Adjust Your Roasting Profile for Ambient Temperature

My recent series on roasting green coffee beans at home took place during the winter months here in Southern California. I take my iRoast-2 home roaster outside onto the patio since if I use it inside it sets off the smoke detectors! You can buy a venting attachment but I don't have a range hood that vents to the outside, so that's a no-go for me.

Anyhow, with the arrival of warmer spring weather I noticed a big difference in the darkness of the beans using the same profile I have favored throughout the winter. The roasts have resulted in very dark beans, akin to French roast. The beans are also sweating oil which also is indicative of a dark roast.

So if you're like me and roasting outside, take into acount the ambient temperature when you're roasting. Small differences in the temperature makes a big difference to the outcome of the roast using the very same profile.

Happy roasting at home and saving money!
