Germany L4.D3 Flashcards
(146 cards)
Did the 1830s saw the introduction of new wine laws, based on must weight of grapes?
Yes
What effect had 2 World Wards on Germany’s wine business?
Both wars had a devastating effect on Germany’s ecocnomy and its exports. High volumes of inexpensive branded wines started to be produced.
What is Flurbereinigung?
A program of vineyard restructuring, that involved the consolidation of many small, fragmented vineyards and the building of access roads, both aimed at increasing efficiency, making machanisation easier and so reducing the costs of viticulture. Without this, many vineyards would have become economically unviable.
What would have happened if Germany didn’t start the Flurbereinigungsprogram?
Many vineyards would have become economically unviable.
What is Germany’s overall main climate?
Cool continental climate
What is the location of German vineyards in latitudes?
The wine producing regions lie aroung 49-50N.
Why is site selection in Germany crutial for grape ripeness.
Regions might otherwise be too cold if not chosen for the right vineyard site, and grapes aren’t able to ripen fully.
What vital role does the Rivers play in Germany?
They radiate the heat; moderate temperatures and extending therefor the growing season, making many regions viable for grape growing and grape ripeness.
Alongside what are most of Germany’s vineyards situated?
Most are situated along the river Rhine and its tributaries.
What are often the best vineyard sites found in Germany?
The best sites are often on steep, southfacing slopes for a max. sun exposure. Some of them are extremely steep up to a gradient of 70%.
What are the main viticultural risks, vineyards in Germany face?
- In spring the risk of major frosts, but can/wil be mitigated by the rivers and planting on slopes.
- Warm, wet summers eventhough there is just 500-800mm of rain (not much) it falls mainly during growing season, increasing risk of fungal disease, dilution.
- Heavy (hail) storms
What important role do the German mountain ranges Taunus & Haardt play?
They shelter the vineyards from cold winds and the worst of the rain.
Why is vintage variation in Germany reducing?
Due to climate change and global warming but also du to significant advances in vineyard management techniques.
Why are vineyards not planted higher up the hills at higher latitudes in winegrowing regions?
Because the temperatures get colder and in terms of higher latitudes its not an advantages, when you are closer to the equator it can truly make a difference in ripe /over-ripeness, but in higher latitudes it can make grapes struggle to ripen fully. Mainly the vines are not planted above 200m above sealevel.
Why do the soils play an important role in grape ripening?
They play an important role in fruit ripening in the coolest regions. The dark-coloured slate (Mosel/Ahr), retains the heat and radiates it out at night.
What soiltype is mainly found in the Mosel / Ahr?
Dark-coloured slate
What soiltype is mainly found in Baden, Pfalz, Rheinhessen & Franken?
There are significant pockets of calcareous soils, good for planing Pinot Noir/Blanc and Chardonnay.
What soiltype is preferred by Grauburgunder?
Heavy clayey soils
Is erosion a problem in Mosel/Rehingau? And what do they do about this?
Yes, vineyard owners are regularly forced to winch soil and rocks back up the slopes adding to costs of vineyard maintenance.
Why is good canopy management in Germany so important?
It is essential to maximise sun exposure on the grapes and also to improve air circulation in order to reduce the risk of disease in wet summers.
How large is Germany’s vineyard size since 2018?
100,000 ha, being the 7th largest country with area under vine.
What is Germany’s average annual production?
9 million hL
How has fruit ripeness improved in Germany? (!)
Due to better clonal selection, summer pruning, green harvesting and selective hand harvesting.
How are the vines on slopes traditionally trained, and now seen way less?
On the slopes vines were staked individually with canes tied at the top.
