Two-sample preference test (Nitenshikoho)

The two-sample preference test (nitenshikoho) is a method used in tasting and evaluation, mainly in sake tasting and assessment settings. In this method, a taster is presented with two sakes (Sake A and Sake B) and asked to choose which one they prefer. This yields a sensory evaluation based on personal preference and makes it easier to compare the characteristics and quality of the sakes. The two-sample preference test clarifies subjective evaluations and is an effective way to understand consumer preferences.
