Apple juice is a non-alcoholic fruit juice pressed from crushed apples.
Pear juice is the closest in weight and softness. White grape is sweeter and less recognizable, which is useful when the apple was structural rather than a flavor. Cloudy and clear swap freely as long as you know which one the drink was built for.
Apple cider (North American)
Unfiltered cloudy pressed juice: the same fruit, just with the pulp left in. The drink comes out heavier and hazier — visible in a clear cocktail, arguably a gain in a shaken one. Watch for British cider, though: that one is fermented and alcoholic.
Apple juice from concentrate
Reconstituted with water after the juice was reduced, and it is sweeter and flatter; the aroma that boiled off is exactly the part a drink was using.
Fresh juice browns within the hour and is properly brown by the next day, so press to order or slow it with lemon. Bottled keeps to its date and wants the fridge once open.
