Unlike the Guide to White Wine Varietals Part 2, the following wines in Part 3 should be much more familiar. These wines are some the lightest, but contain higher acidity than many other white varietals.
Pinot Blanc – Best known as a varietal from Alsace, Pinot Blanc is also widely grown in Austria, Italy (Pinot Bianco), Germany (Weissburgunder), Eastern Europe, California, and Canada. Its characteristics vary considerably from country to country, but the wine is generally dry with a good level of alcohol. Light in color, Pinot Blanc is similar to unoaked Chardonnay, and can be confused for Chardonnay in the glass.
Pinot Gris – Closely related to Pinot Noir, it has a pinkish, light purple skin. As with Pinot Blanc, it is best known as an Alsatian grape and is classified there as a noble variety. It is grown in Austria and Germany, where it is known as Rulander and Grauerburgunder, as well as in Italy and the US where it is known as Pinot Grigio. These wines are normally dry with floral notes, and flavors of white peach and apricot. Alsatian styles tend to be spicier than their Italian counterparts which can have more of a minerality to them. US styles tend to be lighter and sweeter.
Rhine Riesling – The classic white grape from Germany, it produces very high quality Rhine and Mosel (German regions) wines, as well as top quality wines in Alsace, Austria, Australia, New Zealand, US, Chile, and South Africa. Rieslings grown in Germany and Austria usually display more of a mineral quality along with pear, green apple, peach, and honey coupled with good acidity. New World style Riesling may not be Rhine Riesling, and tend to be less complex. As Rieslings age, they develop a petrol characteristic.
Roussanne – A light aromatic wine, high in acidity, it is frequently blended with Marsanne for such wines as Hermitage Blanc and Chateauneuf du Pape Blanc – both of which are grown in the Rhone Valley. Small amounts have been planted in Australia and the US.
Sauvignon Blanc – Although from French origins in the areas of Loire and Bordeaux, this varietal is at its best in New Zealand. Sancerre and Pouilly-Fume are two of the best examples from the Loire Valley, and have a light, complex style. These French wines have a bouquet of elderberry (similar to honeysuckle) with dry grassy flavors coupled with citrus and gooseberry, giving it a tart sweetness. Blended with Semillon, it produces dry white Graves and very sweet Sauternes and Barsac (a very sweet wine named for the region). New World Sauvignon Blanc from New Zealand has a more defined style, particularly from the Marlborough region. They often show much more ripe citrus flavors such as grapefruit, along with a subtle asparagus character. Other New World Sauvignon Blanc from Chile and Australia can be more acidic, while California style wines (also called Fume Blanc) lack such intensity.
