Muscat d’Alexandrie


Synonyms
Muscat Romain (France); Salamanne (Italy); Zibibbo (Sicily); Hanepoot (South Africa); Moscatel Gordo (Spain).

 Origin and cultivation background
Muscat d’Alexandrie is one of the oldest cultivars in South Africa, dating back to the Van Riebeeck era. The French name of the cultivar suggests it could have originated in the region close to the ancient harbour of Alexandria. There are indications that it was cultivated by the ancient Egyptians, Greeks and Romans. Although it occurs in all the warm wine countries, it is probably most popular in
South Africa, where this multipurpose cultivar is used for table grapes, raisins, grape juice, moskonfyt, and natural table and liqueur wines. There is also a red mutation (Red Hanepoot), which is still cultivated on a very limited scale. White Hanepoot is found in all the regions, with the largest plantings in Worcester, followed by the Olifants River area.

Cultivation characteristics
Muscat d’Alexandrie is moderately vigorous and has a semi-upright growth habit. Particular with regard to soil and climate — prefers reasonably deep soil with good water-retention ability and a moderate climate, but warm conditions during flowering. It is very fertile and has a high yield potential when spur pruned. Best adapted as goblet (bush) vines or trellised on low trellises.

Produces short, thick shoots (short internodes below), which become thinner towards the tips. The canopy is dense because of numerous water shoots. Careful attention should be paid to canopy management practices — particularly suckering. Susceptible to oidium, downy mildew and anthracnose, and very susceptible to erinose and bud mites. Also susceptible to sunburn damage — older leaves often display irregular yellow to brown uneven sunburnt spots. It is an old cuItivar which means that many vines have degenerated — reproductive material should therefore be selected carefully. Recently, thorough selection and virus elimination have solved many of the problems affecting successful cultivation, e.g. poor setting in older clones. Problems regarding compatibility with a variety of rootstock cultivars have largely been eliminated byplant improvement procedures.

Carménère


Origin:  France

Description: small, winged bunches; berries average, spherical, beautiful bluish black, pulps soft, herbaceous taste.
Carménère is very similar to Cabernet franc.

Production: budburst fairly early, It is tempremental, vigorous and not very fertile on the basal buds and longer pruning is recommended. It is sometimes prone to the coulure and should not be planted on fertile soils or in cold areas. Carménère does not have particular sensitivity to diseases, except maybe rot. Ripens late season.

Availability: grafted vines of clone NE   1 A are already available

Type of wine/Flavours: Wines are rich, well coloured (about one third more anthocyanin that Cabernet Sauvignon), with a high tannic content but sometimes it could be low in acidity and a little bitter. The young wines are characterized by their herbaceous taste. A vegetal character is usually dominant unless it reaches full maturity

Grenache gris



Origin

This cultivar is a mutation of white Grenache.

Description
The description matches that of Grenache noir, except for the berry colour which is yellow-green at full ripeness

Phenology
Time of bud burst:  early, a few days before Grenache noir.
Time of maturity: mid season, slightly earlier than Grenache noir.

Production
This cultivar seems to be less susceptible to rain damage than Grenache noir and proves to be a little earlier. It is resistant to wind, has an upright habit and is well suited to drought conditions (gravel or stony soils). Grenache blanc, like other types of Grenache, is sensitive of magnesium deficiency.

Susceptibility to diseases and pests
Grenache Blanc is very sensitive to botrytis, phomopsis, downy mildew and bacterial diseases. It is rather resistant to powdery mildew, leaf hoppers and mites.

Type of wine/Flavours
Clusters are large while the berries are medium. Grenache Blanc are used for the preparation of fortified wines but also allows to obtain interesting dry white wines with a long finish, full bodied but sometimes lacks a little acidity.

Marsanne


Origin - France

Production

Production       - high
Vigor                - average
Acid                 - good
Ripens             - end February -early March
Bunch              - average ot large
Berries             - small to average, rosy at full maturity, juicy

Susceptible to rot, oidium, drought and wind

Wine and production ability

Marsanne is in most cases associated with Roussanne. Vinified alone, the wine is lighter than the latter, lower in acid, with less bouquet and finesse, ageing unpredictable and disappointing. Its aromatic potential is however, higher than white Grenache but too low for a typical blend. Instead, it gives excellent sparkling wines, the best known is the Saint Péray. Part of the vine appellations Saint Péray, Hermitage, Crozes-Hermitage, Saint Joseph, Cotes du Rhone, Corbières, Cassis, ... .

Aromas of dried apricot, acacia, beeswax, quince, spices, nuts (almonds, hazelnuts and walnuts), fresh lychees, honey, white peach, apple cooked, liquorice

Marsanne in France

Marsanne is a classic grape varietal in the Rhone Valley, and is found both in Northern and Southern Rhone. It reaches its peak in the sublime wines of Hermitage, where it is often blended with Roussanne. It is one of the 8 white grapes permitted in the Cotes du Rhone appellation, and is a significant component (usually 30%) of the Coudoulet de Beaucastel white.
  

Flavors and Aromas

Marsanne tastes of melon (particularly honeydew) and honeysuckle. It also has a tendency for picking up the mineral flavors of its soils, and is therefore important to winemakers who wish to express the character of their terroir. It has a golden straw color.

Roussanne





Origin - France

Production

Production       -  5 - 7 t/ha
Vigor                - average
Acid                 - good
Ripens             - end February - early March
Bunch              -small,sylindrical, compact
Berries             - Spherical, small, white, almost gold rosy at full maturity, slightly juicy.

Prone to slight rot on fertile soils, oïdum susceptible

Wine and production ability

Roussanne is a noble grape capable of producing wines of very high quality, with a fine, yellow straw colour, and a bouquet reminiscent apricot, hawthorn, green coffee, honeysuckle, honey, discreet narcissus and iris. Wines have good balance en acidity and are suitable for aging.

Roussanne gives extra aroma en elegance to other white cultivars in blends.

Roussanne in France

Roussanne is one of the four white grape varietals permitted in Châteauneuf-du-Pape, and is the sole component of Château de Beaucastel’s excellent Vieille Vignes. Elsewhere in Chateauneuf-du-Pape, it is often blended with Grenache Blanc, whose richness and crisp acids highlight the pear and honey of the Roussanne.

Roussanne is also found in the northern Rhône valley, where it is blended with Marsanne in Hermitage, Crozes-Hermitage, and Saint Joseph, and in the Savoie region, where it is known as Bergeron.

Roussanne in the Vineyard

Roussanne is a shy producer, and produces small grape clusters with small berries.

Flavors and Aromas

Wines made from Roussanne are fine and complex, with distinct honey, floral and apricot flavors. Unlike many white wines, Roussanne ages very well due to its acidity and strength. 

Macabeu



Synonym - Viura
Origin - Spain

Description:
Bunches very large, pyramidal, very ramified, often winged, loose;
berries spherical, average, gilded yellow, juicy

Production:
Budding rather late, a few days after Carignan. Very vigorous cultivar, upright growth habit, sensitive to wind. It is rather delicate, sensitive to oïdium, a little less to powdery mildew and not well adapted to wet and cold soils (grey rot) as well as very dry soils where it is sensitive to Esca.

Ripens late season.

Wine and production ability

Depending on terroir, Macabeu produce good, fruity wines with a yellow straw colour. Acid sometimes a bit low. Is also used for the production of sparkling wines.

Flavours of anise and honey.

In France it is cultivated in the following areas: Côtes de Roussillon, Banyuls, Maury en Rivesaltes. 

Vermentino



Origin - Italy

Description:

Bunches truncate, loose, Average to large with well developed bunch stem.

Berries average size, slightly  ellipsiodal, rosy at full ripeness.

Production

Budding early, good production and strong vigor, must be trellised because it is rather sensitive to the wind. Also sensitive for oïdium and slightly prone to Botrytis.

Vermentino performs well in warm areas with dry, less fertile soils.
Ripens late mid season

Wine and production potential

 Vermentino produce a wine with good quality, full with good balance and a beautiful pale colour, sometimes lacks acidity.

Wine is aromatic with interesting flavors like hawthorn, chamomile, pear en hazel nut
