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. The purple skinned grapes of the Grenache varietal have quickly become one of the most widely planted red wine grapes in the world, flourishing in several countries which have the correct conditions in which they can grow to ripeness. They thrive anywhere with a dry, hot climate, such as that found in central Spain and other such arid areas, and produce delightfully light bodied wines full of spicy flavors and notes of dark berries. Their robustness and relative vigor has led them being a favorite grape varietal for wineries all over the world, and whilst it isn't uncommon to see bottles made from this varietal alone, they are also regularly used as a blending grape due to their high sugar content and ability to produce wines containing a relatively high level of alcohol.
