Sensory Tea Analysis - Mastering Flavor Chemistry and Extraction #1004431

This book provides a detailed exploration of the principles behind tea sensory analysis, connecting the chemical foundations of flavor with practical tasting and brewing techniques. It begins by examining the fundamentals of tea flavor chemistry, detailing the significant role of polyphenols in tea. You will learn how compounds such as catechins and theaflavins contribute to the astringency, body, and color of the final infusion. The text also covers key active substances, including the relationship between L-theanine and umami taste, as well as the bitter components of caffeine and the L-theanine caffeine ratio. The second section focuses on controlling the extraction process. It explains how variables like brewing temperature, tea and water composition influence the resulting flavor profile. Readers will gain an understanding of the tea extraction curve and how to apply it in practice. The material addresses the effects of leaf-to-water ratio and leaf shape on extraction speed, with specific attention given to methods like gongfu brewing and cold brewing. A systematic approach to tea sensory analysis is then presented. This part guides you through the phases of visual, olfactory, and gustatory evaluation. It introduces tools such as the tea aroma wheel to help classify and describe sensory perceptions, enabling the creation of precise and structured tea tasting notes. The final chapters delve into advanced flavor profiling. You will learn to identify sensory markers related to processing steps like oxidation and roasting, as well as to recognize characteristics influenced by terroir, cultivar, and cultivation methods. This comprehensive overview is designed to deepen your understanding of tea theory and enhance your ability to analyze and appreciate the complex world of tea.
