What can you find in the Roast Curve Library?

The Roast Curve Library is a place where you can take a peek over the shoulder of your roasting peers. It’s a way of seeing how they approach a coffee and shape the curve. So if you’re stuck in a rut or need another perspective on a specific coffee, this is the place to be.

Within the Roast Curve Library, you find 18 Cropster roast curves developed by 13 coffee roasters. You can select a curve, download it for free, and use it as you see fit. And as a bonus, you get a free green bean poster of the specific coffee you’re exploring.

Ready to take a peek over the shoulders of industry peers? Read the instructions on how to use the curves within Cropster here. Happy discovering and roasting!
