Chemical Reactions Occurring in the Roasting Process (#)
„Establishing the thermal environment protocol for theideal roast is a balancing act. While it is desirable to maintain the BRRtemperature and energy levels until the target reactions are achieved,the BRR temperature is well above the carmelization temperature of sucrose.Because many roasting systems exhibit thermal hysterysis using simple temperatureregulating schemes, care must be taken not to allow the coffee mass toexotherm. Additionally, limiting the maximum environment temperature, MET,is also important. As previously mentioned, maintaining structural integrityof the cellulose matrix is of great importance.“

Why Home Roast? (INeedCoffee.com)
„There are websites, newsgroups and books dedicated to homeroasting. Of particular interest is the Home Coffee Roasting Mailing List at Sweet Maria's . Sweet Maria's is regarded as the premier resource for the home coffee roaster. In addition to home roasting equipment, you can find a huge selection of green beans available for sale in small batches for very reasonable prices.“

The Coffee Review - the world's leading coffee buying guide
„But doubtless I also was reacting to the impact of varying roast strategies. Every detail of roasting impacts the final taste of the coffee - not only how "dark" the coffee is roasted but also how it is roasted - with what sort of equipment, with what intensity of air flow through the roasting chamber, with what succession of roasting temperatures, and so on. This is not to even mention the ultimate annoyance in roasting: That the same coffee roasted exactly the same way using the same computer-controlled profile may taste slightly different when roasted on two different days or even two different times of day, apparently owing to changes in ambient moisture, barometric pressure, residual heat in the roaster, and perhaps to the unexorcised ghosts of roastmasters past, perished from heat, exhaustion, and frustration.“

„A skilled coffee roaster knows exactly what a given roast profile will do to the taste of coffee. Try to connect with some local "artisan" roasting companies. The purpose is to receive (free) training on their roasting machines in exchange for help with packaging the coffee, cleaning and/or repair work.“

CoffeeKid - A Home Roasting Primer
„Other roasters are around too: The second generation Fresh Roast has been updated, and now instead of roasting 2 ounces, can do 3.5, or about the same amount a popcorn popper can. At about $60, this is the cheapest regular price for a dedicated coffee roaster available today, and it does do the job pretty well.“
