Cider
Cider is an ancient beverage. No-one knows when or where it was first made, because the native distribution of its principal component, the apple, is so widespread, from the Near East to Northwestern Europe. In the cider market, ciders can be broken down into two main styles, standard and specialty. The first group consists of modern ciders and heritage ciders. Modern ciders are produced from culinary apples such as Gala. Heritage ciders are produced from heritage, cider specific, crab or wild apples, like Golden Russet. Historically, cider was made from the only resources available to make it, so style wasn't a large factor when considering the production process. Apples were historically confined to the cooler climates of Western Europe and Britain where civilization was slow to develop record keeping. Cider was first made from crab apples, ancestors of the bittersweet and bittersharp apples used by today's English cider makers.
Apple cider
While some states specify a difference between apple juice and cider, the distinction is not well established across the U.S. Massachusetts makes an attempt to at least differentiate "fresh" cider and processed apple juice: according to its Department of Agricultural Resources, "apple juice and apple cider are both fruit beverages made from apples, but there is a difference between the two. Fresh cider is raw apple juice that has not undergone a filtration process to remove coarse particles of pulp or sediment. Apple juice is juice that has been filtered to remove solids and pasteurized so that it will stay fresh longer. Vacuum sealing and additional filtering extend the shelf life of the juice." This still leaves unfiltered apple juice that is no longer raw in a gray area, presumably cider but not labeled as such. The addition of sweeteners or reconstitution from concentrate are left even grayer.
