Coffee roasting is complicated, but it doesn’t have to be hard. Through books, lectures, communities, and one-on-one coaching, I give roasters the tools to understand coffee and take control of flavor. Whether you need hands-on training at the roaster, mentorship over Zoom, or resources to teach your staff, you’ll find it here.

Reviews from Clients

  • A former client of Rob's breaking the surface of the grinds in a cupping bowl.

    Kirsty - Arrosta Coffee, New Zealand

    Rob was able to guide and assist Arrosta Coffee Roasting Co. to recreate our award-winning reference curves from our 15kg Toper drum roaster to the new Loring.  The results have been scalable and achieved with a more comprehensive understanding of the advanced Loring roasting system so that we are able to implement our philosophy of continuous improvement within our production function.”

  • Someone who has been inspired by Rob Hoos' coffee content over the years.

    Okan - @calibre.coffee in Istanbul

    What has always stood out to me is that while you're one of the more established and knowledgeable figures in coffee roasting and training, you are so genuinely willing to share your wealth of knowledge and experiences. In an industry where many tend to hold such insights closely, your

    openness is not only refreshing but also incredibly valuable. I'm truly grateful for your contributions and your commitment to helping others grow.

    Eric - USA

    His in person classes information and hands on experience were invaluable and Robs expertise in my opinion is second to none. Upon completion of the class, I had reputable educational experience on my resume to obtain a roaster apprentice position. Six years later I’ve progressed from apprentice to Production Roaster to Head Roaster to Director of Coffee with jobs in four different states.

    Mathison - USA

    My in-person roasting class with Rob was an incredible experience. I came away with a new framework for approaching roasting fundamentals as well as very specific steps that I was able to immediately implement in my business. From how to physically operate the machinery to understanding data to interpreting cupping results, every aspect was covered in depth. Rob is a talented instructor with an approachable style.

    Ben - Nincomsoup, UK

    My roasting journey began with a short introductory roasting webinar class from Rob, I found his warm and down to earth style approachable and non intimidating... I bought his 'Modulating The Flavour Of Coffee' quickly absorbing those principles into my workflow, followed by 'Tipping and Its Avoidance', and then his latest book 'Cultivar' which I recently purchased, absorbed, and baked in to my roasting approach. Needless to say I'm hugely in debt to Rob's work for helping me solve the puzzle of roasting.
