As a result, natural raw cider is a specialty seasonal beverage, produced on-site at orchards and small rural mills in apple growing areas and sold there, at farmers markets, and some juice bars.

Frequently blends of heirloom varieties such as Winesap, once among the most sought-after cider apples for its tangy flavor, are used. The US government requires that unpasteurized cider and juice have a warning label on the bottle.
