Chardonnay - Produces French white Burgundy and perhaps the most popular wines in the U.S. wine.
Chenin Blanc - The major grape planted in the French Loire valley. In the U.S., often used to make a light, fruity wine.
Gewurztraminer - Wine from this grape has a floral smell and the wine itself is often drunk with spicy foods. Gewurztraminer also makes a good "late harvest"sweet dessert wine. It is more common in Alsace, Italy, and the United States than in Germany and many "experts" say Alsace makes the best.
Riesling - Also, to me, producing a floral smelling sort of wine, it also makes a sort of light, fresh type of wine. Makes a great "late harvest" sweet dessert wine (for which it is especially known in Germany). Another viewpoint, it isn't so much floral as "minerally" with accents of fuel oil--not light and fresh, instead, lots of depth and complexity in something like a good German Riesling Spatlese or Alsatian Grand Cru.
Sauvignon Blanc - In the U.S., makes a crisp, light wine (sometimes with a "grassy" or "herbaceous" characteristic). It is a component (along with Semillon ) of the French dessert wine, Sauternes and the white wines of Bordeaux.
Semillon - As with many grapes, while grown elsewhere (such as California), Semillon is one of the major varieties grown in Bordeaux. Like Sauvignon Blanc is can often have a grassy (or herbaceous) note, but also may have notes of ripe figs. It may be drunk "dry", or "sweet", and as such, it is a component (along with Sauvignon Blanc ) of the French dessert wine, Sauternes and the white wines of Bordeaux.
