What is the purpose of standard procedures in coffee sensory evaluation?

The purpose of standard procedures in coffee sensory evaluation is primarily to eliminate personal biases. When evaluators follow standardized methods, it helps ensure that the sensory assessments are consistent and reliable across different tasters and evaluations. By adhering to these procedures, the focus shifts to the intrinsic qualities of the coffee itself, rather than the individual preferences or interpretations of the tasters. This uniformity allows for more accurate comparisons and conclusions regarding the flavors, aromas, and overall quality of the coffee being evaluated. Consequently, it leads to a more objective and repeatable assessment process, improving the validity of the sensory evaluations.
