What I Know About Growing a Coffee Business by Colin Harmon is a practical, direct and honest book about building a coffee company.
Written by the founder of 3fe in Dublin, the book moves beyond brewing theory and café romance, and focuses on the actual work behind running and growing a coffee business. It covers decision-making, margins, staffing, systems, service, growth, mistakes, and the kind of everyday realities that rarely make it into the public story of a brand.
It is especially useful because it does not treat coffee as something separate from business. The product matters, but so does the structure around it. Good coffee alone is not enough, and this book makes that clear without overcomplicating it.
For anyone running a café, roastery, wholesale operation, or thinking seriously about starting one, this is a sharp and useful reference from someone who has actually built it.
