Roasted Coffee Beans

Roasting coffee beans is considered an art, as the roaster needs to determine when the process has brought the beans to their peak of flavor. Roastmasters often prefer to follow a "recipe" or "roast profile" to highlight certain flavor characteristics.

Coffee roasters use names for the various degrees of roast, such as Cinnamon Roast, Vienna Roast, American Roast, City Roast and French Roast, for the internal bean temperatures found during roasting.

But terms used to describe this process are not uniform, so you can not always count on them to tell you what your brew will taste like. Unless you have decided on the roast type, the best way to know what you like is to sample the various roasting options available.

Raw Green Coffee

Defects found in raw green coffee beans can be anything from unripened beans, to broken or discolored beans, to stones, twigs, or any foreign matter. Higher quality coffee is more carefully sorted to remove all of these defects. The greater the number of defects found in a lot of coffee, the lower the grade.

At this yellow stage the moisture content in the coffee beans begins to be released from the coffee and usually you will see steam arising from the roast. By now the humid grassy smell should normally be in the surrounding air. This is a very light roast level, immediately before first crack. Light brown, toasted grain flavors with sharp acidic tones, almost tea-like in character.

City Roast Coffee

Medium brown City Roast is common for most specialty coffee. It is Good for tasting the varietal character of a bean. City Roast coffee has completed the First Crack, and has been allowed to brown up slightly, but the Second Crack has not sounded yet.

Vienna Roast Coffee

Vienna Roast is characterized by small spots of oil on the bean's surfaces and a lightly deeper color than American Roast. This oil comes from within the coffee bean, is brought to the surface due to prolonged roasting time. The greater presence of such oil is what gives dark roasted coffee its distinguishable taste.

French Roast Coffee

French roasted beans are darker than Vienna roast and a bit oily with a hint of smokiness. Unlike the Italian roasted coffee beans that are black to the point of being carbonized, their flavor is extremely smoky and oily. French Roast creates a deep heavy flavor, some of the more subtle flavors of coffee will be hidden by the dark roasted smokeyness.

Spanish Roast Coffee

Extremely dark brown in color, nearly black and very shiny appearance with thinner body that is very charcoal, tar toned and flat. At this point the coffee's flavor-contributing compounds are very much degraded, the coffee's cellular matrix is completely ruined and the soluble solid content is diminished. The cup will taste absolutely "thin"

Coffee Cherry

The coffee cherry matures for about 5-6 months on the branch! During this period it is susceptible to damage from weather, rain (or lack thereof), hail, insect damage, etc. The cherry must be ripe when picked, which is why all quality coffee is harvested by hand because a branch contains ripe and unripe fruit simultaneously so hand picking is unavoidable

Why Outsource to OEM Manufacturer?

There are many reasons why companies outsource their roast coffee production to OEM manufacturers. Mainly because they can save on capital costs for they do not have to pay for a facility and the equipment needed for production. They can also save on labor costs such as wages, training and benefits.


The coffee roasting process follows coffee processing and precedes coffee brewing. It consists essentially of sorting, roasting, cooling, and packaging but can also include grinding in larger scale roasting houses. In larger operations, bags of green coffee beans are hand or machine-opened, dumped into a hopper, and screened to remove debris.


The green beans are then weighed and transferred by belt or pneumatic conveyor to storage hoppers. From the storage hoppers, the green beans are conveyed to the roaster. Roasters and the beans are roasted for a period of time ranging from 3 to 30 minutes and according to the specific roast profile of the clients.
