Add to cart Advanced Definition Roasting $750.00 Become a “master roaster” by creating your own custom roasting profiles using Sonofresco’s Advanced Definition Roasting (ADR) controller – the perfect combination to make a profitable difference in your business! The fundamental objective of good roasting should be to reveal the best flavors of any particular coffee. This is best achieved by roasting consistently in color and time-temperature profiles designed to match the characteristics of a particular coffee. Too fast a roast gives insufficient time for flavor development. A longer, light degree of roast allows the coffee to reveal its true flavors. Darker roasts develop caramelized flavors with a sweeter aftertaste, more suitable for espresso. Quick cooling following the roast helps stabilize the brightness of a coffee associated with high acidity. This is an upgrade kit for Pre-2014 roasters not equipped with Advanced Definition Roasting.
