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. 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 ...
In this process, solvent is added to moistened green coffee beans to extract most of the caffeine from the beans. After the beans are removed from the solvent, they are steam-stripped to remove any residual solvent. The caffeine is then recovered from the solvent, and the solvent is re-used. The Swiss Water Process is also used for decaffeination.
Roasted coffee beans. The next step in the process is the roasting of green coffee. Coffee is usually sold in a roasted state, and with rare exceptions, such as infusions from green coffee beans, [98] coffee is roasted before it is consumed. It can be sold roasted by the supplier, or it can be home roasted. [99]
Coffee production begins when the seeds of the Coffea plant's fruits (coffee cherries) are separated to produce unroasted green coffee beans. The beans are roasted and then ground into fine particles. Coffee is brewed from the ground roasted beans, which are typically steeped in hot water before being filtered out.
Green coffee extract is an extract of unroasted, green coffee beans. It is used in the Swiss water process for decaffeinating coffee. It has also been used as a weight-loss supplement and as an ingredient in other weight-loss products, although there is insufficient clinical evidence that it is effective or safe for such uses.

The production of "Guglielmo Caffè", [5] begins with the "green coffee" and has four stages. 1st stage (Introduction of the green coffee): The coffee, from the hopper of the store, is aspirated pneumatically and cleaned from impurities in a separating cyclone. Also pneumatically, it is sent in a silo with ten cells and stored until the next stage.
In March 2012, Starbucks began selling a line of iced Starbucks Refresher beverages that contain a green coffee extract. The beverages are fruit flavored and contain caffeine but advertised as having no coffee flavor. Starbucks's green coffee extraction process involves soaking the beans in water. [131]
Coffee bean storage is a broad term describing the packaging and preservation of coffee beans throughout the process from harvesting to brewing. Although the term is applicable to many phases of this process, it is typically applied to ideal home storage for maximum consumer coffee enjoyment.
