White wine is made from white or black grapes (but always with white flesh; the grapes with coloured flesh are called Teinturier, meaning coloured juice). Once harvested, the grapes are pressed, and only the juice, called wort, is extracted. The wort is put into tanks for fermentation where sugar is transformed into alcohol by yeast present on ...

Blending The mixing of two or more different parcels of wine together by winemakers to produce a consistent finished wine that is ready for bottling.
Red wine – A still wine with red to purple hues created by grape skin pigments, made from dark-colored grapes; Rosé – Rosé is a style of wine that is made by juicing red grapes and allowing them to macerate for a short period to give the juice a pinkish hue. The maceration step only lasts two to three days and after that, the skins are ...
The natural occurrence of fermentation means it was probably first observed long ago by humans. [3] The earliest uses of the word "fermentation" in relation to winemaking was in reference to the apparent "boiling" within the must that came from the anaerobic reaction of the yeast to the sugars in the grape juice and the release of carbon dioxide.
White wine can be made from any colour of grape as the skin is separated from the juice during fermentation. A white wine made from a very dark grape may appear pink or 'blush'. A form of Rosé is called Blanc de Noirs where the juice of red grapes is allowed contact with the skins for a very short time (usually only a couple of hours).
The grape originated in France, in the regions of Bordeaux and the Loire Valley. [10] Plantings in California, Australia, Chile and South Africa are also extensive, and Sauvignon blanc is steadily increasing in popularity as white wine drinkers seek alternatives to Chardonnay. [citation needed] The grape can also be found in Italy and Central ...
To make white wine, grapes are pressed quickly with the juice immediately drained away from the grape skins. The grapes used are typically white grape varieties, though red grapes may be used if the winemaker is careful not to let the skin stain the wort during the separation of the pulp-juice.
The fruit is a berry, known as a grape that is ovoid or globular, dark blue or greenish, usually 2-locular with 5 seeds; in the wild species it is 6 mm (0.24 in) diameter and ripens dark purple to blackish with a pale wax bloom; in cultivated plants it is usually much larger, up to 3 cm (1.2 in) long, and can be green, red, or purple (black).
