The sugars in grapes and their role in wine making
Sugars are an important component in grapes and play a significant role in wine making. There are different types of sugars found in grapes, including fructose, glucose, and sucrose. The sugar content of a grape affects the taste of the wine, as well as the alcohol content.
The fructose and glucose in grapes are responsible for the sweetness of wine. The higher the sugar content, the sweeter the wine will be. The sugar content also affects the alcohol content of wine. The more sugar present, the higher the alcohol content will be.
Sucrose is a sugar that is not as fermentable as fructose and glucose. This means that it does not contribute to the alcohol content of wine. However, it does affect the body, mouthfeel, and flavor of wine.
The sugar content of grapes is measured in degrees Brix (°Bx). The °Bx is a measure of the percentage of sugar in a grape. For example, a grape with a sugar content of 20°Bx will have twice as much sugar as a grape with a sugar content of 10°Bx.
Grapes with a higher sugar content are typically used to make sweeter wines, such as dessert wines. Grapes with a lower sugar content are typically used to make dry wines.
The sugar content of grapes can be affected by many factors, such as the variety of grape, the climate, and the ripeness of the grape. The sugar content can also be affected by the winemaking process. For example, adding sugar during the fermentation process can increase the sugar content of wine.
The type of yeast used during fermentation can also affect the sugar content of wine. For example, yeasts that are more efficient at fermenting sugars can result in a wine with a lower sugar content.

How to make white wine from grapes
Wine is made by fermentation of grape juice. Yeast consumes the sugar in the grape juice and produces alcohol and carbon dioxide. The carbon dioxide is lost to the atmosphere, and the alcohol becomes the wine.
The first step in making wine is to crush the grapes and collect the juice. The crushed grapes, called must, are then placed in a fermentation vessel. A fermentation vessel is usually made of glass or stainless steel, and has a capacity of 5 to 30 gallons (19 to 114 liters).
Yeast is added to the must, and the mixture is allowed to ferment. The temperature of the must is carefully monitored, as too high of a temperature will kill the yeast, and too low of a temperature will produce a wine that is too acidic.
The fermentation process takes about one to two weeks. During this time, the yeast consumes the sugar in the grape juice and produces alcohol and carbon dioxide. The carbon dioxide is lost to the atmosphere, and the alcohol becomes the wine.
After fermentation is complete, the wine is transferred to a container for storage. The wine can be stored in bottles or in barrels. Wine that is going to be aged for a long time is often stored in barrels.
White wine is made from green grapes that have not been allowed to ripen for very long. The green grapes have a higher acidity than ripe grapes, and this gives the white wine its characteristic flavor.
The steps for making white wine are the same as for making red wine, with a few exceptions. The grape must is usually cooled before fermentation, to preserve the delicate flavor of the grape juice. The fermentation process is also shorter, as white wine does not need to be aged for as long as red wine.
After fermentation, the wine is usually filtered to remove any sediment. It is then ready to be bottled or stored in barrels.
