Aged beer, also known as 'cellar beer' or 'vintage beer', is a type of beer that has been aged for a period of time in order to enhance its flavor and complexity. LAGER is a type of beer that is brewed using bottom-fermenting yeast and is stored at cold temperatures for several weeks or months before it is served. It is usually light in color and has a mild, malty flavor. Aged LAGER is a type of LAGER that has been aged for an extended period of time, usually several months or even years. This aging process allows the beer to develop a more complex flavor profile and can result in a smoother, mellower taste.
