Vins Doux Naturels Flashcards
The term Vins Doux Naturels (VDN) describes a category of French wines made sweet by the addition of spirit during fermentation. There are a number of PDOs for these wines, spread throughout Roussillon, Languedoc and the southern Rhône, with around 80 per cent of production coming from Roussillon.
The general climate in all the VDN PDOs is
Mediterranean.
——– is the warmest and driest region and is influenced by the Tramontane wind all of which leads to greater transpiration from the grapes during the end of ripening, and hence a greater concentration of sugar.
Roussillon
A grape with a high level of sugar can ferment for longer, producing more alcohol, before reaching the desired level of residual sugar for the final wine. T/F
True
How is a greater concentration of sugar in the grapes is more beneficial?
Although this reduces juice yield, less spirit is needed to fortify a wine
The majority of VDNs are produced from ——
Muscat or Grenache Noir
This Muscat variety is the most widely planted in France.
Muscat Blanc à Petits Grains
Muscat Blanc à Petits Grains suited to Mediterranean climates because
It is tolerant of dry weather where rain during the growing season is scarce.
Muscat Blanc à Petits Grains is susceptible to ….
powdery mildew/oïdium, botrytis bunch rot and mites
This Muscat variety has bigger grapes than Muscat Blanc and achieves high sugar levels.
Muscat of Alexandria
——- is a late ripening variety with good drought resistance, making it suitable to Mediterranean climates. It produces high yields, but can be relatively pale in colour unless these are controlled.
Grenache Noir
Why is Grenache Noir suitable for production of fortified wines?
It accumulates sugar quickly
Grenache Noir is susceptible to —-
coulure at fruit set,
downy mildew,
phomopsis and
botrytis bunch rot
Why is a shady a canopy is required for growing grapes for VDNs?
To reduce the chances of sunburn and excessive grape shrivelling
Grapes for VDN must be picked with a minimum of 14.8% abv potential alcohol.
True
For VDN Late harvest or botrytized characters are not desired.
True
For VDN Grapes tend to be hand-harvested, and there may be several passes through the vineyard depending on the ripeness of the crop.
True
Why is a neutral spirit of 95–96% abv is used in the production of VDNs?
so that the character of the spirit does not compete with the character of the base wine and/or maturation.
_____ are produced by adding grape spirit to stop fermentation early to give a sweet, fortified wine.
VDNs
Spirit is added when the fermentation reaches —— abv to makes wines of 15–18% abv.
5–8%
Why VDNs do not have a particularly spirity character?
Only approximately 5–10 per cent of the volume of the wine is made up of the fortifying spirit.
What are the two VDN Appellations in the Rhône?
Muscat de Beaumes-de-Venise and
Vin Doux Naturel Rasteau
The vines of —— are planted on terraces on the south-east facing slopes of the Dentelles de Montmirail
Muscat de Beaumes-de-Venise
Grapes for the production of red and rosé VDN wines
Muscat à Petits Grains Rouge, a dark-skinned mutation (Brown Muscat in
Australia)
