The invention pertains to a novel method for enhancing clarity and reducing the acidity of brewed coffee beverages. By incorporating potassium bicarbonate into either 1) roasted coffee beans (whole or ground) or 2) instant coffee granules, or 3) by providing potassium bicarbonate mixed with a carrier which can be added directly to brewed coffee, the turbidity of the resulting brewed coffee is significantly decreased, thereby improving its visual appeal. Additionally, the acidity of the brewed coffee is lowered, making it more palatable and potentially alleviating gastrointestinal discomfort often associated with acidic beverages. The process allows for customization based on the desired strength of the coffee and the chosen brewing method. This innovation presents a promising solution to enhance the overall quality and consumer satisfaction of coffee products.

This disclosure provides a method of determining the brewing parameters for preparing a coffee beverage with a coffee brewing apparatus, comprising: receiving, at a sensing arrangement, a coffee product for brewing a coffee beverage; obtaining, with the sensing arrangement, a characteristic of the coffee product; using the characteristic to determine one or more brewing parameter for the coffee product and brewing a coffee beverage using the one or more brewing parameter.

The present invention describes new compositions of matter comprising (1) roasted coffee beans in either whole bean form or in ground form to which a formulation containing resveratrol and glycerin and/or specified additional additives have been added, (2) liquid beverages extracted at a pressure of less than 2000 bar from said roasted coffee beans or grounds to which a formulation containing resveratrol and glycerin and/or specified additional additives have been added; and (3) so-called instant coffee or soluble coffee prepared from roasted coffee beans to which a formulation containing resveratrol and glycerin and/or specified additional additives have been added, but in which a pulverized coffee component is specifically excluded. The formulation including glycerin leads to increased solubility and bioavailability of resveratrol. By adding a formulation containing resveratrol and glycerin to roasted coffee beans and/or instant coffee, consumers enjoy the health benefits of resveratrol in their coffee without drinking red wine.
