The main attractive features of the iRoast are:

• the machine easily roasts a full 130 to 150 grams of coffee, twice as much as the old Precision model
• the roast is very even in color
• there is a timer and thermometer built into the unit - you can display these details through the front LCD display panel
• programmable roast profiles
• The machine uses varying air flow and constant heat to control the way the coffee roasts.
