Austria Flashcards
How many ha under vine does Austria have approximately?
45000 ha
What happened in 1985?
-Large producers added diethylene to the wine (anti freeze agent) to increase volume&stimulate sweetness
-discovered in 1985
-from 30 million litres exported to under 5 million litres
What about production now?
-53 million litres
-value tripled since 1985
- consumers paying premium prices for high quality wine
What is the overall climate of Austria?
Cool continental
in Which parts is the climate influenced? explain why
-North (weinviertel) -> cold northerly winds
-South (Steiermark)- > Adriatic sea thus warmer
-East (Burgenland) -> near Hungary, Warmer Pannonian climate
-West (vineyards on danube)-> cool breezes from alps
Name weather hazards in Austria
-Spring frost
-Hail in Steiermark
-low rainfall = water stress, especially with thin, free draining soils
What are the 2 major soil types of Austria?
-thin soils over rock (granite or gneiss)
-richer soils -> loess
Which soil type does Riesling tend to grow better, and GV?
-thin soils for Riesling, requires less water
-Loess or clay for GV, due to greater requirement of water
Which training system is now commonly used?
-Single or Double guyot for better quality
-in past high cordon trained vines for mechanisation and high volume wines
Where is machine harvest common, and hand harvest?
-flatter areas: Burgenland, Weinviertel
-hand harvest= steeper slopes around Danube river such as in Wachau, Kremstal and Kampstal, also vines planted on hand built steep stone terraces
What about disease pressure? This had led to..
-Low due to moderate rainfall
-from 450 mm in Weinviertel to 850 mm in Steiermark
-14% organic vineyards and 9% sustainable
What grape varieties are most planted?
-White grapes, 2/3 of plantings
What about the skins of Gruner Veltliner?
-Thick skinned, when being left too long in contact with whine -> phenolic compounds or bitter taste
- chemical compound rotundone which gives peppery aroma also present in skin
Describe the style of gruner veltliner
-medium(+)- high acidity, not oaked
-simple/inexpensive= simple green&citrus fruit, early consumption, acceptable to good quality
-very good- outstanding: pronounced citrus&peach, complexity with ageing potential, sold for premium prices
Zweigelt is a crossing of..
Sankt Laurent x Blaufrankisch
What are the features of zweigelt?
-ripens early& more easily than Blaufrankisch, producing high yields
-vigorous = canopy management& leaf removal needed
-when potassium deficiency= withering of grapes before they ripen, leads to lossof crop
-not susceptible to frost or rot thus widely planted
Describe the style of Zweigelt
-med(+) acidity, med tannins
-red fruit dominated (cherry)
-inexpensive to mid-priced style of easy drinking, fruity and unoaked
-very good for premium prices: full-bodied, oaked with ageing potential
Which style does Welschriesling produce in Steiermark?
-fresh, neutral, unoaked and dry
-acceptable to good and inexpensive
-plantings decreasing due to decrease in consumption
Which style does Welschriesling produce in Burgenland?
-can produce sweet wines near humid Neusiedlersee due to humid conditions -> noble rot (also due to thin skin)
-Trockenbeerenauslese or BA: high acidity, pronounced tropical and dried fruit, can bottle age
-very good to outstanding, premium prices
What are the features of Blaufrankisch?
-early-budding = prone to spring frost
-late-ripening = needs warm climate to ripen (Burgenland)
-thick-skin= less prone to fungal disease, suitable to humid area such as Neusiedlersee
-high yields = managed, otherwise green aromas
Describe the style of Blaufrankisch
-med(+)-high tannins, high acidity, deep colour and black fruits
-good/mid-priced= simple, fruity, little/no oak
-very good/outstanding: pronounced black fruits, spicy from oak, high tannins, premium priced. Most age worthy and intense red wines
-Leithaberg Dac & Mittelburgenland DAC = good reputation for blaufrankisch
What style can Riesling produce ?
-Mainly planted in niederosterreich
-warmest sites&thin soils
-dry, full body, med alc, high acidity, ripe stone fruit and sometimes tropical
-can bottle age for 10-20 years
-nutty, honeyed,petrol
-very good - outstanding, premium prices
What are generally the winemaking options for white wine?
-aim is to preserve primary fruit and varietal characteristics
-skin contact to maximise aroma
-fermentation in neutral vessel, temperature controlled
-no malolactic conversion
-maturation: ss or old oak, fine lees for 6 months or more to add texture
-most wines are fermented to dryness
What are generally the winemaking options for red wine?
-fermentation in large open top vessels: punch down or pump over
-ambient yeast may be used
maturation: ss or old oak (300-600 l) to soften tannins without extraction of flavours of new oak
-premium wines: barriques with some proportion of new oak or acacia vats to allow some oxygen without extracting vanilla aromas
Which category is the protected designation of origin?
-Qualitatswein
Which 2 categories fall within qualitatswein? elaborate
-Klassik: vintage declared, varietal character
-Reserve: dry, min 13% abv, harvested&released later than standard wine
Why was DAC established?
-appellation system to promote regional typicity
what requirements are set for DAC?
-Permitted grape varieties
-need to meet tasting criteria
-within DAC = gebietswein, ortswein (village), riedenwein (single vineyard)
What is the Osterreichische Traditionsweinguter?
- a group of producers who classify their vineyards based on soil types and climate
-81 vineyards erste lage: must be dry, can put 1OWT on label if they use one of the 2 traditional varieties
Which is the biggest grape growing region of Austria? Name the regions within it
-Niederosterreich, 2/3 plantings white:
-Weinviertel, wachau,kremstal,kampstal,wagram & pannonian plain in south east
What is the location of Wachau?
North bank of Danube river
What is the aspect of the best vineyards in Wachau?
-steep terraces, south facing sites for maximum sunlight interception
-stony terraces retain heat& release at night = very ripe fruit
What influences the climate of Wachau?
-Danube river= humidity, can cause noble rot which is not always desired by producers due to preference for dry wines
-low rainfall = irrigation neccessary
What are the soils in Wachau?
-Gneiss for Riesling and Loess for Gruner veltliner
