History

While most of Australia's wine industry was directly influenced by the involvement of the British, the Barossa Valley was shaped by the influence of German settlers fleeing persecution from the Prussian province of Silesia. In 1841, the South Australian Company (under orders of one of its shareholders George Fife Angas

) chartered three ships to Silesia to offer refuge and land in the Barossa Valley to any settler willing to volunteer to help establish the colony. Nearly 500 families accepted the offer and settled in the Barossa Valley. After trying many types of agricultural crops, the settlers found the warm fertile valley to be ideally suited for viticulture

The early focus of the Barossa wine industry was on the production of Riesling, a German wine

 which ushered in a period of fortified wine production that coincided with the plantings of many red grape wine varieties like Shiraz and Grenache. These "port-style wines" would become the center of the Barossa wine industry for decades to come. When the focus on the Australian wine industry shifted in the mid-20th century to production of premium, non-fortified wines, the Barossa was regarded as an "inferior" wine region compared to cooler climate regions such as Coonawarra

 and Padthaway. This was partly due to the extensive association that the Barossa had with Shiraz, including vast old vines plantings that were several decades old. During this period Shiraz was considered a very "common" variety that was not as fashionable as the prestigious Cabernet Sauvignon that was popular in the world's wine market. Most of the grapes produced in the Barossa Valley during this time was used as part of anonymous blends with the name "Barossa Valley" rarely appearing on wine labels.

By the late 20th century, the reputation of the Barossa Valley started to change as several small boutique varieties began earning critical acclaim for their Barossa Valley wines. In particular, Barossa Shiraz became so well known internationally that it was considered its own unique style of Syrah that was distinctive of the grape's expression in other regions like Côte-Rôtie, Châteauneuf-du-Pape and California. This style of big, full bodied Shiraz with rich, chocolate and spice notes became synonymous with not only the Barossa Valley but with Australian wine in general. In the words of Master of Wine

Climate and geography

In general the Barossa Valley has a continental climate but its series of transverse valleys and sloping hills does produce a wide range of mesoclimates. Temperatures vary from very warm on the valley floors to progressively cooler at higher altitude

Despite its reputation as a "warm climate region", main of the Barossa Valley's climate figures are not that dissimilar from the relatively cooler Margaret River Valley in Western Australia-though the Barossa does have a wider diurnal temperature range. During the heat summation and mean temperatures during the October to April growing season, the region receives about 1710 heating degree day

Most of the Barossa Valley makes extensive used of irrigation to supplement the region's low rainfall supply during the growing season. However, concerns about water supply

The generally hot climate of the Barossa Valley usually means that the grapes become ripe very easily with high levels of sugars and low levels of acids. Winemaking in the Barossa often utilizes the process of acidification in order to add balance to the wine. The high alcohol levels from the fermented sugars may be offset by various winemaking practices including reverse osmosis
