Excerpt From the Article
“Many variables go into creating the perfect roast profile—equipment, the green beans, charge temperature, development time and more. One variable often overlooked is batch size. Batch size is just as it sounds—the size of the batch of coffee you are roasting, or how many pounds (or kilos) of green coffee you load into your roasting machine at a time. Roasting machines come in various sizes, and they are typically named to reflect drum capacity, or maximum batch size. …
However, the stated capacity for each roasting machine is not necessarily the ideal batch size for a particular offering. Other considerations come into play—your daily roasting needs, your machine’s heat source and power supply, green coffee density and other factors.”
