Germany Flashcards
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)
What is a winemaking technique which can be used for spatburgunder?
-Whole bunch fermentation
-to add tannins from stems without the use of oak
What is the style of Dornfelder? describe the 2 styles
-deep in colour
-high acidity
-fruity&floral notes
-style 1: fruity, early drinking, can have little residual sugar, sour cherry and blackberry
-style 2: complex style, ageing potential,lower yielding, focus on tannin&structure and fermented/aged in oak
In which areas is Dornfelder successful?
-Rheinhessen and Pfalz
What is the style of Silvaner?
-lower in acidity and less aromatic than Riesling
-high volume, inexpensive wines
-green to tropical fruit
-when yields controlled: high quality, dry, earthy character
Where is Weissburgunder grown? Describe the style
-Pfalz, Baden, Rheinhessen
-very good quality with aromas of citrus and stonefruit
-medium (+) acidity
Where is grauburgunder grown? Describe its style
-Pfalz, Baden, Rheinhessen
-sometimes oak aged
-very good quality, medium acidity, stonefruit and tropical, sometimes dried fruit
-dry & med body to sweet & full body
Since when is Chardonnay allowed? producing which style?
-1990
-high quality often oak aged from warmer areas: Kaiserstuhl in Baden and Southern Pfalz
What about the crossing Scheurebe, why is this variety successful?
-others too high levels of sugar and lower acidity = no balance
-scheurebe= full bodied, ripe grapefruit and peach with lower acidity than Riesling but still age worthy
What are 2 common practices regarding winemaking with inexpensive high volume wines?
-enrichment (up to 3% abv and 2% in baden, not allowed in pradikatswein)
-de-acidification
What winemaking technique can be used for premium Riesling?
-fermentation and maturation in old oak vessels
Which type of oak is used in Germany?
-German oak for large oak vessels (1000 litres fuder of Mosel or Oval shaped 1200 ltr)
-French oak for small barriques
Why is stainless steel the main fermentation vessel in Germany?
-for inexpensive wines: easy temp. control, cleaning and use of large vessels + no oxygen and addition of flavours
-premium Riesling: to maintain primary aromas
Why is new oak not used for Riesling?
-Could mask primary aromas
How was sweet wine traditionally made?
-residual sugar was fermented to dryness
-post-fermentation: sussreserve added (unfermented or partially fermented grape must)
Can sussreserve come from the same must as the wine? If so, explain
-Yes
-Pre-fermentation, part taken from must -> clarified, chilled and s02 added to remain fresh
-then: added back to fermented wine to create desired sweetness level
-min/no alc may reduce the alcohol level of the final wine (depending on the amount added)
-said to give less balanced wines
What is the other method of making sweet wines?
-stopping fermentation by adding so2 when desired residual sugar levels are reached
-racked or filtered
-for quality concious producers
What about the fermentation of (T)BA & Eiswein?
-high must weight and slow fermentation (up to several months for TBA)
Results in: fermentation can stop naturally leaving high levels of residual sugar behind and low levels of alcohol
How are inexpensive red wines often made?
-thermovinification for quick extraction of colour and flavour
-may even be fermented off skins for fruity red wine with low tannins
-no oak
Which winemaking techniques are common for high quality red?
-cold maceration
-whole bunch fermentation
-oak maturation
Which 4 quality levels of wine are based on the must weight?
-Deutscherwein
-Landwein
-Qualitatswein
-Pradikatswein
If the wine is classified as Deutscherwein, where are the grapes sourced from? nad as Landwein?
-Deutscher wein: in or outside germany, no geographical indication
-Landwein: if region is stated on the label, at least 85%
Which sweetness levels can kabinett have?
-dry to medium sweet
describe the style of kabinett
-lightest body and highest acidity
-green & citrus aromas
What range are the alc percentages of kabinett?
-7-12% abv
What is the style of spatlese compared to kabinett?
-fully ripe grapes, picked 2 weeks later than kabinett
-also min. 7% abv
-greater concentration of riper fruit (stonefruits for riesling), higher alc levels
-
What style can auslese produce?
-dry to sweet
-from specially selected extra ripe grapes
- mostly hand harvested but not obligated
-riper and more concentrated than spatlese
-min 7% abv
-honey characteristic when affected by botrytis, adding to complexity
Why is hand harvest obligatory with Beerenauslese?
-because berries are carefully selected
What is the style of Beerenauslese?
-Sweet, min. 5.5 abv%
-no botrytis obligatory but common
-very ripe and dried stonefruits
in what years is Beerenauslese produced?
-when grapes are affected by noble rot
due to brief periods of humidity followed by sunny and dry afternoons
-very low yields + labour intensive = rare wines and expensive
How is eiswein made?
-berries need to be picked when frozen (below -7 degrees)
-fruit should be healthy: the unpleasant flavour of rot will be amplified along with other flavours
-need to be pressed when frozen: very small amounts of concentrated juice with high levels of acidity and sugar
What is the style of eiswein?
-high acidity, concentrated flavours of pure peach and grapefruit
-rare and sold at premium prices
Describe the style of TBA
-very high must weight -> affected by botrytis producing very concentrated, tiny shrivelled raisin-like grapes
-sweetness still balances acidity = ageing potential
-do rarely exceed 8% abv
-yields are extremely low (not more than 100 bottles per time), cannot be produced every year since botrytis is neccessary
=most expensive wine of germany
why do some producers use EU labelling terms?
-because consumers cannot tell what the residual sugar is of auslese, spatlese, kabinett or qualitatswein
- to create sweetness levels
up to how many grams of residual sugar is Trocken?
up to 4 grams
up to how many grams of residual sugar is halbtrocken (off-dry)
-4 to 12 grams
up to how many grams of redisudal sugar is lieblich (medium/medium sweet)?
-12 to 45 grams
Why do producers use Fernheib as labelling term?
-not defined by law
-who do not want to label as halbtrocken due to negative association
-can have slightly higher levels of residual sugar
What is goldkapsel?
-a gold capsule created in the Mosel
-No official labelling term
-indicated botrytis affected wines
- shorter capsules = higher levels of concentration than auslese
-longer capsules = even further levels
What are einzellagen?
- individual sites within wine producing districts
-from less than 1 ha up to over 200 ha
What are Grosslagen?
-collective vineyard sites
-can have einzellagen in them
-600-1800 ha
note: NOT CONFUSE WITH GROSSE LAGE VDP (one of top vineyards)
