This is a highly curated list of reference material, and proven product suggestions. Books, monographs, websites, channels, and podcasts that educate. It also include products and hardware I have extensive experience and history with. I use read and suggest it regularly.
I have subscribed to Roast for 10+ years. Its my go-to for current coffee knowledge. By far the most consistently educational trade periodical in specialty coffee. Each issue covers roast profiling, green evaluation, origin reporting, sensory science, and roastery operations at a depth that books rarely match for current practice. The technical articles in particular — on roast chemistry, water chemistry, and equipment — are written by working practitioners and researchers rather than generalists. Back issues reward reading; the archive is a record of how specialty roasting has developed as a discipline.
About the author.Roast Magazine was founded in Portland, Oregon in 2003 and remains the primary trade publication for the specialty coffee roasting industry. It publishes peer-reviewed and practitioner-authored content alongside industry news, and is the publisher of The Book of Roast.
From Beans to Brewing — Coffees Explored, Explained and Enjoyed
Mitchell Beazley·Third edition
Substantially revised to reflect the changes in specialty coffee since 2018 — new processing methods, expanded origin coverage, and updated brewing science. The two editions reward reading together; the differences between them are a record of how quickly the industry has moved.
About the author.James Hoffmann is a London-based coffee writer, consultant, and World Barista Champion (2007). Co-founder of Square Mile Coffee Roasters. The World Atlas of Coffee has sold over a million copies across its editions.
From Beans to Brewing — Coffees Explored, Explained and Enjoyed
Mitchell Beazley·Second edition
A comprehensive survey from farm to cup — cultivation, processing, trade, roasting, and brewing — organized by origin and written with precision. The standard single-volume reference for understanding where coffee comes from and why it tastes the way it does.
A really interesting read from Rob. Since he turned his attention to dark roasting — a style I (along with others) dismissed in specialty circles, but one with its own craft logic and sensory vocabulary. This book examines how high-development roasting affects acidity, body, and sweetness; when dark roasting serves the coffee rather than obscuring it; and how to approach profiling decisions at the darker end of the spectrum with the same intentionality applied to light roasting. A simple, but great read.
The Craft of Coffee Roasting from Bean to Business
Roast Magazine·First edition
This thing is so solid. Four parts, (intro, green coffee, roasting, and operations) with numerous chapters, is a 450+ pages long reference. An anthology drawn from Roast Magazine covering the full arc of the roasting trade. Particularly strong on the intersection of sensory evaluation and roast chemistry. That section is 3/4ths of the book.
About the author.Roast Magazine is a Portland-based trade publication founded in 2005, serving the specialty coffee roasting industry. The Book of Roast draws on over a decade of that editorial archive.
Another solid Hoos book. A foundational volume in Hoos's series. Examines how roast profiling decisions — rate of rise, development time, total roast time — directly shape the flavor profile of a finished coffee. Argues that the roaster's primary lever is not roast level per se but the specific thermal trajectory applied to a given coffee batch.
About the author.Rob Hoos is a Portland-based coffee roaster, consultant, and writer. He has contributed to the SCA's educational curriculum and is among the most widely read voices in specialty roasting craft.
Dude keeps knocking 'em out. Maps the interdependencies between the major sensory attributes of roasted coffee — acidity, sweetness, body, and finish — and how roast development decisions shift the balance between them. Useful for any roaster trying to diagnose why a profile is producing the wrong cup rather than simply adjusting by feel.
I met Scott at SCA Atlanta years ago. Really approachable dude with SOOOO much knowledge. The standard technical reference for serious roasters worldwide. Rao covers green evaluation, roast chemistry, heat transfer, drum dynamics, profiling, and quality control with a precision the existing literature had not approached. Any vocabulary now used in specialty roasting to discuss profiling derives largely from this book.
About the author.Scott Rao is a coffee consultant, educator, and writer widely regarded as the most analytically rigorous voice in specialty coffee. He has consulted for roasteries on five continents and written four books covering espresso, filter brewing, roasting, and coffee science.
A full-chain account of coffee craft at Blue Bottle — origin sourcing, green evaluation, roast philosophy, and detailed brewing methods. Freeman writes as a practitioner who understands why things work, not merely that they do. A foundational text of the specialty era.
About the author.James Freeman founded Blue Bottle Coffee in Oakland in 2002. His approach — small-batch roasting, rigorous sourcing, and a commitment to freshness — helped define the aesthetic and operational standards of the third wave.
An Expert Guide to Preparing Espresso, Coffee, and Tea
Scott Rao·First edition
A systematic treatment of espresso and filter coffee preparation for working baristas who want to understand the mechanics of extraction. Covers machine calibration, grinder geometry, dose, yield, and troubleshooting with a clarity largely absent from the coffee literature at the time. The text that established Rao's reputation.
The book that introduced home roasting to a generation of American coffee enthusiasts, including me. A single craigslist sourced HotTop roaster and zero clue, I began a voyage 2010. This book was my first. It covers the history of the practice — standard in most households until the late nineteenth century — alongside practical instruction on equipment, green sourcing, and flavor evaluation. Essential for understanding how to create a story to coffee roasting.
About the author.Kenneth Davids is an American coffee writer and founder of Coffee Review, the long-running publication applying a structured 100-point rating methodology to coffees from roasters worldwide.
Newer book, great read. A never seen anywhere concept of how botanical cultivars can shape the sensory potential of a roasted lot. Hoos surveys the major cultivar families and argues that cultivar awareness should precede roast profile decisions. Short, dense, and practically essential for any roaster evaluating roasting approaches.
Independently published / Royal Coffee·First edition
A systematic treatment of green coffee as a material — physical properties, processing methods, origin variables, and evaluation frameworks. Chapters on moisture content, water activity, density, and screen size are particularly useful for roasters who want to understand why green behaves differently across lots. The sections on processing variants are among the best available.
About the author.Chris Kornman is a coffee educator and green coffee specialist, formerly Director of Education at Royal Coffee. He has written extensively on green coffee evaluation and origin for Roast Magazine and The Crown.
Kew Publishing / Royal Botanic Gardens, Kew·First edition
Such a great book giving a topographic reference point to coffee diversity. A definitive scientific and geographic reference on Ethiopian coffee — the birthplace of Coffea arabica and the source of the most genetically diverse coffee germplasm on earth. Documents over 1,000 distinct coffee populations across Yirgacheffe, Guji, Sidama, Kaffa, and other regions. For a roaster sourcing Ethiopian lots, this volume reframes what regional names actually mean.
About the author.Aaron P. Davis is a senior research leader in coffee at the Royal Botanic Gardens, Kew, with over two decades studying wild Coffea species. Tadesse Woldemariam Tadesse is an Ethiopian botanist whose fieldwork forms the empirical backbone of the atlas.
Addresses green coffee procurement as a quality decision rather than a logistics one. Covers the relationships between roasters and importers, how to evaluate green samples, what origin and processing claims actually mean in practice, and how sourcing choices constrain or expand what is possible at the roaster.
About the author.Rob Hoos is a Portland-based coffee roaster, consultant, and writer. He has contributed to the SCA's educational curriculum and is among the most widely read voices in specialty roasting craft.
This book blew my mind. What a super detailed trajectory. A rigorous, quantitative treatment of filter coffee brewing grounded in fluid dynamics, thermodynamics, and mass transfer. Gagné applies the analytical discipline of scientific research to coffee extraction — examining how grind particle size, water temperature, flow rate, bed geometry, and turbulence interact to determine what ends up in the cup. Chapters on channeling, bypass, and the relationship between extraction yield and TDS are particularly valuable for anyone who has moved past intuition-based brewing.
About the author.Jonathan Gagné is a research scientist at the Institute for Research on Exoplanets in Montreal. He has applied his background in astrophysics to coffee brewing with unusual rigor, and his collaboration with Scott Rao brought The Physics of Filter Coffee to a wide professional audience.

Video & Channels
James Hoffmann·YouTube Channel
James Hoffmann
Uh....the GOAT in coffee. His knowledge and geekery are second to none. The most technically rigorous coffee channel available. Mr "best hair in coffee" James Hoffmann covers brewing science, equipment evaluation, roast analysis, and origin with the same precision as his books. His coffee delivery and devices videos are second to none.
Rao's channel is a direct extension of his consulting and writing practice. Videos cover roast profiling methodology, green evaluation, charge temperature, rate of rise, and the reasoning behind specific profiling decisions. Particularly valuable for roasters who have read The Coffee Roaster's Companion and want to see the concepts applied in real time.
Practical, craft-focused roasting content covering profile development, green evaluation, and the day-to-day decisions of small-batch roasting. The channel approaches the subject from the perspective of working roasters rather than theorists — useful for seeing how profiling concepts translate into actual drum decisions. In my view, Ingo at Roast Rebels is second only to Hoffman, in being a treasure of connectiveness and education.
Having been to 2 trade shows (Seattle and Atlanta) I have learned so much via the SCA. It publishes research, cupping protocols, green grading standards, and technical white papers that form the operational vocabulary of specialty coffee. The Water Quality Handbook, the Green Coffee Grading protocols, and the Sensory Skills curriculum are all available here. Essential reference for anyone working to a professional standard. The SCA really drives educational consistency across a varied and diverse industry.
Research-driven content on coffee sensory science, roast chemistry, and quality evaluation from Danish coffee scientist Morten Münchow. The articles on Maillard reactions, acidity development, and the relationship between roast degree and sensory attributes are among the most rigorous freely available writing on roast chemistry. His small online class really taught me tips and tricks for appropriate level roasting.
The home of Hoos's monograph series — the most practically useful short-form writing on roasting craft available. Modulating the Flavor Profile of Coffee, Relationships, Sourcing, Cultivars, and Exploring the Dark Side of Coffee are all available here. Each publication is direct, based upon experience. If there is a single person who have that has shaped how I think about profiling decisions, it is Rob Hoos.
Sweet Maria's is a home-roasting retailer and one of the most thorough sources of green coffee information available. Their lot descriptions include cupping scores, roast recommendations, farm and processing notes, and varietal detail. Farm notes for several Judith Creek lots draw directly from their research.
Willem Boot & Team·Green Coffee Retailer & Reference
Coffee Shrub
Coffee Shrub is a green coffee retailer with deep roots in the specialty trade. Their lot notes cover origin, processing, and flavor expectations with the same seriousness as their sourcing. Farm notes for several Judith Creek lots draw from their research.
Another go-to source. One of the most transparent and editorially serious green importers in specialty coffee. The their pages go well beyond standard spec sheets — origin context, farm-level detail, processing notes, and honest sensory observations. The Crown editorial arm publishes origin reports and roasting observations from their Oakland lab that are consistently worth reading. An essential reference for understanding what is available and why it matters.
The primary scientific body focused on coffee agronomy, cultivar development, and climate resilience. The WCR Sensory Lexicon — a standardized vocabulary for describing coffee flavor attributes with reference standards — is the most rigorous tool available for building a consistent sensory language. The Arabica Varieties Catalog is an essential reference for cultivar identification.
Some highly detailed, long-form conversations on coffee chemistry, sensory science, and roasting research. Münchow interviews researchers and practitioners whose work sits at the intersection of science and craft. Episodes on roast development, acidity formation, and the chemistry of sweetness are particularly relevant to profiling choices.
The SCA's official podcast covers research, industry trends, and practitioner interviews across the full supply chain. Episodes on green evaluation, roasting science, and sustainability are consistently substantive. The archive includes conversations with researchers whose work appears in the SCA's technical publications.
Royal Coffee's editorial arm publishes origin reports, green evaluation notes, and roasting observations from their Oakland lab. I have purchased numerous coffees from Royal. Their writing is practitioner-level — specific, honest about uncertainty, and grounded in actual selected coffee rather than generalized origin narratives. The Crown Jewel notes, in particular are a model for how to write, roast, and live the coffee life.
Straight outta Lake Pend Oreille (pon-der-ray) Idaho. If a Probat is German quality, a USA made Dietrich is the counterpoint. They build drum roasters for all sizes and levels. Their airflow systems have improved greatly over the years. Their machines now really do what you need, which means the roaster's decisions are the limiting factor, not the equipment. Built to last and supported seriously. My full week class was taught by Steven Dietrich, more than 10 years ago, was the last roasting class Steve taught before he retired from the business, the company his father founded.
Such a reputation. The standard against which most professional grinders are measured. Mahlkönig's burr geometry and grind consistency hold up under sustained use in ways that matter for both cupping and production. The EK43 in particular has become a reference tool for filter and cupping work across the specialty industry. I have hands on, working knowledge with Mahlkonig grinders. Simply unmatched German quality with boilerplate production.
La Marzocco machines are built around thermal stability and pressure consistency — the two variables that matter most for repeatable espresso extraction. The dual boiler design and saturated group heads have set the standard for professional espresso equipment for decades. Reliable, repairable, and worth the investment. These guys produce some the absolute best machines in the business.
I love Hario products. Thoughtfully designed brewing hardware built for precision and durability. Hario's V60, Switch, and kettle range have become reference tools for filter brewing — equipment that rewards careful technique and gets out of the way. The borosilicate glass construction and consistent manufacturing tolerances make them reliable for both daily use and filter coffee fun.
Yama produces borosilicate glass brewing and laboratory equipment — siphon brewers, cold drip towers, and glassware that bridges the gap between craft brewing and scientific precision. The cold drip tower in particular is a serious piece of equipment for slow extraction work. Built to a standard that holds up in daily use.
