorically in Nationalism, describing the gradual diminishment of one's inner self or spirit as a form of "shrinkage" ([7]).
