Q

Broadly speaking, what is the main difference between the vineyards on the plain and those on the hillsides?

A

Plain - deeper, more fertile soils which promote vegetative growth (better suited to high yields for inexpensive wines)

Hillsides - less fertile and better draining, promoting slower growth and higher quality fruit

16
Q

Why is Gewürztraminer picked late in Alsace?

A

To achieve fully ripe skins, maximise aromatics and avoid unripe tannins

17
Q

What are the main characteristics of Pinot Blanc?

A

Early budding

Early ripening

Can accumulate high levels of sugar (thus medium to high potential alcohol)

Susceptible to botrytis and downy mildew

18
Q

Why are picking dates for Pinot Gris an important topic in Alsace?

A

Can see a very rapid increase in sugar levels accompanied by a drop in acidity

Climate change and canopy management are enabling earlier picking

19
Q

What is the only black grape permitted for AOC wines in Alsace

A

Pinot Noir

20
Q

What are the training systems required by AOC regulations?

A

Single or double Guyot

21
Q

Why are fruit zones and canopies generally trained higher than in other regions?

A

Fruit - to avoid frost

Canopy - to maximise exposure to the sun. Spacing between vines must also be wider to avoid shading

22
Q

What is the typical planting density in Alsace?

A

4400 to 4800 vines per hectare

23
Q

What are the main pests and diseases in Alsace?

A

Powdery and downy mildew

Grape vine moth

Esca

24
Q

What percentage of Alsace vineyards are certified organic?

A

15%

National average is just under 10%

25
Q

Why does Alsace have a long harvest period?

A

Due to the range of styles being made (dry to sweet) and diversity of sites

26
Q

What adds to the cost of production for vineyards on steep slopes?

A

Hand picking is necessary

AOC regulations state that all Grand Cru vineyards (on the steepest slopes/terraces) must be picked by hand

27
Q

What is the main aim of most winemaking in Alsace?

A

To preserve primary fruit character in single varietal wines

28
Q

Why do some producers use pre fermentation skin contact or leave pressed grapes longer in the press?

A

To extract flavour

To enhance texture

29
Q

Why is Gewürztraminer likely to be fermented at warmer temperatures than Muscat, Riesling and Sylvaner?

A

Has pronounced aromas and high sugar levels. A warmer ferment does not affect the flavours and is desirable to ensure an effective ferment to high alcohol levels

30
Q

Why are inert fermentation vessels used?

A

No additional flavours are desired

31
Q

Why do smaller high quality producers favour ambient yeasts?

A

Believe they contribute to terroir expressive wines

32
Q

Why is malolactic conversion generally avoided for white Alsace varieties?

A

The aim is to retain primary fruit

33
Q

What is the maximum permitted yield for Alsace AOC wines?

A

80 hl/ha

34
Q

How many grand cru vineyards are there in Alsace?

A

51

35
Q

What is the main difference between vendange tardive and selection de grains nobles wines?

A

There is no requirement to have botrytis affected fruit in vendange tardive or for the wine to be sweet

Selection de grains nobles must be sweet and from botrytised fruit

36
Q

Why do many growers sell grapes to cooperatives and large wineries?

A

The average vineyard holding is v small - around 3.5 hectares

37
Q

What makes wine production in Alsace particularly notable (in terms of style)

A

Producers will often make many different styles from many different grape varieties across all quality levels

38
Q

What are the 4 sweetness levels in Alsace?

A
