Varieties
The key to understanding wine is to familiarize your self with vinifera varieties (Cabernet Sauvignon, Pinot Noir, Chardonnay, etc.) and how each variety has certain unique characteristics in color, aroma and taste. Some wines are produced using only one grape variety and this style is referred to as a varietal or single varietal wine, if two or more varieties are used, like Bordeaux wines, the wine is referred to as a blend.
Wine grapes or varieties are categorized into two groups, white grapes, which are used for making white wine and black grapes, which are used mainly for reds due to their higher tannin content and color pigmentation. What distinguishes one variety from another is color, skin thickness, tannin, sugar to water ratio, acidity, and grape performance (yield, late budding, etc.).
