Abstract
Provided are surprisingly effective methods for producing uniform, cold-brew beverages (e.g., coffee, tea, fruit juice/extract, vegetable juice/extract, etc.) having an extended shelf-life, comprising: use of non-oxygen gas mixtures comprising hydrogen (to reduce or eliminate total packaged oxygen (TPO)), use of pressure/vacuum ports in brewing and/or conditioning chambers to provide chambered vacuum and/or pressure to enhance oxygen elimination, use of continuous mixing/agitation during the final conditioning phase to provide for even particulate suspension, use of a two-phase filtration system to provide for uniform tailoring of the amount and/or size of undissolved solids, and use of jacketed brewing and/or conditioning chambers for enhanced control of temperature, extraction uniformity and conditioning. Cold-brew beverages prepared by the methods, and systems for making same are provided. Beverages prepared by any method and packaged in a container and exposed therein to a non-oxygen gas mixture comprising hydrogen, and methods for making same are provided.
