Northwest Chenin Blanc and Sauvignon Blanc
	About Chenin Blanc by Jim LaMar Chenin blanc is arguably the most versatile of all wine grape varieties. Crisp, dry table wines, light sparkling wines, long-lived, unctuous, nectar-like dessert wines, and even brandy are all produced in various areas of the wine world, all of chenin blanc. It might even be said that chenin blanc is France's most successful export variety, if only considering the vine rather than the wine. Although the native region for chenin is the Loire Valley (where the grape is often called Pineau de la Loire), there is less planted in all of France than in most wine-producing countries of the New World. It is planted as Pinot Blanco in Brazil, Chile, Mexico, and Argentina, where there are over 10,000 acres of chenin blanc. Nearly a third of vines in South Africa are chenin blanc, where it is also called Steen. In California, it is the third most widely planted white wine grape. Australia has close to 1,500 acres and New Zealand 500. Resistance to many diseases, vine vigor, and the tendency to early bud break and late ripening suits chenin blanc to grow in climates too warm for many vinifera types. The vine grows well in many soil types and can be very vigorous in either sandy loam or clay loam. Production is fairly consistent at from five to eight tons per acre. At three or four years old, the vines tend to overproduce and may set crops too large to fully ripen in the coolest areas. Chenin blanc grapes are susceptible to both bunch rot and sun burn. In spite of its wide plantings and potential flavor palates, most chenin blanc is made into serviceable, but generally bland wine. A general tendency to over-irrigate and overcrop further reduce most Chenin Blanc to the forgettable. Careful viticultural practices easily overcome chenin blanc's weaknesses and can result in excellent wine. Nearly all the truly memorable Chenin Blancs are French, from Saumur and Savennières (dry), Anjou and Vouvray (off-dry), Coteaux du Layon and Quarts de Chaume (dessert), and Crémant de Loire (sparkling). No matter the style, a certain floral, honeyed character, along with zesty acidity are the sensory trademarks of well-made Chenin Blanc. When conditions are right, Botrytis cinerea adds additional complexity and intensity. The most frequently encountered (but not exclusive) smell and/or flavor elements found in Chenin Blanc-based wines include: Chenin Blanc Smell and/or Flavor Elements Varietal Aromas/Flavors: Processing Bouquets/Flavors: Floral: honey, honeysuckle . Fruity: quince, melon, esp. Honeydew, cantaloupe Wood: vanilla, sweet wood, oak (not usually) Aggressive: iodine, "gym socks" Mineral: flint, smoke Herbal: grass, hay .

	About Sauvignon Blanc by Jim LaMar Charles Wetmore, founder of Cresta Blanca winery, brought the first cuttings of Sauvignon Blanc to California in the 1880s. Some came from the vineyards of the legendary Sauternes Chateau Y'Quem, world's most expensive and famous dessert wine. These plantings did well in the Livermore Valley and Sauvignon Blanc became one of the early favorite dry whites from California. Eventually, Sauvignon Blanc became a varietal with an alias in California, where it is now often known and labeled as "Fumé Blanc". For many years, California wineries made wine from Sauvignon Blanc grapes, but there was almost no consistency of style: some made bone-dry wines after the fashion of the French in the Graves and Loire regions, while others chose to make very sweet, dessert-style wines after the Sauternes and Barsacs. Robert Mondavi deserves credit for this renaming of this varietal to distinguish the style it is made in. Mondavi made a sweet style from the 1966 and '67 vintages, labeling their wine "Sauvignon Blanc", but changed to a dry version in 1968. To denote the change to their customers, they came up with the "Fumé Blanc" name after Pouilly-Fumé, one of the most popular dry-style Loire Valley versions. Rather than copyrighting or trademarking the name, Mondavi offered to allow anyone to use the Fumé Blanc name to market a dry-style Sauvignon Blanc. Note that the term is only used on American wines. "Fumé" literally translates to "smoke," but this has nothing to do with a "smoky" flavor in the wine, although that is a popular notion. It instead refers to the morning fog that covers the Loire Valley and is "as thick as smoke." Any smoke-like smells or flavors in Sauvignon Blanc probably arise from aging in toasted oak barrels and are definitely not due to any inherent character of this grape variety. The varietal identity of Sauvignon Blanc is typically closer to grass, bell-pepper, or grapefruit in nature. It can often even pick up an aggressive "catbox" odor when lacking sun exposure or harvested underripe. Clonal selection and viticultural practices that expose the grapes to more sunlight yield wine that is more melon-like in aroma. Development of hardier clones has helped production levels, which were irregular in humid climates, due to this variety's propensity to develop "powdery mildew" and "black rot". Sauvignon Blanc vines tend to be quite vigorous growers, so it is especially important to manage the canopy by careful pruning and even by thinning leaves and shoots to direct the plant's energy towards ripening the fruit. Unrestrained growth and over-cropping result in neutral-tasting wines of little interest. Barrel-fermentation, although not commonly used for this variety when compared to Chardonnay, can also modify the Sauvignon Blanc aroma and add complexities. Blending Sauvignon Blanc with Semillon is a common practice that can add richness and an extra element of figs to the aroma, softening the sometimes abrasive Sauvignon Blanc character. This blending is widespread in the Graves district of France's Bordeaux region (normally 75-85% Sauvignon Blanc to 15-25% Semillon). In the communes of Sauternes and Barsac, a blend of 60-70% Semillon with 30-40% Sauvignon Blanc is more typical. When allowed to hang, past the normal ripeness point for dry table wine, the grape flavors may be concentrated by the influence of a naturally-occurring mold known as "Noble Rot" (Botrytis cinerea), to make the area's famous dessert wines. Loire Valley wines made from Sauvignon Blanc, such as Pouilly Fumé and Sancerre, are most often 100% Sauvignon Blanc, unblended and usually made without the use of oak. In light of these French traditional methods, the California practices then become somewhat ironic. California producers tend to use the Loire-derived Fumé Blanc name and bottle shape for their blended and oak-aged wines (more like the Bordelais). Meanwhile, the California Sauvignon Blancs that are 100% varietal and most likely without oak in fermentation or aging (distinctly Loire-like practices), are most often bottled in Bordeaux-style bottles! There are wineries who make their Sauvignon Blanc in a dry-style but do not use the "Fumé" name. On the other hand, are there are no regulations limiting the use of "Fumé" to dry wines. This unfortunate inconsistency can be confusing for the consuming public. The American wine industry would probably be best off to adapt some specific guidelines. Besides France and California, Sauvignon Blanc also is produced successfully by New Zealand and South Africa (excellent in both), Chile, Argentina, and, to lesser degrees of production, Washington State, Australia, and Italy, where it is expanding. With fairly good tonnage per acre and lacking the inflationary consumer demand of Chardonnay, Sauvignon Blanc is often a very good value. Sauvignon Blanc is usually quite distinctive and one of the easier varietal wines to recognize by its often sharp, aggressive smell. The most common (but not exclusive) smell and/or flavor elements found in sauvignon blanc-based wines include: Sauvignon Blanc Smell and/or Flavor Elements Varietal Aromas/Flavors: Processing Bouquets/Flavors: Herbaceous: grass, weeds, lemon-grass, gooseberry vanilla, sweet wood Vegetal: bell pepper, green olive, asparagus, capsicum butter, cream Fruity: grapefruit, lime, melon oak, smoke, toast Aggressive: mineral, "catbox" flint With naturally high acidity, Sauvignon Blanc is always tangy, tart, nervy, racy, or zesty, and this character pervades even sweet and dessert versions, keeping them from being cloying and sticky-tasting. Dry-style Sauvignon or Fumé Blancs are very versatile in accompanying foods and can handle components such as tomatoes, bell peppers, cilantro, raw garlic, smoked cheeses or other pungent flavors that would clash with or overpower many Chardonnays and almost all other dry whites. In fact, Sauvignon Blanc is probably the best dry white wine to accompany the greatest variety of foods.
