《濃縮咖啡物理學》由 Jonathan Gagné 撰寫，是一本清晰實用的指南，深入探討沖煮頂級濃縮咖啡背後的科學原理。Gagné 詳細解析了水化學、滲濾與萃取、研磨行為、粉餅準備、沖煮動態，以及壓力與流量曲線設定。他結合已發表的學術研究與原創實驗，將複雜的物理學轉化為可實際操作的步驟，幫助提升沖煮一致性、風味表現與工作流程。無論是初學者還是專業咖啡師，都能從中獲得啟發，精進濃縮咖啡技藝。
The chapter on water chemistry alone is worth the price—I finally understand why my tap water was ruining my shots. The way Gagné breaks down percolation and extraction made me tweak my grind and suddenly I'm pulling way sweeter espressos.
I’ve read a lot of coffee books but never one that breaks down percolation and puck mechanics this clearly—the water chemistry chapter finally made sense to me after years of guessing. The graphs and step-by-step explanations are worth the price alone, and I’ve already pulled noticeably better shots
The chapter on water chemistry alone was worth the price—I finally understand why my tap water was making everything taste flat. Gagné's breakdown of percolation and extraction made me rethink my whole puck prep routine.
