why is white wine white and red wine red yet it is made from the same grapes.?
Posted in: Grape Growing by admin on June 20, 2010
White wines are almost always made from white grapes, although they can be made from black grapes, since the juice in most black grapes is clear. When white wine is made, the skins of the grapes are separated from the juice when they are put into a crushing machine.
Red wine is usually made from red or black grapes, although all the kinds of grapes usually have a clear juice. The process of making red wine is different from the one of making white wine. After the grapes have been in the crushing machine, the red grapes with their skins and everything sit in a fermentation vat for a period of time, typically about one to two weeks. . The skins tend to rise to the surface of the mixture and form a layer on top. The winemaker frequently mixes this layer back into the fermenting juice (which is called must). After fermentation is over, the new wine is taken from the vat.
The main difference between red and white wines is the amount of tannins they have. Since tannins largely come from the grape skins, red wines have more of them than white wines.
Hope this helps.

They are not made from the same grapes. White wine comes from grapes with yellowish-green skin and red wine comes from grapes with reddish/purple skin. For example, "Chardonnay" is the name of a type of grape used to make white wine, while "Cabernet Sauvignon" is a red wine grape. More to the point, red grapes still have clear juice, like white wine grapes. The color in red wine comes from the red grape skins being crushed with the juice during the wine making process.
Five thumbs down? Huh?!?!? FOR WHAT?

This is because of the mixtures that they add in to the process of making the wine.

There are different types of grapes. Some have red skins, such as merlot, and malbec, others have white or grey skins such as pinot gris and chardonnay.
You can make white wine from just about any of the grapes by pressing with little contact to the skins. The best example might be a "blanc de noir" sparkling wine, where pinot noir (a red grape) is used to make a white wine, but also rose’ wines are made from red grapes with very little skin contact, such as white zinfandel.
Most red wines are made with primarily red grapes and the juice is allowed to have contact with the skins to extract the pigments. This is how most all red wine is made.

Grapes vary in color from white-ish translucent to almost black. The type of wine you are drinking is the type of grape used. Merlot, Chardonnay, Pinot Noir, etc. are grape varieties. Most grape’s juices are clear or semi-clear (white wine colorish).
White wines are made by pressing the grapes, and then not letting the juices come in contact with the pomace (stems, skins, etc.).
Red wines are made by using darker colored grapes, and instead of a pressing to separate the juice from the skins, you crush the grapes in an open vat and allow the dark colored skin to stay in the juice during primary fermentation. This causes some of the color from the skins to ‘bleed’ into the juice and turn it a darker color.

First, they are not the same grapes. They are made the same way except the SKINS of the grapes are left with the fermenting juice in red wine, and filtered out in white wine, and the skins are left on for a brief time in Rose’ or Blush.

RED WINE IS MADE FROM RED DARK GRAPES AND WHITE WINE IS MADE FROM WHITE OR GREEN GRAPES, DUH.
