Germany Flashcards
(161 cards)
What is the main climate of Germany?
Cool continental
Why is site selection important?
Due to the high latitude
What plays a moderating effect on the cool climate?
-Rivers (Rhine)
-Radiate heat, moderating temperatures and extending the growing season
What is the best exposure for vineyards?
-South-facing slopes to maximise sun exposure
- can be very steep up to 70% gradients in Mosel)
What are the winters like in Germany?
-Cold, allows eiswein production
What is a risk in spring?
-Frost, rivers and plantings on slopes to mitigate the effects
What about rainfall?
-500-800 mm of which lots falls in summer
-risk of: fungal disease, dilution of grapes and when heavy storms: hail
What are the autumns like in Germany?
-long&dry extending the growing season
-grapes can accumulate high levels of sugar suitable for Pradikatswein
-morning mist from river can help botrytis develop
What are the 2 mountains in Germany, what do they do?
-Taunus&Haardt
-shelter vineyards from cold winds & worst rain
Which soil type is predominant in the Mosel&Ahr? describe its features
-dark-coloured slate
-retains heat during the day&radiates the heat during the night
Which grape varieties grow best on calcareous soils?
-Spatburgunder, weissburgunder & chardonnay in baden, pfalz & rheinhessen
-in Franken, Silvaner grows best on calcareous soils
Which soil does grauburgunder prefer?
-heavier clay soils
What is a major problem in the Mosel and Rheingau regarding soils?
-Erosion on steep slopes
- soils&rocks need to be placed back on the slopes = high costs for vineyard maintenance
How many ha under vine does Germany have?
100.000
around 9 million hl
Why is good canopy management important?
-to maximise sun exposure
-air circulation to reduce risk of disease caused by wet summers
What shift has there been regarding grape varieties?
-From 90% white to 39% red in 2017
- ince 1990s more interest in Grau & weissburgunder and to lesser extent in chardonnay
Why is Riesling so popular in Germany?
-can survive the cold german winters
-late budding with thick wood -> fairly frost resistant
When does Riesling ripen? What does this mean?
-Late-ripening
-needs good sun exposure & dry autumns
-cooler years and sites: may not fully ripen
How is greater consistency in terms of ripening Riesling achieved?
-Improved vineyard management techniques
-rising temperatures
What about the acidity levels in Riesling?
-High
-Maintains high acidity levels, even when fully ripe
-provides good balance in sweet wines
-ageing potential
What about sugar levels in Riesling?
-Can develop high natural sugars
-also susceptible for botrytis
- suitable for sweet wine production
Why was Muller Thurgau developed?
- To have a grape variety that ripens earlier than riesling in a cool climate
What are the characteristics of Muller Thurgau?
-High yielding -> inexpensive blends such as liebfraumilch
-lower acidity and structure than riesling
-simple floral&fruity aroma
Which style of spatburgunder can be produced in Germany?
-High quality, complex, often oak aged (less new oak)
