In the past I’ve written up lists of recommended reading, and there is always one question that comes up that, I have struggled to answer: “What book should I buy on coffee roasting?”
Until today the options have been limited to Ken David’s book, or the harder to find little books like Gerhard A. Jensen’s “Coffee Roasting”. Neither are likely to make you an better at roasting, whether you roast at home or roast commercially. Roasting is a tricky business, and learning to roast feels more like trial and error than anything else. Many companies consider their roasting techniques and approaches proprietary, and have traditionally been unwilling to share. I’m actually a believer in proprietary information, and when I found out Scott Rao was going to write a book on coffee roasting this inspired further action for me at work. I had little doubt that this was going to be a book that was going to make coffee, across the whole industry, significantly better. I have not been disappointed.
Writing about roasting chemistry is difficult, and I think Scott has done an impressive job in cutting to the chase and presenting the important stuff in a way that seems real and accessible. While we understand the Chlorogenic acids are important, the whole discussion of them in roasting or brewing often feels abstract – here they do not.
What most people will want to read straight away are the practical roasting sections. Scott himself acknowledges this, but I would heed his note:
“I implore the reader to study the entire book and not focus solely on the “how to” chapters. Experience with my previous books has taught me that readers who cherry-pick the parts that appeal to them end up missing some of the big picture, leading them to misapply some recommendations”
I’m not going to cover the practical information in the book, other than to say that it is valuable and I definitely learned a good deal on my first couple of read throughs. Discussion of Rate of Rise (RoR), development, and things like ΔT are important, useful and ultimately very helpful. Scott has a very practical, methodical approach and I have no doubt that we’ll be looking at how we can implement his advice in a variety of places at work. I’m also delighted to see a section on sample roasting – something that it is almost impossible to find any good resources on.
Some people will reject what is in here, as it is contrary to their practices or beliefs. We’ve presented roasting as an art, as a personal expression of a roaster, so opinions that don’t validate what some people do can feel like criticism. They’re not – they’re opportunities to get better. Scott is cautious throughout to state that he’s trying to open up discussion. I think he’s given coffee roasters a base language that will allow us to better express the green coffees that we love, that we want to share and showcase to their full potential. I don’t think I absolutely agree with everything Scott writes, but I feel in a much better place when it comes to discussing that, arguing my point, and pushing my understanding of roasting to achieve the cup of coffee that we have in my heads.
You can buy the book direct from Scott. If you have any dealings with roasting coffee then I suspect this may be the best $45 you’ll spend.
