What influences the taste of wine (except of variety of vines used)?

Although there are some disputes about this, most scientists and wine makers believe that environmental factors have a great deal to do with the way a wine ends up tasting.  (I am assuming you mean factors that affect the grapes and thereby affect the wine.)

Some of the factors that they think are important include:

  • The chemical composition of the soil
  • How much rain the growing area gets
  • How well the soil drains and therefore how wet or dry it tends to be
  • The amount of sunlight that the grape vines receive
  • The temperature variations during the growing season.

In addition to the elements mentioned previously, there is a specific "anatomy" in the wine that provides the flavor:

Acidity level in the grape as it grows from berry to fruit

Skin cell of the grape (provides the bouquet or aroma you first smell)

Amount of glycerol (which makes the wine smooth) in the drink

The bacterial secondary fermentation that changes malic acid into lactic acid (the more acid, the drier the wine)

Age of the oak barrel

Amount of added sugar and amount of alcohol

Hope this helps!

Winos unite!

Mainly enviornmental factors are responsible for determinig the taste of wine,though there are several other factors also.These are as follows:

1.Conditions of soil

2.Condition of climate/weather

3.Varities of grapes like red, white or black

4.The aging process of wine

5.viticulture and vinification

German researchers at the Johannes Gutenberg University Mainz Institute of Psychology have recently determined that the taste of wine can be significantly altered by serving it under different lighting. In other words, it would appear that the room the wine is tested in also plays a role in determining how a person experiences the beverage's taste.
