How is wine made?
Please have a look at this video, which offers a comprehensive explanation of how white and red
wines are made (it lasts only 5 mins): http://video.about.com/wine/See-How-Wine-IsMade.htm
How is red wine made?
1 The winemaker checks the sugar, acidity and tannin levels of the grapes.
2 The grapes are harvested…
2a and brought to the winery.
3 The grapes are de-stemmed and crushed.
4 They are pumped into a press, and the juice is pressed. The juice and skins are pumped into
vats. See the video (4). http://www.youtube.com/watch?v=XtsIGqRto6g
6 Yeast is added.
7 The juice and skins ferment in the vats. They need to be frequently mixed. The temperature of
the vats may be regulated to maintain the fermentation.
8 After a few days, the skins are removed.
10 In fermentation sugars are converted by yeast into alcohol. In the process CO2 and heat are
produced. When the fermentation is finished, sediment falls to the bottom of the vat. This is
pumped away.
11 Wines mature in the vats, or in oak casks. They undergo a second fermentation, called
malolactic fermentation. In malolactic fermentation, lactic acid bacteria convert malic acid into
lactic acid.
12 At various points during the production process, wine can be filtered.
13 Wines are bottled. They may mature further in the bottle before being sold.
