There are different juice types that says on label
- 100% juice
- Not from concentrate
- From concentrate
- 96% juice (they are usually cheaper).
What is the difference between them?
Fruit contains lots of water. When you take a piece of fruit at home and press it, you end up with sugars, vitamins and other solids dissolved in water. Let's assume that 100 g of just-pressed juice has X g of water and 100-X g of juice.
A manufacturer who sells juice can do several things.
100% juice, not from concentrate, and will often be labelled as "contains pulp" for citrus juices, or "naturally cloudy" for apple juice.
100% juice, not from concentrate, sold as "clear" juice.
100% juice from concentrate. The advantage from the manufacturer: he pays per weight for shipping between the juicing factory (which can be somewhere in the tropics where fruit is cheap) and the packaging plant (which is close to where the customer lives). Not shipping tons of water saves lots of costs, and concentrate is less perishable than non-packaged juice.
50% fruit juice drink. Most customers expect a fruit juice to be sweet and slightly sour, so the manufacturer adds not just water, but water with sugar and acid in it (mostly citric acid). A 96% juice would be if the manufacturer adds only 4 g of water to 96 g of juice.
