Sauternes (wine) Château d'Yquem, can be very expensive, due largely to the very high cost of production. Barsac lies within Sauternes, and is entitled to use either name. Somewhat similar but less expensive and typically less-distinguished wines are produced in the neighboring regions of Monbazillac, Cérons, Loupiac and Cadillac. In the United States, there is a semi-generic label for sweet white dessert wines known as "sauterne" without the "s" at the end and uncapitalized.

Wine Country (California) which are federally designated as threatened. Upland ecosystems drained include mixed California oak woodland, chaparral and savannah woodland. In these upland reaches one finds plentiful black-tailed deer, coyote, skunk, raccoon, opossum, wild turkey, turkey vulture, red-tailed hawk and occasionally bobcat and mountain lion. Prominent higher elevation trees include: Coast live oak, Garry oak, Pacific madrone, California buckeye, Douglas fir, whereas valley oak is prevalent on the Wine Country valley floors. The Wine Country has undergone a boom in tourism. In 1975 there were only 25 Napa Valley wineries; today there are well over 400 wineries in Napa and Sonoma Counties.
