对不同年份的31个特制茯砖茶样品进行感官审评,从样品外形、内质、茶汤色差等方面比较和分析了不同年份茯茶的品质特征及差异。年份较长的茯茶干茶色泽为黑褐、灰褐或褐略带红,年份较短的茯茶干茶色泽多为黄褐、青褐;随着年份的延长茶汤色泽出现由橙黄-黄橙-红橙-橙红-红的变化趋势。茶汤的粗涩味随着陈化时间的延长逐步转化,原料较粗老的茯茶粗涩味转化较慢。研究从感官品质的角度揭示不同年份茯茶特征,为年份茯砖茶评鉴提供参考。

：In order to study the aging mechanism of Fuzhuan brick tea, organoleptic evaluation was carried out on 31 samples of the same grade but produced in different years by Yiyang Tea Factory in Hunan Province. The appearance, liquor quality, chromatic aberration were compared and analyzed. The results showed that the old Fuzhuan brick teas were more likely changed to dark brown, gray brown or brown tinged with red. Relatively, the color of Fuzhuan brick teas with short term storage tendered to be green brown or yellow cinnamon. As the extension of storage time, the changes of color of soup were from orange-yellow, orange, red-orange. orange-red to red. The soup of new tea was brighter than the old tea that had been kept for many years. The rough astringency taste was deceased gradually with aging. Fuzhuan brick teas which were produced by coarse raw materials were changed more slowly. This research investigated the quality characteristics and difference between the samples of different storage time. This study also provided some suggestions for Fuzhuan tea’s evaluation.
