Question

How do they get wine and grape juice out of grapes?

Answer 1

YOu press it.  IN the old days, you get someone to step on the grapes and drain the juice.

Answer 2

The juice is pressed from the grapes, and separated from the skins. Occasionally, the juice is left in contact with the skins to give the juice either a more vivid colour or more complex flavours. After this the juice is separated into vats, where it is allowed to ferment.

Answer 3

You press the juice out and add a variety of items, like yeast

Answer 4

As said, the grapes are pressed.  To add a little for you, whites are pressed immediately, reds are crushed (broken) and destemmed, fermented, and then pressed.  Fermenting with the skins creates the red color.  Red wine grapes do not have red juice (except for a couple minor varieties).  If you press red grapes before fermenting, you get blush wines like white Zin.

The most common modern press is a bladder press.  It is a big cylinder on its side that is perforated with thousands of tiny holes.  Inside is a big balloon made of a heavy rubber.  When the press is filled with grapes, so juice flows naturally out of the grapes without pressing.  This is called "free run" juice and is usually the highest quality.  Then, the balloon is inflated with compressed air to squeez the fruit against the walls of the cylinder.  When the flow slows down, the balloon deflates, the cylinder rotates to redistribute the grapes, and the balloon is inflated again to a higher pressure to extract more juice.  This is done two or three times with each "press cut" yielding a lower quality juice than the previous.  Some wineries blend them all, some keep them separate.  This is often where a winery will first make the distinction between their regular bottling, and a "reserve."

Answer 6

Its pressed in giant vats and seperated from the skins and pips (seeds). Wine is feremented grape juice. Grape juice and wine aren't usually made in the same place though.

Answer 7

Commercially the wine maker has large equipment that destems and crushes the grapes to release the juice. For pure juice the grapes are either pressed or centrifuged (spun).

Most winemakers DO destem & crush their own grape berries.

Once the grapes have been crushed the juice and in the case of red wine juice + skins are pumped to a fermentation tank. In  the tank yeast is added and the juice is converted into wine.
