Viticulture 4 Virgins

Part II: Grape Expectations

We've already mentioned in 'Viticulture for Virgins Part I' that the varietal of grape grown in any region is determined by the location. Let's look into this further.

Horses for Courses

The realisation that certain varietals grow better in certain regions didn't happen overnight. The Europeans discovered this more by trial and error - over hundreds of years - than by scientific research.

Advances in viticultural practices (trellising, harvesting) and modern technology (eg refrigeration) may mean that ideal grape type may have changed, however -probably because of traditional planting restrictions in Europe - implementation of this change has been slow, if at all.

Market Demand - obviously there's no point in increasing plantations of Chardonnay in Australia at the moment. No-one wants it. Consumers are looking for more interesting whites.

Here again the New World boasts supremacy. Without appellation contols, they can plant whatever they want!

But can they keep up with consumer demand? If that were so, why is there such a glut of Chardonnay out there? New vines take up to 7 years to produce a decent yield, that's why.

The consumer has changed his mind 15 times by then, and probably wants Chardonnay back. Nature takes a little longer to respond to consumer demand than man does.

Ripening - is there enough sun and warmth to ripen Shiraz? Is it cool enough to maintain desirable acidity in Sauvignon Blanc? If not, there's a myriad of varietals to choose from that will be more suitable to a region. If all else fails, modern science just creates new varietals to suit growing conditions. [See Tarrango in the list at right]

Tolerance to Climatic Hiccups - some regions are prone to drought, or Spring frosts. These factors can have horrific affect on new buds, or fruit setting. It's important that the varietals chosen for a particular region can hold up in times of adverse conditions.

Old World Tradition -v- New World Innovation?

If I may digress into my marketing head for a moment ...

Interestingly enough, the New World criticizes the Old World for adhering to planting restrictions - particularly in France where not only type of grape but yield is limited by appellation controllée laws.

At the same time, several articles in wine press claim the New World [particularly Australia] has revolutionised the wine industry globally with its "brand-building discipline".

Building brands is exactly what the French have been doing all the time. Just because they don't do jingles, fluoro-coloured labels and tacky merchandising to go with it, we all know that a 'Bordeaux' is not just a region, likewise a 'Burgundy', 'Champagne', or a 'Rhone Blend'. The wine world knows what to expect in terms of taste and quality from these brands ... oops, wines.

Early to Ripen:Early to Harvest

Grape varietals don't all ripen at once, so they can be split into different maturity groups. This is important when laying out the vineyards and determining which grapes are to be planted. Obviously if all grapes ripened at the same time, by the time you have harvested the fruit from the whole property, the last ones may be a bit worse for wear!

Thus, large vineyards often have different varietals growing in different sections which mature at different times.

Those grape varietals that need less heat or sun to mature are called 'Early Ripeners'. As the amount of sunlight has a direct bearing on the colour of a grape's skin, it's not difficult to understand that most early ripeners are white grapes: eg, Pinot Noir, Chardonnay, Sultana, Traminer, Verdelho.

What? - you say - Pinot Noir is a red grape! True, but the colour in a wine comes from the skin, [flesh of all grapes is white] and when Pinot Noir is used in Sparklings or Champagnes, the colour of the skin is not needed - and neither is a high level of sugar. More about this in the winemaking pages. So, for this purpose, they are early ripeners.

[Wine is not all red and white - there are pink areas!]

Mid-season ripeners are the next to mature and be harvested. This group includes all the regulars, eg: Cabernets (Franc, Sauvignon, Ruby ...), Shiraz, Merlot and whites that need a little more sugar, like Savignon Blanc, Marsanne, Riesling, Semillon.

Finally the late ripeners, which by now I'm sure you realise are those varietals which need more sugar: Grenache, Muscats, etc.

Grapes can move between these maturity groups depending on climate. Riesling, for example, is able to reach adequate flavour ripeness at relatively low sugar levels in very cold regions. This is one of the reasons it is one of the most important grapes in Germany.

Early-Picked v Early Ripening

Don't confuse 'early-picked' with 'early ripening'.

Early-picked refers to grapes picked at an earlier time than optimum ripening requires. This is done to reduce the sugar level in a wine.

Of course, 'late-picked' means the opposite - ie picked late to increase sugar levels.

A Sea of Varietals

There are literally hundreds of different grape varietals used for wine-making around the world, and research (particularly in New World countries) is resulting in new clones, custom-made for specific regions all the time.

Commercial wines from all over the world are mostly grown from grapes of the Vitis vinifera family. Originating in Asia, this species will die in freezing temperatures, and is prone to mildews and other bugs. The viticulturalist monitors these problems [more on "Vineyard Dramas" page] closely as they can be devastating not just to one vintage, but to the survival of the vineyard.

Whilst the whole gammut of grape varietals could be listed here, we'll stick to the more popular ones, and maybe a few lesser known, but important, ones - or I'll never get this site written! [See table right]

Varietal Notes
Barbera

One of the world's most widely planted red grapes. Important in Italy, Argentina and parts of California. Retains higher acidity even in hot areas. Intensely coloured and astringent.

Cabernet Franc

Important variety in St Emilion and Pomerol,France. These areas of north Bordeaux have less maritime influence and are subject to cooler winters. This red prefers cool climates - budbursts and ripens early. Makes softer, higher quality wines than Cabernet Sauvignon. Mostly blended

Cabernet Sauvignon

Comes from Bordeaux, France where it is the major variety in Medoc wines. Considered the world's premium red grape. Grapes have good tolerance of bunch rot, and damage as berries are small and tough. Vines don't like damp, clay soils - they need drainage. The Medoc has gravelly, well-drained soils. Takes a long time to ripen so likes hot summers and long mild autumns.

Carignan

Red grape which makes wines of good colour but average quality. Takes time to age, so is often blended with faster aging grapes such as Grenache or Cinsault Spanish name - Mazuela. Used for bulk wines in USA. Likes hot, dry climates.

Chardonnay

Versatile white grape widely planted in many wine regions around the world. So common in Australia that it has fallen out of favour with wine buffs. Used in Champagne - blended with Pinot Noir & Pinot Meunier preferably. Easy to grow, good yields, few problems.

Chenin Blanc

Used mainly in Loire Valley, France for still and sparkling white wines. Widely grown in South Africa - where it's sometimes called Stein. Has good acidity so is blended to balance other whites.

Cinsaut

Southern France varietal red. Often mispelled 'Cinsault'. Sometimes a table grape, sometimes wine. Adapts well to hot, dry climates, tough skins resistant to rain damage, but prone to fungal rots. Makes average quality, low tannin wine - often blended.

Colombard

One of the whites used for Cognac in France, although larger plantings exist east of Gironde in Bordeaux. Often a table grape. High-yielding, tolerant of rot and mildew. High acidity, and has a distinct varietal flavour.

Crouchen

White grape originating from (but not grown there much these days) south-west France. History of being associated with the name Riesling in South Africa and Australia - however it is not Riesling. Real problem child ... doesn't ripen well in cool regions, and is very susceptible to rots and mildews in hot regions. Thus its decline in favour globally.

Durif

This majestic red, also known as 'Petite Verdot' or 'Petite Sirah' originates from the Rhone Valley, France. This grape ripens late and is tricky to grow. Durif offers wines of intense, blue-black colour, guaranteed to stain your teeth, and high tannins which require long ageing before drinking. However, Durif grown in warmer areas presents as a faster aging wine - probably due to advanced characteristics in the grapes - and is more approachable at younger age. Also used for Port.

Frontignac

The official name for this grape is 'Muscat a' petit grains" (Muscat of small berries), and it can come in white or coloured varieties. The ripe berries wilt and shrivel quicly to concentrate sugar - thus its extensive use in sweet fortified wines called Muscats. The white variety is commonly used for table wines, which coloured grapes preferred to fortifieds.

Grenache

Spaniards call this red "Garnacha". Blended in southern France (Rhone) popularly with Shiraz and Mataro or Carignan. Before Cabernet Sauvignon took its place in the 1990's, Grenache was important grape in Australia. Likes hot, windy conditions. Wind is important as it's also prone to rots, fungus, mildew, etc. Makes wines of low colour, but faster aging. Most often used for Rose` or Tawny Port.

Malbec

Red grape known as 'Cot' in west France, where it's decreasing in popularity due to productivity issues. Grown near Bordeaux and Loire Valley, France as a blender. Important grape in Argentina. In Australia it has been confused with Dolcetto and Inta Amarella. Irregular crops have been improved through cloning. Rich in colour and tannin and used for blending mostly.

Marsanne

As the name suggests, this white is another originator of France, where it is grown in the Rhone region. Similar to Viognier, the wines made from Marsanne have little varietal character and age quickly. Don't cellar this one - just drink it.

Mataro

In Provence, France, this red is known as Mourvedre, and in Spain (where it holds more importance) is called Monastrell or Morastell. Recovers well after frost, and yields well. Hardy grape, and needs warmth to ripen. Makes neutral wines of high astringency. Good for blending.

Merlot

The principal red of Bordeaux. Sensitive to salinity, enjoys cool damp clay soils. Makes softer wine than Cabernet Sauvignon, ripens earlier so avoids the summer rains and autumn winds from the Bay of Biscal. These two wines are often blended. Wines made from Merlot age quicker than other red wines.

Palomino

White grape used for Sherry and other fortifieds - makes low quality table wines. Important to Spain - providing most of the wines for Sherry (Jerez). High sugar content, low acidity and neutral flavour.

Pedro Ximines

Also used in Spain for Sherry. This white is tender-skinned and thus prone to weather damage and rots. Sometimes blended into table wines.

Pinot Noir

Burgundy, France's favourite red grape, and one of the most popular varietals for white sparklings and Champagne. In Germany and Switzerland, it's known as 'Spätburgunder'. An old varietal, it is claimed there are over 1,000 different clones. Has little colour, and excels in cool areas. Has distinctive varietal characters ranging from "barnyard" to "cherry". Depending on which turns you on, choose your Pinots carefully!

Riesling

The white grape king. Widely grown around the world. Originated in Germany - prolific in Rheingau and Mosel regions. Moderate producer, Riesling ripens well in many conditions, and produces distinctive, aromatic wines.

Sangiovese

An Italian red grape, most prevantly used in Italy's Chianti, becoming more popular in the north-eastern area of Victoria, Australia.

Sauvignon Blanc

This white grape put New Zealand on the map, at the same time as it was decreasing in plantings in France. A large leaf-area:fruit ratio enables successful capture of sunlight to produce sugars in colder regions. Wines have distinct varietal characters.

Semillon

This poorly identified white historically gets confused with Chenin Blanc, Crouchen and Riesling - particularly in Australia. In Bordeaux it claims fame as second most important white. Berries split easily in rain when ripe, leaving it susceptible to rot - which can be a good or bad thing, depending on what you want to do with the grapes. In Australia, botrytised semillon is probably the most famous dessert wine in the country.

Shiraz

The red grape king in Australia - however not necessarily so important elsewhere. Also known as 'Syrah'. Red wines from Hermitage region of Rhone Valley are 100% Shiraz. Yields well in variety of climatic conditions, but berries tend to wilt when ripe - making mechanical harvesting difficult.

Tarrango

An Australian-born red grape developed by CSIRO as a cross-breed of Sultana and Touriga grapes. Makes a light-bodied red table wine with good acidity, and faster aging. Don't hold your breath looking for it in an Australian bottle shop, though.

Touriga

Red Port variety, more succinctly called Touriga Nacional, of Douro Valley in Portugal. Mostly used in fortified wines. Excellent colour and flavour for Ports. Sometimes used as productive blender in table wines.

Verdelho

This Portuguese white varietal, known on the island of Madiera as 'Gouveio', has until recent days been used for fortified wine. In the new millenium however, table wines have been popping up in the bottle shops made from this varietal. Ripens early, and offers distinct tropical fruit characters in hot regions.

Viognier

Wine made from this white have been traditionally blended with Marsanne and Roussanne to increase complexity as it's pretty ordinary on its own. [Mind you, I've had workmates threaten to string me up for saying that] Often apricot flavours and aromas, ho hum. Ages quickly. New kid on the block in Australian market is Shiraz/Viognier - emulating the Cote Rotie wines of France.

Zinfandel

Common red varietal in California, USA. Reportedly the same grape as Primitivo in Italy and Mali Plavac (or more distinctly Crljenak - a parent of Mali Plavac) in eastern European countries, eg Croatia. Wines made from Zinfandel have distinctive Raspberry characters.
