clear juice

In food processing, clear juice is obtained by separating the liquid from solid components of fruits. For white grapes, this typically involves immediate separation from skins and seeds after crushing to preserve a light color.1

Two primary methods are used for juice separation:
* Free-run juice: This is the juice that drains naturally from crushed grapes before pressing.1
* Pressing: Crushed grapes are placed in a press to extract the remaining juice. Various types of presses exist, including basket presses and continuous screw-type presses.1

For red wines, skins, seeds, and juice are fermented together, simplifying juice separation afterward. Fruit juices, in general, are processed through washing, extraction, clarification (often using filtration), and preservation methods like pasteurization or concentration.12
