Riesling is a white wine grape which has its birthplace in Rhine wine region of Germany. This grape is used in making of semi-sweet, sweet and sparkling white wines all over the world. The grape is grown in suitable climatic conditions globally. In Australia, this is grown in the following regions:
Clare Valley: This wine region of Australia accounts for the highest vineyard area under Riesling grapes. This region is situated in the state of South Australia, north of Adelaide capital city. In fact, this region is known for Riesling wines essentially. The Horrocks Highway passes through this region. It is a part of the Mount Lofty Ranges Zone. Out of the total planted area of this region, Riesling was the second important wine grape planted as it occupied 21.8% of area.
Eden Valley: The Eden valley wine region is also situated in South Australia and to the north-east of Adelaide. It is bordered on west by Barossa Valley wine region and on east by Adelaide Hills wine region. Riesling wine grape is the second important variety to be planted here.
Riverland: Riverland region is the third important Riesling growing region having about 12 percent of the total Riesling growing area in Australia. This region is in South Australia. It begins from where the Murray river enters South Australia after flowing on the border of New South Wales and Victoria. The region is one of the largest wine growing regions of Australia.
Riverina: Riverina region is located in New South Wales to the east of Australian Capital Territory. The region is centred around the town of Griffith. It is a part of the Big Rivers wine region and depends heavily on the Murrumbidgee river irrigation scheme for growing vines. The wine growing area of this region is smaller than the Riverina area itself.
Murray-Darling: Murray Darling basin is another region where Riesling wine grapes are grown but is not as well known for it, as it is for Chardonnay white wines.
Among the popular white wine varieties is Riesling. This is a white wine grape which is a native of Germany. The first wines from this grape were made in Germany and over a period of time, this spread to other regions of the world. Riesling wine grapes are now grown in all wine producing countries of the world. Germany and Alsace region of France account for the most of this share, growing as much as 42 percent of these grapes among themselves.
Riesling wines are generally more expensive than other varietals. You might not believe the fact that, in Germany, it is the smell of petrol which is used to adjudge which is a better Riesling than the other. The stronger the aroma, the better is the Riesling. The most expensive of these wines are the ones which have been harvested late. The fruit is allowed to hang on to the vine well beyond its picking time to let the water evaporate naturally. This wine has high levels of acidity and pairs well with diverse range of food items. Another key factor that makes these wines expensive is the fact that these have very good cellaring potential. Natural high acidity and the added sugars help these wines to age well and become better year after year. It is also to be noted that most of Riesling wine consumption is when it is young.
In Australia, this is grown in regions having some characteristics of limestone topography, such as Clare (22 percent) and Eden valleys. For this reason, riesling wines develop a distinctive lime note. The wine is exported to a number of countries, with the USA being the single most important importer of this wine (accounting for 40 percent of its exports).
In Australia, this land area under this wine grape has been on decline since the last few years. It was at its lowest in 2015 since 2001. This declining trend has been attributed to decline in demand. However, whether Australia will cease to be a land of Riesling in future is something which is worrying the wine experts.
