An improved system for providing an individually customized fresh brewed coffee beverage on demand by a consumer, in a wide range of variety and strength. Said brewing system for making relatively large quantities of fresh brewed coffee beverages (in particular, customized as to desired variety, body, character and/or strengths), as chosen by multiple individual consumers just prior to their consumption. Said system is easy to use by the consumer or other individual (e.g., restaurant wait staff) obtaining the customized beverage. Further, maintenance of the equipment requires only a small amount of personal attention by the owner/operator of the equipment. A general object of the present invention is to utilize “delayed dilution” of a concentrated extract to provide a beverage brewing system which immediately (upon customer selection) provides selective dilution (based on individual consumer's selections) of a fresh-brewed coffee extract after the extract has been allowed to brew and held as an extract before dilution.

Typical known methods for producing large quantities of concentrated extracts from solid raw materials such as ground, roasted coffee are not ideally suited to producing high quality coffee extracts that are rich in flavor and fragrance, and which maintain the varietal characteristics of the roasted coffee from which they are produced. The current invention provides filtration methods for producing such high quality concentrated extracts from more dilute extracts via solvent removal. The invention provides methods that have sufficient flexibility and scalability to be used for a wide variety of applications, including for producing industrial-scale quantities of extracts for the food and beverage industry. The invention provides methods and apparatus that can produce highly concentrated, “gourmet quality” extracts for use as flavoring agents, beverage concentrates, and fragrances.
