Almost all wine grapes have white or clear juice. It is the wine-making process that determines whether the wine is red or white. While the wine-making process also controls sweetness and other taste characteristics, for the most part it is the grape variety that determines the basic characteristics of the wine. So, while it is possible to produce a sweet, white Zinfandel, most wines made from the Zinfandel grape are dark red, dry wines.
The chart below attempts to show the basic characteristics of wines made from eight of the most popular grape varieties. Before anyone raises their hand to complain, I admit without reservation that this chart is imperfect. However, I believe that it is sufficiently representative of these wines that it will be useful to the casual wine drinker.

Each of these grapes has distinctive taste and aroma characteristics. As with the chart above, the chart below is not a perfect representation, but it should serve to help the casual wine drinker understand the basic differences between these varieties.
Cabernet Sauvignon | Distinctive black currant flavor with a hint of mint and cedar. Ranges from medium bodied to full bodied; dry and tannic. |
| Zinfandel | Has a unique flavor, intense peppery fruitiness and a vibrant color; deliciously dry. |
| Merlot | Medium- to Full-bodied, less tannic than Cabernet, dry, black cherry, red and ripe summer fruits. |
| Syrah/Shiraz | Intense, with deep violet, nearly black color, chewy texture and richness, with aromas that tend to be more spicy than they are fruity. |
Pinot Noir | Medium- to Light-bodied, earthy, hint of herbs, aromas of red fruit cherries, game, licorice, smoke and earth. |
Sauvignon Blanc | Sharp, tangy, gooseberry is the predominant flavor, undertones of grass, nettles, elderflower and asparagus; dry and acidic. |
Chardonnay | Buttery, lemon flavors, sometimes nutty, often with a strong hint of tropical fruit. |
Pinot Grigio | Delicately fragrant and mildly floral with lightly lemon-citrus flavors. Can be tangy and light or rich, round and full bodied. |
Riesling | Aromatic, displaying flowery, almost perfumed, aromas of peach, appricot and/or apples, as well as high acidity. |
