味觉审美因为时代变迁，地域差异，历史背景而存在着各自的偏好。Earthlings 咖啡工作坊创办人李威霆，从生命科学的视角告诉大家，咖啡的品鉴不应该有一套客观标准。因为主观的味觉偏好才能酝酿出世界多元的独特性。

Our perception of taste has evolved over time, affected by factors such as geographical contexts and historical background. Due to this, Kenny Lee, the founder of Earthlings Coffee Workshop, shared that the taste of coffee should not conform to a fixed set of criteria. It is our subjective preferences that have brewed the diverse taste of coffee that the world enjoys.
