Preface

*Coffee - Production and Research* presents a diversity of important issues related to coffee, with an emphasis on the science of coffee growing. Coffee is one of the highest value commodities traded worldwide. Cultivated and consumed widely, it generates progress for both the economy and society.

Coffee growing is located in tropical and subtropical regions. Coffee can be exported and imported in different types: green beans, roasted and ground coffee, and soluble coffee. Production is significant in about 60 countries from different continents. Coffee production stands out on the American continent, followed by Asia and Africa (origin of coffee).

There are more than a hundred coffee species in the world, but only two have economic value: *Coffea arabica* L. and *Coffea canephora* Pierre ex. A. Froehner. The other species are important too, but in general they are more used in breeding programs.

On a large scale, there are countries that grow only Arabica coffee (e.g., Colombia), some that grow only canephora coffee (e.g., Vietnam), and a few that grow both (e.g., Brazil).

Currently, there is a growing need to generate knowledge and technologies capable of optimizing the production of coffee in different types of cultivation, mainly to obtain a more productive and sustainable coffee crop in the face of current challenges.

Chapters in this book cover such topics as biotechnology, growing, harvesting, postharvest handling, quality, chemistry, commercialization, and byproducts of coffee.

I am very grateful for the opportunity to edit this book. I want to thank the authors and co-authors who contributed to the construction and quality of this volume.
