Nothing to do with Sgt. Pepper, but all to do with home coffee roasting. My first home roast was on 7th November 2003. I had given up smoking around 3 1/2 months earlier, and had been retrenched for the second time a month earlier so had some time on my hands to take up something new. My first roast was of a Sumatran Mandheling, 80 grams in a popcorn popper. The roast was too dark because I hadn’t been able to identify the cracks as the beans heat up and make cracking sounds - firstly as the water in the beans heats and expands, and secondly as the coffee oils do likewise.
