摘要/Abstract

摘要： 祁红工夫、川红工夫和滇红工夫作为我国三大代表性工夫红茶,其冲泡工艺仍依赖个人经验,尚无科学的冲泡指导。以祁红工夫为试验对象,以萃取率（EY）和总溶解固体（TDS）为茶汤质量指标,采用生存分析法测定消费者对茶汤最佳风味平衡度和浓度的接受程度,建立祁红工夫冲泡控制图,并选用理想轮廓法（IPM）测试其在川红工夫和滇红工夫上的应用。结果显示,生存分析法确定了最佳EY为3.46%~5.68%、最佳TDS为0.14%~0.29%,最佳茶水比（g∶mL）为1∶20~1∶30,并以此建立了九宫格的祁红工夫冲泡控制图;评价员对川红工夫和滇红工夫茶汤的IPM测试发现,川红工夫的3泡茶汤均位于50%以内的核心理想区域,整体应用性良好;而滇红工夫茶汤位于20%以外的区域,评价员接受度较低,适用性较差。本研究建立的工夫红茶冲泡控制图可以有效指导中小叶种工夫红茶理想茶汤的冲泡,但对大叶种工夫红茶的适用性尚需完善。

Abstract: As three representative Congou black teas in China, Keemun Congou, Chuanhong Congou, and Dianhong Congou black tea still rely on personal experience in their brewing process, and there is no scientific guidance for brewing. This study focused on Keemun Congou black tea as the experimental subject, with extraction yield (EY) and total dissolved solids (TDS) as indicators of tea infusion quality, survival analysis was used to determine consumers’ acceptance of the optimal flavor balance and concentration of tea infusion. A brewing control chart of Keemun Congou black tea was established and the ideal profile method (IPM) was selected to test its application on Chuanhong Congou and Dianhong Congou black teas. The survival analysis identifies the optimal EY as 3.46% to 5.68%, the optimal TDS as 0.14% to 0.29%, and the optimal tea-to-water ratio (g∶mL) as 1∶20 to 1∶30, based on which a nine-grid Keemun Congou brewing control chart was established. Through evaluator validation via the IPM, it was found that for Chuanhong Congou, most of three infusions fell within the 50% core ideal zone, indicating good overall applicability. In contrast, first brew of Dianhong Congou black tea infusion was outside the 20% acceptability threshold, reflecting lower evaluator acceptance and poorer applicability. This study indicated that the brewing control chart established based on small-leaf Congou black tea can effectively guide the brewing of ideal tea soup for medium and small-leaf Congou black tea, but its applicability to large-leaf Congou black tea still needs to be improved.
