This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,856,964.

Background and Problem Solved

The original method of producing a flash brewed coffee concentrate, as described in the original patent, has limitations in terms of flavor profile, bitterness, shelf-life, and customization options. The present invention addresses these limitations by introducing novel formulations, systems, and methods that improve the overall quality and versatility of the flash brewed coffee concentrate.

Novelty and Inventive Step

The new invention's novelty lies in the introduction of novel formulations and systems that improve the flavor profile, reduce bitterness, extend shelf-life, and enable customization of the flash brewed coffee concentrate. The inventive step is in the combination of these features, which overcome the limitations of the original method and provide a more versatile and high-quality product.

Alternative Embodiments and Variations

Alternative embodiments of the invention could include variations in the brewing unit, mixing unit, and temperature control system. Additionally, different formulations of the concentrated coffee extract could be developed to cater to specific flavor profiles or regional preferences.

Potential Commercial Applications and Market

The enhanced flash brewed coffee concentrate production methods and systems have significant commercial potential in the coffee industry, particularly in the cold brew coffee market. The invention's ability to provide customizable flavor profiles, reduced bitterness, and extended shelf-life makes it an attractive solution for coffee manufacturers, cafes, and restaurants seeking to differentiate their products and improve customer satisfaction.
