Abstract: Methods, devices, and systems are provided for controlling off-flavors of low-alcohol and nonalcoholic beer. The formation of Strecker aldehydes is limited during the processing and subsequent storage of low-alcohol or nonalcoholic beer. Limiting the formation of Strecker aldehydes provides an improved sensory perception and taste through a reduction in worry flavors.

Abstract: Methods and systems are provided that process beer into an oxygen-stable long shelf life spirit. The process includes introducing oxygen into the beer and heating the beer to a temperature within a predetermined temperature range and allowing the beer to age at the predetermined temperature for a number of days. During this aging process, the beer transforms into an oxidized beer spirit. The beer spirit is cooled to room temperature and is then chilled for a period of time to separate unwanted precipitate and byproducts from the beer spirit. After the beer spirit is chilled, the beer spirit is forced through at least one filter to remove precipitate and provide a clear and filtered spirit having a complex taste and aroma profile.
