Description

METHOD FOR REFRESHING ROASTED COFFEE

FIELD OF USE

[0001] The present disclosure relates generally to devices, systems, and methods that refresh roasted coffee. More specifically, the present disclosure relates to refreshing previously roasted coffee using a heat source.

BACKGROUND

[0002] From the 1800’s to 1980s the typical coffee drinking consumer in the United States had access to a handful of mass-produced instant coffee or diner-type robusta batch brewed coffee served in restaurants or for home use. Very few specialty high end coffee bean roasting facilities existed that also featured an exclusive upscale, high priced coffee house setting for freshly roasted, freshly brewed, full bodied, strong flavored and robust arabica coffee drinks. The smell of freshly roasted coffee beans is the signature pleasure of visiting a coffee house that also does coffee roasting.

[0003] The whole coffee bean roasting process is a traditional, time-consuming, delicate, and technical process, which requires expensive roasting equipment that is installed within a specifically designed and regulated approved industrial food processing environment that provides for fire safety suppression system, heat exhaust, and ventilation equipment. This equipment is typically operated by specially trained whole coffee bean roasting masters. In sum, roasting green coffee beans to perfection is a delicate, time consuming, and dedicated process that is expensive and requires the use the specialized coffee roasting equipment.

[0004] For the past four decades there have been an explosion of European style coffee shops across the United States that has revolutionized the coffee drinking experience. Consumers now have access to both mass-marketed fresh brewed and fresh roasted coffee, single cup pour over coffee, and/or small batch exotic coffees that are strong, proprietary, and uniquely flavored. These specialty coffee shops have been able to capture significant and highly profitable sales away from the traditional coffee serving outlets, such as restaurants, fast food restaurants, convenience stores, and gas stations. Moreover, this trend has caused the entire coffee serving industry to raise the level of quality of coffee being served. Finally, the demand for great coffee is still growing and new products and flavors continue to hit the market. However, consumers are waking up to the fact that many of the specialty coffee shops are very expensive. Thus, there is a significant and growing market demand from traditional coffee serving retailers for better quality, flavor variety, unique, and fresh roasted gourmet coffee drink that have high profit margins, affordable prices, and can be provided via convenient and fast service.

[0005] There are several reasons for wanting to re-roast or freshen previously roasted coffee. Some of these reasons include, the desire for a darker roasted beans, the desire for the smell of fresh roasted coffee, or the desire to freshen stale coffee. It is generally accepted that once a coffee has been roasted, re-roasting it will not improve the flavor or freshness of the coffee. Specifically, prior to the method of the present disclosure, attempts to re-roast coffee were unsuccessful because once coffee beans have cooked and cooled, they could not be cooked or roasted further without diminishing or out-right ruining the flavor of the coffee. This is because roasting temperature profiles and sequences make a big difference in how the coffee ultimately tastes. Prior to the method of the present disclosure, re-roasting coffee would result in the coffee oils coming to the surface of the bean and being scorched by the re-roasting process.

[0006] Thus, there is a need for a method of using heat to refresh previously roasted coffee that not only does not diminish the taste of the resulting brewed coffee, but instead enhances the flavor and provides the great aroma that is provided by small batch specialty coffee roasting houses. The method of the present disclosure is such a method.

SUMMARY OF ILLUSTRATIVE EMBODIMENTS

[0007] To minimize the limitations in the cited references, and to minimize other limitations that will become apparent upon reading and understanding the illustrative embodiments, the present disclosure teaches a new and useful method for refreshing roasted coffee.

[0008] In one embodiment, the method of the present disclosure provides a flash re-roasted coffee that, when used, enhances ordinary coffee to have a rich aroma, freshness, and smooth taste and feel that is associated with coffees made by a professional roast master. The flash re-roasting method allows almost any coffee serving establishment to provide all consumers with easily accessible, price friendly, and consistently great coffee that tastes and smells like it was just roasted and freshly brewed.

[0009] In one embodiment, the method and system of the present disclosure provides a just roasted coffee smell, onsite roasted freshness, flavor variety, and enriched quality of freshly roasted and brewed coffee to any coffee serving facility has an oven or source of radiant heat.

[0010] The method and system of the present disclosure provides significant advantages because it can be used to enhance the flavor and quality of any type of pre-brewed and post-roasted coffee, including whole coffee beans, ground beans, and instant coffee.

[0011] In one embodiment, the method of the present disclosure may comprise the steps: providing pre-roasted coffee; providing water; optionally providing a flavoring; mixing the pre-roasted coffee, water, and (optionally) the flavoring; placing the mixture in a baking type container; covering the container (with a lid, foil, or the like); placing the baking type container in or near a source of heat (oven, conveyor oven, broiler (electric or flame), griddle, or grill); heating the baking container that contains the mixture for 15 seconds to 360 seconds at a temperature of 250 F to 600 F. Preferably, the mixture may be heated for 60 seconds to 180 seconds at 475 F. [0012] Any baking (heat/oven safe) container may be used such a tray, pan, aluminum pan/foil/pouch, sheet, or pot. Preferably the baking container used may be a metal tray or pan that is commonly used in food service kitchens and facilities. However, specialty pans and ceramic dishes may be used so long as they can withstand the heating process. Preferably, the trays used have short lips or sides to prevent the beans from escaping or falling off the tray. Preferably, the side or lip is not more than three inches (3”) deep.

[0013] In one embodiment, the roasted coffee may be whole roasted beans that are mixed with water and/or flavoring, heated via the method of the present disclosure, cooled, ground, and brewed. In another embodiment, the roasted coffee may be ground coffee that is mixed with water and/or flavoring, heated via the method of the present disclosure, cooled, and brewed. In another embodiment, the roasted coffee may be instant coffee that is mixed with water and/or flavoring, heated via the method of the present disclosure, cooled, and “brewed”.

[0014] Depending on the need, coffee type, coffee brewer size, and equipment, the coffee may preferably be approximately 4.5 ounces of ground, instant, or whole bean coffee to approximately 1.0 to 3.0 ounces of spring or distilled water. Optionally, approximately 0.5 to 2 ounces of a flavoring (preferably a natural flavoring) may be added.

[0015] Depending on the need, coffee type, coffee brewer size, and equipment, the heating time may vary. The type of heating device and temperature limitations may also vary the heating time. [0016] By combining the coffee with water (and a flavoring), the step of heating re-activates the natural oil in the coffee without causing a scorched or burnt taste. The heating step also causes the aroma of fresh roasted coffee to fill the restaurant or food service facility, which may have a profound effect on increasing coffee sales. [0017] The steps of removing the refreshed roasted coffee from the baking container and allowing it to cool further spreads the aroma to fill the food service facility in which the method is being practiced. Preferably, the cooling step is approximately 1 second to 120 seconds before brewing, but may be longer.

[0018] In one embodiment, the method of the present disclosure may be completed very quickly, wherein the heating time is approximately 100 seconds.

[0019] The method of the present disclosure is a way for a traditional coffee serving facility to compete with a specialty coffee house by providing superior coffee and the aroma of freshly roasted coffee beans all at an affordable price with no need to upgrade equipment. The heating step of the method may be used with many of the widely available and currently in use baking devices, ovens, convection ovens, high-speed ovens, programable ovens, combination ovens, and warming ovens.

[0020] Furthermore, there is no need for costly specialty labor (roast masters), specialized unique equipment (coffee roasters), or expensive buildouts (exhaust systems, fire safety systems, regulated systems and/or fire suppression systems). The method of the present disclosure may be used with any brand or type (arabica or robusta) of coffee. The method also allows for a convenient and easy way to create a just roasted flavored coffee that is consistent and tastes great.

[0021] Although not necessary, facilities that have programmable, high speed, convection, and rotary/conveyor ovens may be able to practice the method of the present disclosure in a very consistent way to ensure perfect refreshed coffee every time. Two examples of well suited ovens to be used with the method of the present disclosure are the Turbochef® Tornado® (which is a type of High Temperature Programable Ventless Impingement Type Convection Oven with Catalytic Converter, hereinafter referred to as a Programmable Convection Oven) and the Turbochef® 1618 (which is a type of High-Speed and High-Temperature Programable Ventless Impingement Type Rotary Belt Convection Oven with Catalytic Converter, hereinafter referred to as a Programable Conveyor Oven).

[0022] In addition to traditional radiant heating devices and ovens, microwave ovens may be used. As an example, when heating via a mid-power microwave oven, the coffee and water (and flavoring) are preferably heated for approximately 120 seconds to 240 seconds at 600 W or 1200 W (full power).

[0023] Other features and advantages are inherent in the method of refreshing roasted coffee that is claimed and disclosed will become apparent to those skilled in the art from the following detailed description and its accompanying drawings.
