Vins Doux Naturels Flashcards
Learn why various VDNs taste the way they do by examining the different growing environments, soils, climate, grape varieties, production, and maturation methods for key appellations making this style of fortified wine. Key styles of VDN are covered in this deck.
The majority of Vins Doux Naturels come from which region in southern France?
Roussillon
What is the general climate for all French PDO Vins Doux Naturels?
Mediterranean
The warmest and driest region of all French regions making Vins Doux Naturels is _____.
Roussillon
What environmental influence affects Roussillon that leads to its grapes having greater concentration of sugar?
Explain.
Tramontane wind, which increases transpiration in the grapes during the end of ripening which increases sugar concentration.
How is the concentration of sugars in Roussillon grapes beneficial to the winemakers (vis-à-vis fortification)?
The grapes are so sugar-rich and concentrated the potential alcohol is high, which means winemakers will not have to add as much spirit to fortify the wine (read: it won’t be as diluted, but the wine yield will be smaller).
The two major grapes that go into making French Vins Doux Naturels are _____ and _____.
- Muscat;
- Grenache.
What are the similarities between Muscat Blanc à Petits Grains and Muscat of Alexandria (through the lens of French Vins Doux Naturels)?
- Both tolerant to dry weather;
- Both susceptible to powdery mildew and botrytis bunch rot.
What are the physical and organoleptic differences between Muscat Blanc à Petits Grains and Muscat of Alexandria (through the lens of French Vins Doux Naturels)?
Muscat Blanc
- Most widely planted Muscat variety in France;
- Smaller grapes than Muscat of Alexandria;
- Greater intensity of aroma and flavor;
- Trends making dry wines or used as a blending component in dry wines.
Muscat of Alexandria
- Plantings are in decline;
- Larger grapes than Muscat Blanc;
- Produces wines that are less refined than Muscat Blanc.
Why is Grenache Noir well suited for Mediterranean climates?
- Late ripener;
- Resistant to drought.
Why is Grenache Noir well suited to making fortified wines?
Accumulates sugar quickly
What natural threats is Grenache Noir susceptible to (all of which can reduce yields)?
- Coulure at fruit set;
- Botrytis bunch rot;
- Downy mildew;
- Phomopsis.
For unaged styles of Muscat VDN, what must be done in the vineyard to reduce chances of sunburn and grape shrivelling?
Maintaining a shady, lush canopy so the grapes retain as much freshness as possible.
Across France’s VDN AOPs, what is the average maximum yield in hL/ha?
30 hL/ha
Why don’t French winemakers of VDN want late harvest or botrytis-affected grapes for their wines?
Botrytis flavors would change the flavor profile, which is undesirable;
Vignerons aim for balance of acidity + residual sugar so they pick grapes before becoming over-ripe.
Grapes for VDNs must be picked at a minimum ___% potential alcohol.
14.8% potential alcohol, though some grape growers pick just a little later but before the grapes become over-ripe.
When are French Vins Doux Naturels fortified – before, during, or after fermentation?
During fermentation to make a sweet, fortified wine.
In g/L, what is the general range of residual sugar for French Muscat-based Vins Doux Naturels?
100 - 125 g/L
In g/L, what is the general range of residual sugar for French Grenache-based Vins Doux Naturels?
45 g/L (though most hover around 100 g/L)
What is the fortifying agent used in Vins Doux Naturels?
What is the typical ABV for the fortifying agent?
A neutral spirit that doesn’t compete with the character of the grapes; 95-96% ABV.
The fortifying spirit in VDNs is added when the fermenting must reaches what ABV?
5-8% ABV
French Vins Doux Naturels are fortified to what ABV range?
15-18% ABV (which is only ~5-10% of the total volume of the wine, which is why VDNs aren’t so spirity.)
VDNs made from white grapes:
- Are they typically fermented on or off the skins?
- What can producers do to extract more aromas from the grapes?
- Is the free run typically blended with press juice or no?
- Typically fermented off the skins;
- Some producers allow short period of skin contact (6-24 hours) to extract greater aromas from the skins;
- Keeping free run separate or blended is up to the producer, so it varies.
Because unaged white VDNs are meant for near-term consumption after release, how do the producers ensure the wines are fresh?
The must is chilled and stored anaerobically for months and then fermented on demand (when there is demand).
Are red Vins Doux Naturels typically fermented on or off the skins?
On the skins
When are red Vins Doux Naturels typically fortified?
- While the must is fermenting on the skins, or
- After the grapes are pressed
Why?
- While the must is fermenting on the skins;
- This helps with extraction of color, flavor, and tannins.
What post-fortification technique do some winemakers employ to maximize extraction for their red VDNs?
Continued skin maceration
They also use **pumpovers and puchdowns **during fermentation to help with extraction.
In what vessels are red and white Vins Doux Naturels typically fermented?
Why?
Stainless steel - allows for easy temperature control
White VDNs are fermented around what temperature and what does this do?
- 15C / 59F;
- Enhances fruity esters.
Red VDNs are fermented around what temperature and what does this do?
- 28C / 82F;
- Promotes extraction but retains fruity flavors.
What is the term used on VDNs denoting the wine is unaged, young and fruity?
Give the term used in Maury and in Banyuls.
- Grenat (for Maury);
- Rimage (for Banyuls).
For the oxidatively aged red Vins Doux Naturels, are the barrels usually topped up?
No - not topping up encourages oxidation and oxidative aromas and flavors.
