Cider apple
Cider is made in several countries and can be made from any apples. Historically the flavours preferred and varieties used to produce cider have varied by region. Many of the most traditional apple varieties used for ciders come from or are derived from those from Devon, Somerset and Herefordshire in England, Normandy in France, and Asturias in Spain, and these areas are considered to have their own broad cider styles although the many exceptions make this more of a historic footnote. Normandy cider is usually naturally carbonated and clear: Asturian cider apple varieties are mainly 'sharps' or mild 'bittersweets', producing a mildly acidic cider which is customarily served by being poured from height into the glass to oxygenate it.
Apple cider
It is the liquid extracted from an apple and all its components, that is then boiled to concentration. The liquid can be extracted from the apple itself, the apple core, the trimmings from apples, or apple culls. Once pressed mainly at farmsteads and local mills, apple cider is easy and inexpensive to make. It is typically opaque due to fine apple particles in suspension and generally tangier than commercial filtered apple juice, but this depends on the variety of apples used. Cider is typically pasteurized to kill bacteria and extend its shelf life, but untreated cider is common. In either form, apple cider is seasonally produced in autumn. It is traditionally served on the Halloween, Thanksgiving, Christmas, and various New Year's Eve holidays, sometimes heated and mulled.
