BEER CONCENTRATE

摘要

The present invention concerns a method for preparing beer or cider concentrate comprising alcohol and volatile components of beer or cider flavour, and further beer or cider prepared therefrom. In particular, the invention concerns a two-step concentration method wherein the first step involves a high efficiency nanofiltration that results in a highly concentrated retentate and a aqueous permeate fraction comprising alcohol and volatile flavour components, and wherein the second step involves removing water from said permeate fraction to obtain a highly concentrated alcohol solution also comprising volatile flavour components, which is then combined with the retentate from the first step to a final high-alcohol and flavour beer or cider concentrate.
