17 - Alsace Flashcards
how is Alsace unusal for a French wine region?
most of its wines are varietally labelled
Climate in Alsace
Cool to Moderate Continental
The more northerly part of the vineyard area has the coolest climate and the least protection from the Vosges
Region near Vosges Mountains
Alsace
What mountains shelter the vineyards in Alsace from the prevailing westerly, rain-bearing winds?
The Vosges Mountains
- what affects the climate in Alsace?
- how does it affect the grapes?
- what can the negative effect be?
Vosges Mountains:
- shelter the vineyards from the prevailing westerly, rain-bearing winds
- lack of clouds results in sunny summers & dry autumns
- these conditions ensure that the grapes can achieve high levels of sugar ripeness
- in the driest years drought can be an issue
hazard in Alsace
drought in the driest years
best vineyards are located
- on the steepest slopes with east & south-east aspects
lesser vineyards lie …
on the plain between the Vosges foothills and the Rhine
what are the grapes that are grown between the Vosges foothills and the Rhine used for
the production of Crémant d’Alsace
(the local AC sparkling wine)
soil & geology in Alsace
- dramatic geological history
- great variety of soils in the vineyards that lie on the foothills of the Vosges
- this geological complexity is a key factor that contributes to the variety of styles of wines produced
- the influence of geology on wine production is more clear here than in many other regions
geology mentioned about Alsace & Burgundy (kap. 16)
- Burgundy
“The soils in Burgundy are very varied. A large number of small geological faults, combined with gradual erosion, mean that precise soil types change significantly over small areas. These variations are often linked to subtle changes in the styles of the wines although the exact role the soil plays in this is the subject of much debate. What is certain is that the soils on the hillsides tend to be shallower with better drainage, whereas the soil on the flat land is deeper and more fertile” - Alsace
“Alsace has had a dramatic geological history and as a consequence there is a great variety of soils in the vineyards that lie on the foothills of the Vosges. This gelogical complexity is a key factor that contributes to the variety of styles of wines produced, and the influence of geology on wine production is more clear here than in many other regions.”
grape growing practices in Alsace vary depending on …
… whether the vineyards are on slopes or on the plain
grape growing practices in Alsace
- On the slopes:
- vines are trained low to benefit from radiated heat
- the rows are oriented to maximise the vine’s exposure to the sun
- harvesting is done by hand - On the plain:
- the vines are trained high to minimise the risk of spring frost
where and why are the vine’s trained high/low in Alsace?
high: on the plain. To minimise the risk of spring frost
low: on the slopes. To benefit from radiated heat
Viticulture in Alsace
- organic & biodynamic viticulture is widely practised
- in part due to the low disease pressure in the sunny, dry conditions
challenge at harvest in Alsace
- logistical
- have a number of small plots of vines planted with different varieties
