Additional Tips:

*Roasted Beans remain at peak flavor for about 2 weeks. Placing them into a vacuum container can extend this time. Refrigeration does not extend their life.

*Ground Beans remain fresh for only 2 days.

*Flavors may be safely added after roasting. Place the roasted beans into a mixing bowl to add flavorings. Never place liquids into the roasting pot!

Lower Elevation = Higher Caffeine
Robustas tend to be less expensive, more readily available, but higher in caffeine - the result of growing at a lower elevation. Arabicas are coffee beans grown between 2000 feet and 6500 feet. This higher elevation results in a lower caffeine content since the plant no longer needs its natural pesticide. Arabicas make a cleaner, smoother cup of coffee.

** In the i-Roast, Preset 1 is set at 450 F for 10 minutes and was made more for former Precision Roaster users. Many of our customers still enjoy our Precision, so for that reason, we set Preset 1 to the Precision.
