How wine is made?


The other day looking at the program How they Do it?? In Discovery Channel I thought that is interesting how many things that we normally use are so complete and complicated in her frabication so I searched and readed about wine making process and there is:
Before wine is removed or harvested from the vineyar, the amount of sugar in the grape must be measure. After the sugar is measured, the wine maker can estimate the alcohol concentration of the finished product.
The grapes are crushed to make the juice accesible to the yeast. Crushed grapes are called the must. The must is made up for 80% of juice, 16% skins (wine pigment), and 4% seeds. Controlling the amount of contact achieved between the juice, skins, and seeds is critical to the flavor and color of the wine.
Pressing is done to separate the skins, seeds, and any other non-juice item from the juice. There are different types of presses used in the winery industry. Some of the popular ones are the screw membrane/ bladder, moving head, and basket presses. Fermentation is initiated by adding yeast to the juice or must. The fermentation procces is regulated closely by managing the temperatura.
The wine is then aged by using barrels. Barrel aging is typicallyused for red wines and adds vanill, spicy, and sometimes smoky flavors to the wine. Wine is then filtered to further clarify and stabilize it…
