11 - Germany Flashcards
Growing environment in Germany (climate, rivers and topography)
Climate
- Cool continental
- cold winters
- Frost spring
- 500-800mm rain often in summers
- Autumns long and dry
Rivers: moderates -> site selection
Topography: Taunus and Haardt provide shelter from wind and rain
Baden: southerly, drier, warmer, sunnier
Match the soil type with regions and grape varieties
Outline the costs and benefits to growing vines on steep slopes
+ sunlight
+ draining soils
+ frost
- Cost of labour
- Specialist machines → $
- Soil erosion → $
Outline why vintage variation has reduced and quality improved in recent years? (4)
- Climate change
- Clonal selection
- Summer pruning
- Selective hand-harvesting
Outline changes in canopy management techniques
Individual stakes - steep slopes with cane tied to top →declining due to shortages of labour
Single/double guyot
with:
1. VSP - favoured especially in larger vineyards
2. Pendelbogen - replacement-cane arched to improve sap flow → more viable buds
What % of vineyards are organic? Why is this not higher?
9%
- Disease risk from humid summers
- helicopter sprays
In which situations would hand-harvesting be used vs. machine harvesting?
Hand
- Slopes
- Botrytis - multiple passes
- HQ wines
Machine
- Flat vineyards → high vol wines
Describe the characteristics of Riesling
- Late budding and ripening
- Thick wood
- High yielding
- Resistant to mildews
- Susceptible to BBR
- green → tropical; floral; toast, honey, petrol
- High acid with variety of sweetness
Why did Riesling plantings decline in the 70/80s and why have they increased recently?
- Difficulty achieving ripeness
- German crosses
- Improved vineyard mngt and rising temps
Describe the characteristics of Muller-Thurgau
- High yielding
70/80s - Liebfaumilsch
- Simple fruit, floral
- Med acid
Describe the characteristics of Spatburgunder
- Early budding/ripening
- Vulnerable to: EVERYTHING
- Strawberry, raspberry, red cherry, oak, earth, game, mushroom
- High acid, low-med tannin, med alcohol
What factors have driven increased plantings of Spatburgunder in Germany?
- Warming climate
- higher-q clones
- CM have also improved consistency
- Wholebunch helped contribute tannins without use of costly oak
- Increased demand
Describe the characteristics of Dornfelder
- Deep colour, fruity/floral, high acid
Two styles:
- Sour cherry and blackberry, some RS, fruity, easy drinking
- More complex, tannic structure and oak
Describe the characteristics of Silvaner
- Plantings declined
- Less acid /aromatics than Riesling
- Green → tropical fruit
- Franken: HQ, earthy, med-med(+) acid, med bodied
Describe the characteristics of Grauburgunder (Pinot G) and Weissburgunder (Pinot B)
Increasingly popular
Grau
- likes heavy soils
- Stone + tropical fruit, honey.
- Dry - sweet, med acid, med-full body.
Weiss
- citrus and stone fruit
- Med(+) acid.
What other grapes are grown in Germany?
- Chardonnay
- Portugieser
- Schwarzriesling (Pinot M)
- Trollinger (Schiava)
- Lemberger (Blaufränkisch) - fruity, simple, early drinking
Why were crossings developed and how did they become so popular in Germany?
What are they used for and what are their advantages and disadvantages?
- cope with cool climate
- to ripen sufficiently
- to meet min. must req
- Popular to use in mass-production e.g. Liebfraumilch
Advantages:
- Ripen sufficiently even in cool years
- Easier to grow
- Higher y
Disadvantages:
- Often lack acid for balance
- Generally less aromatic
→ there are exceptions
Which two winemaking teq may be particularly useful when dealing with Germany’s climate?
- Enrichment
- De-acidification: Mostly for high volume production
