To make everything simple with will touch mostly on the wines that are made from grapes alone. These are categorized by several means, which include vinification methods, taste, and lastly vintage. Many unknowing wine drinkers wouldn't care about the subtle differences in these categories, after all, most people rely completely on the taste of the wine.
These wines have to abide by the highest levels, everything has to be exactly dead on, the type of grape, taste, and quality of the vintage must all conform to the best standards before any wine master will even think about having it as part of there collection.
Vinification
Vinification is the process by which grape juice is fermented into wine. The process of fermentation determines how the wine turns out and it is this quality that determines the price. The 1 mistake made by the early wine drinkers is that the juice from the grapes varies; this isn't the case as juice from either grape is colorless.
Taste
Most wines are described as dry, off-dry, fruity, or sweet. This is a direct result of the amount of sugar that is left over after the fermentation process has ended, Dry wine has very little sugar content, while a sweeter wine has higher sugar content.
