In this episode, Ryan and Zongjun (Sam) explore matcha through the lens of sensory science, flavor profiling, and quality assessment. They discuss cultural perspectives on taste, the socially-constructed nature of quality assessment, the role of descriptive analysis, and different frameworks for tasting. The episode concludes with comparative tastings examining the effects of temperature and dilution in matcha preparation, differences across matcha blends, and a comparison between two hand-picked, single-cultivar Asahi matchas made from Uji-grown tencha: one organic and kanreisha (shelf) shaded, the other conventionally grown and honzu shaded.
