Alsace Flashcards
What is the climate in Alsace?
Continental with cold winters and warm, sunny and unusually dry summers
What makes the climate in Alsace warm, sunny and unusually dry?
Protection from the Vosges Mountains in the west
What historical events have influenced the wines of Alsace?
Frequent changes in control between France and Germany
Germany influence is seen in aromatic varieties such as Riesling and Gewürztraminer
How do the Vosges Mountains influence rainfall?
Most rain clouds stop on the western side of the mountains so the eastern side where viticulture is found only has around 600mm per year (less than half of what falls in the west)
What issues are there associated with rain in Alsace?
- Summer drought due to moderate rainfall (irrigation not permitted)
- Rain spread evenly throughout the year - can cause issues for flowering and fruit set
What are the wettest and driest months in Alsace?
August - wettest
September/October - driest
What factor is key for ripening in Alsace’s northerly latitude?
Long sunshine hours
What is the most important drying influence in Alsace?
The Fohn wind
Warm wind - raises temperature and reduces fungal disease pressure
What growing conditions do the topography of the Vosges foothills provide?
Diverse sites at a range of altitudes suitable for growing many different grape varieties
Where are the best vineyards in Alsace generally situated?
200-250m altitude
Facing south, south/east or south/west for maximum sunlight interception
What phrase is often used to describe the soils of Alsace?
‘A mosaic of terroirs’
Broadly speaking, what is the main difference between the vineyards on the plain and those on the hillsides?
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
What are the four permitted noble grape varieties?
Riesling
Gewürztraminer
Pinot Gris
Muscat
What are the main characteristics of Riesling?
- Suitable for cold climates
- Late budding
- Needs long sunlight hours and good drainage to ripen fully
- Can produce good quality at relatively high yields
- Good disease resistance to mildew and rot
What are the main characteristics of Gewürztraminer?
- early budding
- early ripening
- vigorous - lots of canopy management needed
- vulnerable to chlorosis, powdery mildew, grey rot, grapevine moth
