Roast approach

Blend the green beans before roasting.

Aim for an evenly developed light-brown finish. Use aroma and first-crack behaviour as references; do not rely on colour alone. Use similarly sized lots that roast compatibly. Begin with a small trial; if one component races ahead, choose more compatible lots for the next batch. If recording development time, use 14-18% of total roast time after first crack only as a trial window, not a universal endpoint. Decaf beans start darker. Judge development from aroma and roast behaviour as well as colour. Rest 4-10 days before the first comparison, then taste again as it settles. If the caramel goal feels flat: Try compatible lots with clearer caramel descriptors before changing the equal-weight ratio.
