Timing: We recommend a sample roast be 8-10 minutes (SCAA recommends 9-12 but we think 12 results in baked coffees when sample roasting). Go longer than that and you risk destroying the fruit or other notes in the coffee (enzymatics).
What is sample roasting?

When it comes to temperature, roasting requires a higher oven temperature of above 400°F for the cooking process, while baking takes place at lower oven temperatures around 375°F and below.
What are three methods of roasting?
- Spit Roasting. This is the traditional use of the term roasting and is only applicable to cooking meats
- Pot Roasting (Poêle’) Pot roasting uses a cooking utensil with a fight fitting lid
- Oven Roasting. Food is cooked in an oven by dry heat at quite high temperatures

What are the suitable temperature ranges for roasting?
Roasting is a cooking method that uses dry heat where hot air covers the food, cooking it evenly on all sides with temperatures of at least 150 °C (300 °F) from an open flame, oven, or other heat source. Roasting can enhance the flavor through caramelization and Maillard browning on the surface of the food.
What is post-roast coffee?
Post-roast blending means mixing the coffees after roasting each individually One reason to do this is to retain control of the roast level of each component. Roast, of course, also adds a whole other element to the flavor possibilities, and is used to pull out or obfuscate particular notes in the profile.
How do you cool coffee beans after roasting?

What is reduction roasting?
Reduction roasting is the removal of oxygen from a component of an ore, usually through the use of Carbon Monoxide (CO) The CO is typically supplied by mixing a carbonaceous material such as coke or coal with the ore, or by feeding it separately.
What is the difference between calculation and roasting?
Roasting involves heating of ore lower than its melting point in the presence of air or oxygen. Calcination involves thermal decomposition of carbonate ores.
How is a roast profile determined?
The roast profile is defined by temperature and roasting time Central components are temperature rise (when / how intense do i heat the beans) and reduction of roast temperature over time. This roast profile varies depending on the type of beans used and leads to different taste characteristics.
What is a roasting profile?
A roast profile is a set of parameters that define how a coffee should be, or has been, roasted Most roasters are fitted with a probe to measure the temperature of the beans in the drum, a probe to measure the exhaust gas, and an adjustable heat input.
How do you read a roast profile?
The yellow band indicates the second phase; 4:04 in duration or 35.7% of the entire roast. The brown band indicates the third phase; 2:14 in duration or 19.6% of the entire roast. Often a profile can indicate control changes made by the operator.

What is a good coffee cupping score?
The most important thing that the coffee cupping process tells us is that going from 80 to 90 coffee quality score is not a linear progression. Coffee that scores closer to 80 points is really good but can contain many more faults than the sample that enters the 90+ hall of fame.
