CoffeeRoastMate

Master consistency in every batch — no matter the weather. CoffeeRoastMate is not just a timer; it’s a precision tool for anyone who cares about the science behind the bean — from home enthusiasts to small-batch professionals. Ambient temperature and humidity are invisible variables that can disrupt even a perfect roast profile. Cold air extends the Drying phase; humidity changes heat transfer. CoffeeRoastMate analyzes your local weather conditions instantly and helps you adjust your plan before you even drop the green beans.
