Creative coffee roasting is an art. The key lies in leveraging both your triumphs and mistakes, and visualizing how all of your data works together to affect the final taste. Designed for specialty and prosumer roasters alike, Roastmaster paints the bigger picture. It enhances and speeds your workflow, compounding your achievements on your way to that consistently perfect cup!

Learn from the past and build a future:
Set a roadmap from any profile or roast with just a tap
Track any number of reading or control curves with various scales, like temperature, pressure or humidity
Target, inspect, and monitor data in the interactive analyzer
Stay on course with delta curves, level indicators, and temperature projections
Never miss a milestone with alarms, set-point alerts, and temperature trigger notifications
Save any roast as a profile, and build a custom library tailored to style or bean
View interactive roast log reports to compare metrics like drying time, development percent, moisture loss, and many others
Create roaster maintenance schedules to be reminded when individual tasks are due, and log details like service time and costs

Keep your green bean inventory in sync with your actual stock — automatically:
Beans or blends – let Roastmaster do the bean counting for you!
Set order reminders to alert you of low inventory
Record details like country, trade, processing, and more

Get creative concocting, tasting, and perfecting your signature blends:

Rate a morning pot of drip coffee, or score a professional cupping session:
Record extraction time, brew ratio, grind settings, and more
Score traditional attributes like aroma, body, and acidity with multiple cupping styles
Enter scores easily with interactive spider graphs
Visualize how cupping scores relate to all aspects of your workflow
