Precision roast profiling is only the beginning. Roastmaster goes far beyond managing your workflow and cataloging your data. By integrating your workflow, data, and analysis, it reveals insights that would otherwise go unnoticed—the patterns within your data and the story they tell. Whether you're pursuing the perfect cup or a stronger bottom line, Roastmaster helps you understand how the pieces fit together—bringing a gestalt to coffee roasting. KNOW YOUR INVENTORY Your inventory is more than a tally. It's a living picture of your coffee’s potential. Every origin, process, harvest, lot, and purchase tells part of the story. Roastmaster makes every detail of your inventory easy to explore and understand visually. PLAN WITH CONFIDENCE Keeping inventory stocked is about more than avoiding shortages. It's about keeping the coffees you need when you need them. Roastmaster helps you leverage seasonal trends and historical usage patterns to plan your orders with confidence. MONITOR BEAN QUALITY Coffee is always changing. Harvests, seasons, and even individual lots all influence quality. Roastmaster preserves that history over time so you can understand how it affects both flavor and consistency from one roast—and one season—to the next. LOG VIRTUALLY ANYTHING Roasting is the heart of it all—and Roastmaster has plenty of heart. Whether you're logging temperatures from supported probe hardware, gas pressure from DIY Bluetooth electronics, or entering readings manually, Roastmaster adapts to the way you roast…and never forgets a detail. LEARN FROM EVERY ROAST Every roast is an opportunity to improve the next. Roastmaster helps you capture what worked, learn from what didn't, and build a library of profiles that evolves with your experience. Create profiles manually, from completed roasts, or even target previous roasts on the fly. STAY ON COURSE Monitor temperature projections, roast phases and key milestones in real time so you can make confident decisions as you roast. Profiles, targeted roasts or auto-trigger events can provide audible alerts to make sure you don’t miss a thing. ELEVATE YOUR WORKFLOW Spend less time preparing roasts and more time roasting. Roastmaster streamlines setup, lets you create new roasts from existing data, and even prepares production runs to meet a desired yield. CREATE YOUR BRAND TASTE–AND KEEP IT Beans change from crop to crop, but your signature flavor doesn't have to. Build a library of custom blends, experiment with snapshots to refine every recipe, and preserve the character your customers expect from season to season. EVALUATE FOR EXCELLENCE Every cup has something to teach. Whether you're rating a morning brew or conducting a formal cupping session, Roastmaster helps you capture the details with multiple tasting protocols, intuitive scoring tools, and visual comparisons that connect every evaluation back to the decisions that shaped it. READ THE STORY Why collect data if you never stop to understand the story it tells? Roastmaster's powerful analytics reveal how beans, lots, roasts, blends, and all their quality, varietal, and cost attributes shape both flavor and business outcomes. It helps you see the complete picture—and make better decisions because of it. Roastmaster is free to download and explore. Features vary by subscription tier. Learn more at rainfroginc.com.
