Apple cider is the name used in the United States and parts of Canada for an unfiltered, unsweetened, non-alcoholic beverage made from apples. Apple cider is easy and inexpensive to produce. It may be opaque due to fine apple particles in suspension and may be tangier than conventional filtered apple juice, depending on the apples used. This untreated cider is a seasonally produced drink of limited shelf-life that is typically available only in fall, although it is sometimes frozen for use throughout the year. It is traditionally served on the Halloween, Thanksgiving, Christmas and various New Year's Eve holidays, sometimes heated and mulled. It is the official state beverage of New Hampshire.
