Mike:

Other techniques associated with Old World winemakers include higher fermentation temperatures and a period of extended maceration following fermentation where the wine can leech more phenolic compounds from the grape skins.

Lisa:

This can create more tannic and austere wines with more layers of complexity that require longer periods of bottle aging in order to mature. In contrast, the technique of transferring the must into oak barrels during fermentation and inducing malolactic fermentation early is more commonly associated with New World wine regions and wines that are softer and mature earlier.

Old World winemaking is often terroir driven with emphasis being placed on how well the wine communicates the sense of place where it originated. For example, a winemaker making a Riesling from the Mosel will often try to highlight the unique traits of the Mosel wine region (such as its slate soils) with the wine expressing those traits in the form of minerality.

New World Wines in Industrial Age

Vine cuttings from the Cape of Good Hope were brought to the penal colony of New South Wales by Governor Phillip on the First Fleet (1788). An attempt at wine making from these first vines failed, but with perseverance, other settlers managed to successfully cultivate vines for winemaking, and Australian made wine was available for

Classification Of Wine

Regulations govern the classification and sale of wine in many regions of the world. European wines tend to be classified by region (e.g. Bordeaux, Rioja and Chianti), while non-European wines are most often classified by grape (e.g. Pinot noir and Merlot). Market recognition of particular regions has recently been leading to their increased prominence on

Grape Varieties

Wine is usually made from one or more varieties of the European species Vitis vinifera, such as Pinot noir, Chardonnay, Cabernet Sauvignon, Gamay and Merlot. When one of these varieties is used as the predominant grape (usually defined by law as minimums of 75% to 85%), the result is a “varietal” as opposed to a

Popularity and Backlash of Chardonnay

Due to the “malleability” of Chardonnay in winemaking and its ability to reflect its terroir, there is not one distinct universal “style” or set of constants that could be applied to Chardonnay made across the globe. According to Jancis Robinson, a sense of “smokiness” is one clue that could be picked up in a blind

TOGGLES 1
During the 1970s producers started to reduce the quantity of white grapes in Chianti. In 1995 it became legal to produce a Chianti with 100% Sangiovese. For a wine to retain the name of Chianti, it must be produced with at least 80% Sangiovese grapes. Aged Chianti (38 months instead of 4–7), may be labelled as Riserva. Chianti that meets more stringent requirements may be labelled as Chianti Superiore, although Chianti from the “Classico” sub-area is not allowed in any event to be labelled as “Superiore”.
TOGGLES 2
The original area dictated by the edict of Cosimo III de’ Medici would eventually be considered the heart of the modern “Chianti Classico” subregion. As of 2006, there were 7,140 ha (17,640 acres) of vineyards in the Chianti Classico subregion. The Chianti Classico subregion covers an area of approximate 260 km2 (100 square miles) between the city of Florence to the north and Siena to the south.
TOGGLES 3
The four communes of Castellina in Chianti, Gaiole in Chianti, Greve in Chianti and Radda in Chianti are located entirely within the boundaries of the Classico area with parts of Barberino Val d’Elsa, San Casciano in Val di Pesa and Tavarnelle Val di Pesa in the province of Florence as well as Castelnuovo Berardenga and Poggibonsi in the province of Siena included within the permitted boundaries of Chianti Classico.

There is no simple definition of a dessert wine. In the UK, a dessert wine is considered to be any sweet wine drunk with a meal, as opposed to the white fortified wines (fino and amontillado sherry) drunk before the meal, and the red fortified wines (port and madeira) drunk after it. Thus, most fortified wines are regarded as distinct from dessert wines, but some of the less strong fortified white wines, such as Pedro Ximénez sherry and Muscat de Beaumes-de-Venise, are regarded as honorary dessert wines. In the United States, by contrast, a dessert wine is legally defined as any wine over 14% alcohol by volume, which includes all fortified wines – and is taxed more highly as a result. This dates back to a time when the US wine industry only made dessert wines by fortification, but such a classification is outdated now that modern yeast and viticulture can produce dry wines over 15% without fortification, yet German dessert wines can contain half that amount of alcohol. Examples include Sauternes and Tokaji Aszú.

In the absence of other techniques, makers of dessert wine have to produce their sugar in the vineyard. Some grape varieties, such as Muscat, Ortega and Huxelrebe, naturally produce a lot more sugar than others. Environmental conditions have a big effect on ultimate sugar levels – the vigneron can help by leaving the grapes on the vine until they are fully ripe, and by green harvesting and pruning to expose the young grapes to the sun. Green harvesting reduces the number of bunches on a vine early in the summer, so that the sugar production of the leaves is divided between fewer bunches. Unfortunately the vigneron cannot control the sun, but a sunny year can help sugar levels a lot. The semi-sweet Auslese wines in the German wine classification are probably the best example of this approach; most modern winemakers perceive that their customers want either fully dry or ‘properly’ sweet dessert wines, so ‘leave it to nature’ is currently out of fashion. But most of the Muscats of ancient times were probably made this way, including the famous Constantia of South Africa.
