Although I have read a lot of books about coffee, I am still troubled: I don't know what kind of coffee beans I like. Because the brewing method has its own style, I don't know whether this brewing method is suitable. It doesn't taste good. How should I adjust it? My taste is slightly different from everyone else's, and I hope it can be closer to the taste I like... This book summarizes comprehensive knowledge from bean selection to extraction, and expounds the practical skills of "brewing methods" that Izaki Hidenori has taught in training around the world and can be used immediately. Through this book, start a journey to find your favorite "best coffee in the world".
