1
Q

What appellation do 80% of VDNs come from?

A

Roussillon

2
Q

What is the general climate for the majority of VDN PDOs?

A

Mediterranean

3
Q

What is the name of the wind that affects Roussillon?
How does this wind effect the region?
How does it effect the vines?

A

Tramontane
It’s a strong, dry cold wind that comes from the northwest. Similar in effect to the Mistral, but follows a different path, between the Massif Central and the Pyrenees.
Greater transpiration, when combined with the warm climate, and therefore more concentrated grapes.

4
Q

How does higher concentration of sugar in the grapes affect winemaking choices and outcomes?

A

Positive - More sugar means the juice can ferment longer and still have the desired level of residual sugar. This also means less fortifying alcohol is needed.
Negative - It does reduce juice yield.

5
Q

What are the two kinds of Muscat used for VDNs?

A

Muscat Blanc a Petit Grains

Muscat of Alexandria

6
Q

What are the key characteristics of Muscat Blanc a Petit Grains? (5)

A
  1. Most widely planted in France
  2. Smaller grapes than MoA and presumably therefore more flavour intensity.
  3. Drought tolerant
  4. Susceptible to powdery, botrytis bunch rot and mites
  5. Plantings are increasing as it’s popularity for dry table wines increases
7
Q

What are the key characteristics of Muscat of Alexandria? (5)

A
  1. Bigger grapes than MBaPG
  2. Higher sugar levels than MBaPG
  3. Drought tolerant
  4. Susceptible to powdery and botrytis bunch rot
  5. Plantings are decreasing as wines are said to be less refined
8
Q

What are the key characteristics of Grenache Noir? (5)

A
  1. Late-ripening
  2. Drought tolerant
  3. High yielding, which must be controlled or colour concentration can be lost
  4. Has fast sugar accumulation
  5. Susceptible to coulure at fruit set, downy, phomopsis and botrytis bunch rot
9
Q

What are the three additional varieties that may also be part of the blend for VDNs?

A

Grenache Blanc, Grenache Gris and Macabeu

10
Q

What canopy management techniques are used and why?

A

A shaded canopy is needed to reduce sunburn and shrivel.

11
Q

Generally, what are maximum yields?

A

Small, 30hL/ha

12
Q

What is minimum potential alcohol for picking?

A

14.8%

13
Q

Describe the harvest?

A

Usually as early after minimum potential alcohol is reached to retain as much acidity as possible.
By hand, often with several passes depending on ripeness.
Late harvest/botrytis character is not desired

14
Q

What is the range of minimum residual sugar across appellation?

A

Muscat - 100-125g/L
Grenache - 45g/L
Although Grenache can be also be around 100g/L in practice

15
Q

What spirit is used for fortification of VDNs and why?

A

Neutral, 95-96% ABV

So as to not alter or compete with the character of the base wines

16
Q

When is fortifying spirit added and how does this effect the final wine?

A

At 5-8% ABV to make
15-18% ABV wine.
As only 5-10% of the final wine is spirit, the wine has less spirity character.

17
Q

How is skin-contact used for VDNs?

A

For white grapes - fermentation usually takes place off skins, although a portion of pre-ferment maceration may occur, and the producer may use press cut blending to increase body.
For black grapes - fermentation is fermented and fortified on skins, as the fortification will help extraction of colour and tannin (needed for ageing). Pump over and punch down will be used for a couple of weeks past fortification

18
Q

When is oxygen avoided in the production of a VDN?

A

When making an unaged VDN from white grapes - the must can be sealed and cold stored and the fermented on demand. This will keep primary fruit flavours fresh.

19
Q

What fermentation vessels are typically used and why?

A

Stainless steel tanks to regulate temperature control.

20
Q

What are fermentation temperatures for white and red VDNs?

A

White - 15 C (cool)

Red - 28 C (warm)

21
Q

What maturation methods are used for youthful, unaged VDNs?

A

Closed, stainless steel vessels at cool, constant temperatures, protected from oxygen, possible by inert gas blanket

22
Q

What are the typical aromas/flavours of youthful unaged VDNs?

A

Muscat - floral, grapey, peach pear, honey

Grenache - blackberry, raspberry, plum

23
Q

What are the options for maturation vessels for oxidatively aged wines? (3)

A
  1. Old oak barrels, not topped up
  2. Glas demi-johns (bonbonnes), not quite full, unsealed, left outside in the sun.
  3. A mixture of the two.
24
Q

What are the two VDN appellations in the Rhone Valley?

A
  1. Muscat de Beaume-de-Venise

2. Vin Doux Naturel Rasteau

25
Q

What is the name of the mountain where the grapes are planted on in Muscat de Beaumes-de-Venise? How does this effect the grapes?

A

Dentelles de Montmirail.

Provides shelter from the Mistral, helps ripening.

26
Q

Describe a typical MdBdV (style and flavours/aromas)

A
Always unaged.
Made from MBaPG (white)
Can also be rose or red (MaPGR)
Medium bodied, medium acidity, low alcohol (15%).
Blossom, grape, peach and honey.
27
Q

Describe a typical Rasteau (style and aroma/flavour)

A

Can be white, rose or red (most is red)
Can be unaged or oxidative

Low-med alcohol (16-18%)
