The Barossa Valley in Australia is one of the New World's most interesting wine regions, having been established in the late 19th century by German settlers. The region benefits enormously from the relatively temperate climate, which ranges from being hot on the lower parts of the valley, to quite cool as the altitude increases on the valley slopes. Barossa Valley produces mostly Shiraz wines, and has become one of the key Australian regions for this distinctive grape varietal which has gone on to be a major grape for the Australian wine industry. Despite suffering from a poor reputation in the mid 20th century, by the 1980s, plenty of unique and forward-thinking wineries set up in Barossa to take advantage of its excellent climate, and set about producing the excellent red and white wines which the region is famed for today. Semillon was, at one point not so long ago, widely believed to be one of the most grown grape varietals in the world. Whilst today the numbers of Semillon grapes has dropped considerably, it remains a widely planted grape with vineyards all over Europe and the New World dedicated to making the most of this special and flavorful varietal. The grapes are recognizable by their golden color, and the fact that they can take on a pinkish hue in particularly warm climates. The wines the Semillon grape produces are notably varied, and are often very crisp and dry, or sweet and soft, full of a wide range of flavors Commonly, dry Semillon wines are particularly citrus in flavor, with a delicate and summery bouquet. The vine is hardy and vigorous, and notable for being easy to grow and produce high yields from.
